Country of Origin: USA
Can be used to determine unknown pile lengths
Optional PIT-Professional reporting software allows advanced modeling and analysis
The Pile Integrity Tester (PIT) gives peace of mind that a pile or shaft is free of major cracks and voids, prior to construction of the superstructure. It may be used on most concrete or wood foundations. The PIT may also be used to test piles integral in the structure, such as those supporting existing bridges or towers, and may assess their length.
The PIT performs wave equation-based non-destructive foundation investigations known as Low Strain Impact Integrity Tests or Low Strain Dynamic Tests. These test may be performed by the Pulse (or Sonic) Echo or Transient Response Methods. With the PIT, any form of the test is performed fast, potentially making it possible to test every pile on a job site.
The PIT test consists of attaching one or two accelerometers to the foundation and using a hand-held hammer to impact it. The PIT collects the acceleration data and displays curves that reveal any significant changes in cross section that may exist along the shaft.
The Pile Integrity Tester is available in several configurations to match the needs of each user. Find out which model is right for you here.
PIT-X is much smaller and may read data from a wireless accelerometer. PIT-X has one data input channel, used to record the acceleration measured on the pile. This is sufficient for many, and perhaps most, applications. The analysis of acceleration data is usually performed in the time domain.
All models of the Pile Integrity Tester are battery powered, operated through a high visibility touch screen, and include a Fast Fourier Transform (FFT) feature and a license of PIT-W Standard Software. All comply with ASTM D5882 and many other codes and specifications.

Product information
The James Instruments Aquameter™ utilizes the latest electronic technology to measure the quantity of water within its sensing field. The unit has two modes of operation the pin mode, and search mode. In the pin mode, two pins are pushed into the material and a high frequency field is created between these two pins. In the search mode the unit uses a high frequency capacitive sensor to sample a large volume of the material, instantaneously. Changes in this electromagnetic field are directly proportional to the dielectric constant of the material through which it passes. As the dielectric constant of water is almost two orders of magnitude greater than most non-metallic materials, variations in this parameter can be correlated to the moisture content. After extensive testing of various materials, relationships between the change in this field and moisture content have been determined. These relationships have been digitized and implemented using the latest in micro-computer technology, thereby allowing the user the direct readout of moisture content for concrete, masonry, hard wood, soft wood, gypsum, and brick. The pin method has been found to be most effective in low density materials such as fir wood or pine wood. The search mode has been found to be most effective for higher density materials such as brick, masonry, gypsum and concrete.

It may store more than 200 individual tests with time and date indication.
The data is easily uploaded to a PC for inclusion in reports and data analysis. Data communication takes place via the RS-232 port and Windows compatible PC software. The unit allows the user to select sensitivity levels to adapt to varying conditions in the field.
Theory
The James Vu-Con®System uses the impact echo method to evaluate concrete and masonry structures. The impact echo method is based on the use of impact generated stress waves that propagate through the material and are reflected by both the materials external surfaces and internal flaws.
This method can be used to make accurate non-destructive measurements of thickness in concrete slabs and plates , and to locate internal flaws such as honey combing ,debonding and delaminations. It can measure thickness, locate cracks, voids and other defects in masonry structures where mortar bonds the masonry together. Finally, the impact echo method is not affected by the presence of steel reinforcing bars.
The method works by creating a short duration mechanical impact on the surface of the material under examination. This is typically performed by small steel balls that produce low frequency stress waves that propagate through the material and reflect off of other surfaces and internal flaws back to the surface used for testing (See diagram below) By recording and analyzing the vibration from the mechanical impact at the surface, thickness and other physical features (referred to in the preceding paragraph) can be determined. The advantage of using an impact rather than other more classic ultrasonic techniques is the low frequency and the long wave length of the stress waves that are produced. Low frequency stress waves treat concrete and masonry as a single elastic homogeneous material as they propagate through.
Unit
The Vu-Con® Analyzer provides the engineer with the sturdiest, most reliable system for impact echo analysis. No moving parts and implementation of the latest microcomputer technology has created a system that is both sophisticated and reliable. The unit comes with a 90 mm (3.5) by 115 mm (4.5) graphic display screen that is easily viewed in daylight. This allows rapid analysis of results in situ. It may store more than 200 individual tests with time and date indication.
The data is easily uploaded to a PC for inclusion in reports and data analysis. Data communication takes place via the RS-232 port and Windows compatible PC software. The unit allows the user to select sensitivity levels to adapt to varying conditions in the field.
The built-in menu system has provisions for determining all the parameters for the material under test. The thickness menu allows rapid display of the frequency spectra of an impact. Peaks are automatically found and highlighted for a given test. The velocity menu, for use with the dual transducer set, facilitates determination of the stress wave speed in a given material. This allows the operator to gather and analyze data quickly and easily in the field. Finally, the user can select from multiple gain settings for various material dimensions. There is also a selection of multiple data sampling rates and an adjustment for different trigger levels which help the user produce accurate and reliable results
Results
The resulting amplitude waveform from the transducer can be displayed for analysis both with respect to time and frequency. This is illustrated by graphs. The time domain waveform can be described as a sum of a series of different frequency waveforms.
This allows the user to:
Analyze the dominant frequencies of vibration found from the impact and determine thickness as well as distance to features within the material.
Compare the frequency spectra to obtain indications of homogeneity of the concrete.
Calculate the rate of decay of the vibrations to glean information regarding the sub-grade.
The Vu-Con™ System represents the latest technology in concrete ultrasonic analysis, allowing the engineer to see into the concrete surface.

System
The Emodumeter® has an automatic feature that computes the maximum amplitude, which eliminates cumbersome frequency scanning. Frequencies are automatically shown in the display and a cursor allows the user to move along the frequency spectrum. Also the time domain signal and the frequency spectrum can be stored and uploaded to a PC for further analysis and inclusion in reports.
Resonance Frequency
The Emodumeter® performs a Fast Fourier Transform that allows the identification of the resonance frequency in the Frequency Spectrum.
Durability of Concrete
The determination of flexural resonance is very important when studying the degradation of concrete under accelerated freezing and thawing cycles and aggressive environments on concrete specimens.
The advantage of resonance methods are:
1. Tests can be repeated over a very long period on the same specimen; the number of test specimens required is therefore greatly reduced.
2. The results obtained with the resonance method on the same specimen are more reproducible than those obtained with destructive tests and groups of specimens.
For the determination of the resonant frequency of materials, the Emodumeter® measures the resonant frequencies of the three different mode s of vibration Longitudinal, Transverse (Flexural) and Torsional.

Product Information
Concrete
The V-Meter MK IV™ is widely used and accepted for quality control and inspection of concrete. It can measure and correlate concrete strength to standard strength measurement, permitting non-destructive testing of complete structures. It will identify honeycombs, voids, frozen concrete, cracks and other non -homogenous conditions in concrete. Ultrasonic testing can be applied to new and old structures, slabs, columns, walls, fire damaged areas, hydroelectric structures, pipe, prefab and pre-stressed beams, cylinders and other concrete forms. A wide range of transducers are available.
Wood
V-Meter MK IV™ used on Wood Direct Mode:
V-Meter MK IV™ used on Wood Direct Mode:
V-Meter MK IV™, ultrasonic testing of wood can, nondestructively, detect knots, shakes, splits, grain orientation, windfall cracks and presence of decay and rot. Basic parameters such as modulus of elasticity and density can be calculated. Practical applications include field testing of utility poles and structures, grading in the manufacturing process, fire ladder inspection, examination of laminates and paper roll density. The velocity of ultrasonic energy pulses traveling in a solid material are related to the density and elastic properties of the material. The pulse velocity is thus a measure of density and elastic properties of the material. In transmitting ultrasonic energy through a coarse grained material such as concrete, ceramics or wood, it is necessary for the wave length of energy to be greater than the diameter of the largest grain particle. If it is not, all of the energy will be reflected back by the particles and none will reach the receiver. Typically, the 54 KHZ transducers are used for wood testing. The signal wave length is about 3 inches (75mm). Finer materials require higher frequencies for optimum resolution.
Ceramics
V-Meter MK IV™ used with Ceramic Sample:
V-Meter MK IV™ has been successfully applied to a range of ceramic products–including tile, refractory bricks and blocks, and kiln furniture–as well as graphite. In an increasing number of refractory and ceramic applications, the ultrasonic pulse velocity testing technique has been used with positive results. UPV testing has enabled users to improve their production processes, increase the integrity and quality of their products, and reduce scrap and reject rates-thereby saving both time and money. In today’s economy, such bottom-line benefits are difficult to ignore.
Technical
The instrument has an easy to view display (320 by 240 pixels). The backlit for daylight use, makes field work easier and faster, since the operator can identify good results in seconds without the problems related with the sun light reflection on the screen. The signals can be recorded in the instrument for review on the screen or for transfer to a PC.
Typically, the 54 KHZ transducers are used for concrete testing – the signal wavelength is about 75mm ( 3 inches ). Finer materials require higher frequencies for optimum resolution. The basic V-Meter MK IV™ contains a transmitter, a receiver and a very accurate high speed electronic clock. The transmitter generates an electrical pulse which when applied to a transmitting transducer, converts the electrical energy into a pulse of ultrasonic mechanical vibration. This vibration is coupled with the specimen under test by placing the transducer in contact with the specimen. At another selected point on the specimen another receiving transducer is coupled by mechanical contact. Each transmitted pulse of energy registers on the high speed clock. The first energy wave reaching the receiving transducer is converted back to an electrical signal and turns off the clock. The elapsed time is displayed on the LCD in 0.1 microsecond increments. The unit can also display and store the resulting waveform. This ensures the operator that a proper acoustic contact has been made with the surface of the material under test.
V-Meter MK IV™ Showing Elapsed Time:
V-Meter MK IV™ Showing Waveform:
V-Meter MK IV Standard 54KHz Transducers:
The standard transducers for the V-Meter MK IV™ are made for a 54 KHz high Q resonant frequency with a stainless steel housing. The connector is a ninety degrees to the face of the transducer to facilitate operation and getting proper acoustic contact. A push button and special cable are added to the reciever in order to store data while taking readings. The data can later be uploaded to a computer via the Veelinx™ software. An adapter is provided to utilize the receiver with standard co-axial cable.
The ultrasonic transducers are typically used in one of three configurations, direct, semi-direct and indirect mode. Direct is the most sensitive method as the receiving transducer will receive maximum energy from the transmitted pulse. Since the longitudinal pulses leaving the transmitter are propagated mainly in the direction normal to the transducer face. The travel time is affected by the concrete condition along the thickness of the member. Semi-direct transmission is performed with transducers on adjacent faces. This is the next preferred method. Finally, In-Direct the least preffered. with the transducers on the same face. This should be used only when it is impossible to have access to two faces of the material under test. The received amplitude of the method, for the same path length, is only about 2% of that received signal when using the direct method. Testing for shear waves can only be performed with the In-Direct method, with both transducers on the same face as the specimen under test.

Product information
The James Rebarscope® is the digital version of a classic rebar locator, rebar finder which enables the user to not only locate reinforcement bars but also determine rebar depth and the rebar size. The Rebarscope® rebar locator is also capable of locating non ferrous metals as well such as copper, aluminium, some stainless steels, wire, and more!
Rebarscope® Sensor:
Influence of Rebar Spacing on Results:
Maximum Depth of Rebar vs Bar size:
The eddy current sensor is specifically designed to react to the outer surface of the metal object. It is uninfluenced by small metal particles in the concrete, whether the concrete is fresh or hardened, wet, or dry. The eddy current sensor also allows the unit to locate both ferrous as well as non-ferrous metals in concrete and other non-metallic construction materials. This sensor has also been designed with temperature compensation circuitry as well. The temperature compensation circuitry not only improves accuracy and performance but allows the operator to use the equipment without a “zero” procedure first. As always only one sensor is required for all depth ranges and functions of the equipment.
The latest in microprocessor technology not only conditions the signal from the sensor for more accurate and dependable results but provides the user with the information they need. Rebar diameter can be estimated by using a simple system of comparison. All this is fully automated for consistent, repeatable results with increased resolution over previous models.
The microprocessor can also statistically analyze the data, searching automatically for minimum cover points, and the least cover of a group of points. A Cover Map or display of cover points as a symbolic map of a structure can assist the user in finding problematic areas. Built in memory can store over 80 thousand individual data points for later processing.
Rebarscope® with Head Phones:
Rebarscope® in Hard to Reach Location:
Feedback to the user can also be made via the direct view, sunlight readable digital screen, or via head phones. By seperating the sensor from the main instrumentation unit, difficult to reach area’s can be handled with ease.
Rebarscope® used on Wall with Scan Cart
Rebarscope® with Scan Cart:
Rebarscope® with P.C.:
The optional Scan Cart can be used to graphically display a cross section of the concrete and the location of the metal objects within. With its built in encoder objects can be located with both distance and depth recorded.
Rebarlinx® the fully integrated P.C. software allows the upload and storage of data points via USB. The ruggedized Rebarscope® provides rthe field engineer/technician with all the tools necessary to locate and determine what and where all metal objects are within the structure.
