When a manufacturer needed to validate the structural performance of a 38-ton on-highway vehicle, ITM deployed a 200+ channel synchronous datalogging system capable of capturing accelerometer, strain, GPS, and speed data at nearly 2 kS/s per channel…
Integrated Test & Measurement (ITM) offers specialized strain gauge testing field services that are essential for analyzing the structural integrity and performance of materials and structures under stress. By leveraging advanced technologies and deep expertise, ITM provides comprehensive solutions that cater to various industries, including aerospace, automotive, and…
Obvious signs of fatigue — cracks at the corners of doors — had begun to surface on an in-service Railcar. A railcar structural testing case study.
The most common strain gauge installation configuration is a 350 ohm, quarter bridge. Quarter bridge installations a generally the easiest and most economical installation for determining structural strain levels. In the quarter bridge configuration a single element strain gauge is mounted in the principle axial or bending strain…

Plant operators need to continuously measure bulk material levels/weight in their silos and hoppers to ensure their processes are running safely, efficiently, and without bottlenecks. Measuring these levels allows operators to automate vessel filling, verify material consumption, and prevent overfilling. What we offer ITM provides its customers with…
At ITM, we understand that our customers do not settle for good enough. When it comes to measuring and capturing data for real-world applications and structural analysis, you cannot compromise, so neither can we. Instead of having to pick and choose the most critical locations to measure, we…
Our test engineers are often called upon to deploy unattended or “black box” data acquisition systems in the field. These systems are deployed on machinery, vehicles, and industrial processes to constantly record strain and vibration data at sample rates between 100 and 100,000 Hz. That adds up to…
When it comes to measuring structural stresses and load, every application is unique, and sometimes that means using a different solution. In some cases where strain gauges are applied, it can be advantageous or even necessary to use weldable strain gauges instead of chemical bonding the strain gauges…
The most common strain gauges used to quantify the state of stress on a test specimen’s surface, are uniaxial and rosette gauges. For accurate measurements of stress and strain, these uniaxial and rosette gauges are independently connected as a Wheatstone bridge in a 3-wire quarter-bridge or half-bridge arrangement….
Our iTestSystem customers who routinely acquire data with high channel counts and data from full-bridge transducers recently requested that we update the sensor auto-zero utility to improve test setup efficiency. In the latest version of iTestSystem, we updated the sensor auto-zero utility to include all channels that use…
When making strain measurements it is important to perform a shunt calibration both before and after the actual measurements are acquired. Shunt calibrations ensure accurate strain measurements by adjusting the sensitivity or gain of the data acquisition equipment to compensate for leadwire resistance and other scaling errors. iTestSystem…
