Strain Gauge Bridge Completion Modules

Today, most high-end data acquisition equipment manufacturers provide signal conditioning options for collecting data from single strain gauges.  Signal conditioning for strain gauges usually includes circuitry for bridge excitation voltage, quarter and half bridge completion arrangements, and shunt calibration. What we offer Are you looking for expert assistance with accurately measuring stress and strain? or, […]

Testing Services Team Annual Safety Training

I want to congratulate my colleague Ryan “RJ” Matthews on a job well done as he recently administered ITM’s annual safety training.  RJ did an excellent job presenting the material and addressing questions. His efforts will certainly help us stay focused on our vigilance toward workplace hazards. For strain gauging or test services, contact Ryan […]

Accelerometers for Rotating Machinery Vibration Measurements

Choosing an accelerometer for rotating machinery vibration measurements can be a daunting task since there are so many options available. This blog outlines the characteristics you should consider when choosing a piezoelectric single axis accelerometer for general purpose vibration measurements and presents some accelerometers to consider. Characteristics of a General Purpose Accelerometer When measuring vibration […]

How Do I Collect Vibration Data with iTestSystem and a cDAQ?

 Our test engineers collect vibration data on rotating machinery using four basic tools.  We use a Laptop computer with iTestSystem software to stream accelerometer and rotational/speed pulse sensor data from a National Instruments cDAQ equipped with vibration and voltage input modules.  The video above shows how to collect vibration data using iTestSystem and a […]

Wireless Strain Measurements with iTestSystem, LabVIEW, and Arduino

 On a recent project, one of our engineers needed to measure structural strain at several locations on mobile lifting equipment while in operation. Since the strain measurements were distributed and mobile, a wireless internet of things (IOT) solution was required. This blog describes the steps and tools we used to integrate our solution into […]

Another Successful Condition Monitoring System Installation

 Last week our team successfully and safely installed another Boiler Monitoring System (BMS).  This system, a Sootblower Fouling Detection (SFD) system, monitors structural and vibration sensors that quantify the boiler’s response to sootblower operations. The SFD system analyzes the boiler response data and outputs Key Performance Indicators (KPIs) such as fouling level, sootblower efficiency, […]
