Engineering Data Acquisition Tools: cDAQ-9189

When our engineers go on the road to troubleshoot structural component failures or machine vibration problems, they grab their laptop with iTestSystem installed and Pelican case containing an NI CompactDAQ (cDAQ) chassis and an assortment of C-Series modules, accelerometers, and strain gauges. The cDAQ chassis that they typically use is a cDAQ-9189 ethernet chassis. The […]

Clinker Detection System

A proprietary monitoring technology developed by Integrated Test & Measurement is introducing a brand new approach to address “fouling” in coal-fired power plants as well as the pulp and paper industry.

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. Sometimes you may need to view or collect data from a single strain gauge using a […]

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 […]

General Purpose 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 cDAQ.
