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…
Whether manufacturing vehicles, mining natural resources or operating machinery on a construction site, a single common factor can bring your operation and productivity to an absolute halt. That factor is noise. In a world where precision and performance rule, measuring and controlling sound levels can be crucial to…
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…
Do you need software and National Instruments (NI) C-Series hardware to fulfill your testing requirements? During this uncertain time, Integrated Test & Measurement (ITM) is here to support you. We offer various C-Series voltage, strain, vibration, and temperature modules for rent that can be easily configured in our…
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….
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…
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…
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…
This week we added another module to the iTestSystem compatibility list. One of our iTestSystem users recently needed to collect data from thirty-two (32), 4 to 20 mA current sensors along with their vibration measurements. National Instruments (NI) recently introduced a new C-Series current module, the NI-9253, that…
The FieldDAQ™ FD-11634 sound and vibration input module from National Instruments (NI) can now be used with the latest version of iTestSystem for your data collection needs. The FD-11634 is similar to the NI-9234, NI-9232, NI-9231, and NI-9230 cDAQ dynamic input modules and can be used with IEPE…
While iTestSystem is designed to collect data from specific sensor types like strain, voltage, current, and accel; custom signal types such as pressure, displacement, and force can also be configured by utilizing the Custom Scale functionality during the channel creation process. For example, manufacturers often need to measure…
