ITM adds NI-9253 Compatibility to iTestSystem

This week we added another module to the iTestSystem compatibility list.Ā  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.Ā  National Instruments (NI) recently introduced a new C-Series current module, the NI-9253, that was a perfect fit for this application. […]

Strain Gauge Installations for Field Testing

Our engineers and technicians have epoxied, soldered and spot welded strain gauges for applications ranging from high temperature exhaust systems to miniature load cell measurements. Every application requires a unique understanding of the strain measurement requirements including installation environment. If the strain gauge installation is to survive in the field you must plan for the […]

Roving Accelerometer Impact Tests with iTestSystem

In order to prevent or troubleshoot structural vibration problems, it is important to characterize a structureā€™s dynamic behavior using both experimental and Finite Element Analysis (FEA) technologies.Ā  OneĀ method usedĀ to identify a structure’s vibration modes is to perform a roving accelerometer or roving hammer impact test.Ā Ā In anĀ impact test,Ā engineers measure the response of a structureĀ from anĀ impulseĀ delivered byĀ a […]
