For many structural engineers, the VTI Instruments EX1403 Precision Bridge and Strain Gauge Instrument from AMETEK Programmable Power is the go-to solution for complex test applications. One reason why is that it’s very easy to programmatically configure the built-in strain gauge excitation sources. So there’s no need to manually reconfigure hardware to make measurement changes. In addition, the VTI EX1403 can internally convert the voltage and current measurements to strain or resistance measurements.
Testing that requires the use of strain gages often consume large amounts of resources and effort to prepare for. One way to reduce the amount of time and energy spent configuring a test is to use sensors that support the Transducer Electronic Data Sheet (TEDS) interface. Many VTI measurement instruments support TEDS sensors including the EX1629 48-channel high-performance strain gage measurement instrument, EX1403 16-channel bridge/strain gage instrument, and the RX1024 24-channel bridge/strain gage instrument.
A jet engine is the very definition of “mission-critical.” A critical failure could cause a serious accident that endangers hundreds of lives. To prevent this from happening, manufacturers perform extensive testing on jet engine components, systems, and manufacturing processes.
Jet engine tests involve subjecting the unit under test to extreme temperatures, jets of water, simulated hail, severe vibration, and other harsh conditions. Sometimes test engineers even slam chicken carcasses against engines to simulate bird strikes. These tests can be very costly and take years to develop. Engineers must measure many different parameters during these tests, including temperature, flow, pressure, rotation, strain, and vibration.
