Its silicon sensor includes a 5-point NIST certificate. It is used for automotive and aerospace testing and OEM test-stand integration.
OMEGA piezoresistive pressure transducers have a proven record in high performance commercial and aerospace applications for over 25 years. The PX409 Series uses a highly stable silicon wafer which is micro-machined to precision tolerances and then has silicon strain gauges molecularly embedded into it.
At our state-of-the-art facilities, automated test equipment performs pressure and temperature cycling on 100% of the PX409 transducers. The transducers are then calibrated using extremely high accuracy equipment and a 5-point NIST traceable calibration certificate that is included with each transducer.
