Small High-temperature Pressure Transducer with built-in amplifier PWFA-PA

The PWFA-PA is a M8 bolt-shaped flush diaphragm pressure transducer.  It employs strain gauges as sensing element and is equipped with a built-in strain amplifier.  Since the PWFA-PA is small sized and can be used for dynamic measurement in high temperature ranges, it is most suited to in-vehicle measurement of hydraulic oil pressure of engine, motor, transmission, oil pump and so on.  A compact in-vehicle measurement system becomes possible because there is no need of combining an external amplifier.  Its shape of M8 hexagonal bolt enables easy installation in a thread hole.

Protection ratings : IP 65 equivalent
