MP40 Pressure Transducer
mV Pressure Transducer Flush Mount
Introduction
Piezo-Metrics' Model MP40 is a flush mountable, miniature, low cost, general use pressure transducers. These transducers are made of corrosive resistant titanium (6AL4V). They utilize high reliability bulk type semiconductor strain gages bonded directly to the inside surface of the machined diaphragm.
Titanium hermetic headers permit offering the MP40 series with absolute or sealed reference options. The hermetic header is located just behind the strain gage diaphragm section of the sensor. Sealing the sensitive gages to an inert environment dramatically increases stability and reliability. Long term stability versions are available. High vibration options are also available.
