Pressure Transmitter

MP402

Introduction

Piezo-Metrics' Model MP402 is a miniature, low cost, general use pressure sensor that automatically compensates for line resistance and power supply changes. This transducer is made of corrosive resistant titanium (6AL4V) and utilizes high reliability bulk type semiconductor strain gages bonded directly to the inside surface of the machined diaphragm.
Absolute or sealed reference sensors are available as an option. The hermetic header is located just behind the strain gage diaphragm section of the sensor, sealing the sensitive gages to an inert environment which dramatically increases stability and reliability. Consult the factory for special temperature or pressure ranges and high-vibration resistant options. Long term stability versions are available.
