GENERAL
Model
MP502 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.

Pressure on the diaphragm is applied through the hole in the 10-32 threaded nose which is converted to a signal directly proportional to the pressure.
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.

special temperature or pressure ranges and high-vibration
resistant options. Long term stability versions are
available
