GENERAL
MPT502
PRESSURE TRANSMITTER
 Micron's
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.
Consult the factory
for special temperature or pressure ranges and high-vibration resistant
options. Long term stability versions are available.
