GENERAL
MPT40
PRESSURE TRANSDUCER
 Micron's Model
MPT40 is a flush mountable, miniature, low cost, general use pressure/temperature
transducer. This transducer is made of corrosive resistant titanium
(6AL4V). It utilizes high reliability bulk type semiconductor strain
gages and temperature sensors bonded directly to the inside surface
of the machined diaphragm.
Titanium hermetic headers permit offering the MPT40 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.
