GENERAL
MPT402
DUAL PRESSURE AND TEMPERATURE TRANSMITTER
 Micron's
Model MPT402 is a miniature dual pressure and temperature 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.
The temperature is measured
from the inside surface of the diaphragm and is not pressure or
strain sensitive.
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. |
