Important notes at the end of this document.
Description
The transmitters are based on piezoresistive silicon pressure sensors
from our own clean room.
The T-series electronic compensates nonlinearity and temperature
errors and supplies a precise calibrated output signal with a high
immunity against electromagnetic influences (EMI).
Features
Piezoresistive MEMS technology
Measured media (absolute pressure):
Air, non-aggressive gases (gas humidity 0 ... 85% r.h., without dew)
Unsuitable for substances which react with glass, silicon, gold,
aluminum, stainless steel, NBR, silicone glue or silicone gel.
Measured media (gauge pressure):
Air, non-aggressive gases (gas humidity 0 ... 100% r.h.)
and non-aggressive fluids.
Unsuitable for substances which react with glass, silicon, stainless
steel, NBR, silicone glue (p
