Pressure sensors
Pressure transmitters with casing (current output)
CAU-T series
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 (pr ≤ 10 bar) or epoxy glue (pr > 10 bar).
ꢀ 2-wire current output proportional to pressure: 4 ... 20 mA
ꢀ Reverse supply voltage protection
ꢀ RoHS-compatible, halogen-free
ꢀ Compact stainless steel casing (protection IP65) with G1/8" thread
