Pressure sensors
Pressure transmitters without casing (voltage 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, 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, silicone glue (p
r
≤
10 bar) or epoxy glue (p
r
> 10 bar).
Voltage output proportional to pressure: 0.5 ... 4.5 V
Reverse supply voltage protection
RoHS-compatible, halogen-free
Without casing (protection IP00)
Dimensional drawings
Type KC for gauge pressure
(M5 thread connection)
Type TH for absolute pressure
(M5 thread connection)
All dimensions in mm
