Pressure transmitters for PCB mounting (voltage output)
AC-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, aluminum,
ceramics, polybutylene terephthalate, 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
RoHS-compatible, halogen-free
Dual-in-line package for PCB mounting
Dimensional drawings
Type LN for absolute pressure
(4.8 mm tube fitting)
Type KD for gauge pressure
(4.8 mm tube fitting)
Type KC for gauge pressure
(M5 thread connection)
All dimensions in mm
