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):

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

2-wire current output proportional to pressure: 4 ... 20 mA
