Baro Transmitter
Baro Transmitter The baro transmitter measures the “absolute air pressure” of the
atmosphere at the site. It is designed for application in the field of
environmental protection, where high accuracy, quick responding behaviour,
longterm stability and reliability are required.
The instrument is suited for indoor- and field application. A tempered piezoceramic
sensor for absolute pressure is used, which is characterized by thermal and mechanical
stability.
The electric connection is done via an 8-pole terminal strip and a special screwed
cable gland with smoothing function for air pressure.
The following outputs are available:
1 x serial interface 1 x frequency output 1 x Analogue output (U/I)
Digitaler Barogeber
Digital Baro transmitter

Indicating measurement instrument with analogue output to determine the atmospheric pressure. An aneroid capsule with inductive displacement pickup serves as a sensor. The sensor signal is amplified electronically and displayed digitally on a LED- display. The current output is available for the connection of electronic recording and control instruments.

Baro Transmitter B-278-1/2 T

Baro transmitters measure the barometric ambient pressure and emit the measured value as an electrical voltage value. Owing to its low current consumption, It is particularly suitable for use in combination with data loggers. To be mounted preferably in data logger systems.
