- Scalable measuring range and analogue output
- Configurable mean value calculation, heating control,
energy saving mode and baud rate
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)
