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, long-term stability and reliability are required.
The instrument is suited for in- and outdoor application. A tempered piezo-ceramic 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.
