DYC1 Type Baro Transmitter
The baro transmitter measures the "absolute air pressure" of the atmosphere at the location.
It is designed for application in the field of environmental protection, where high accuracy, quick responding behavior, long-term sturdiness and reliability are required.
The instrument is suited for indoor- and outdoor application.
In the baro transmitter a tempered, piezo-ceramic absolute-pressure-sensor is used, that features excellent thermal and mechanical sturdiness.
