Hydrostatic pressure transmitter FRIPRO P21

Technical Description

Hydrostatic precision pressure transmitter with ceramic measuring cell, front flush. Suitable for drinking, food-safe, small and robust with various electrical and process connections. The device is a top quality product, that is, it corresponds to the generally very high technical standards in all technical details.

Typical application areas tested:

Continuous pressure measurement in open and closed containers and
Other technical closed systems in which a pressure monitoring or a pressure
   measurement is required, e.g. in technological systems of water technology,
   hydraulics and pneumatics.
