Barometric transmitters are produced with standard range 80 ÷ 120 kPa.

At the customer´s wish it is possible to secure a metrological verification of the transmitters at an accredited Calibration Service Centre.

Instructions for use

Before the transmitter is connected to the pressure circuit it is necessary to check whether the measured pressure corresponds with the nominal range of the transmitter. Even a short-time overload over the maximum permissible overpressure can cause destruction of the measuring membrane!
