The measuring range runs from 0 to 50 mbar. The measuring principle used registers even tiny pressure differences with great accuracy. The sensor is extremely safe against overloads up to 750 mbar. One 4 … 20 mA analogue output and two relay outputs are available for the output of signals. The ‘easy to operate’ electronics offer a large range of settings, which means that the relays, their time delay, the hysteresis as well as the analogue signal are freely programmable. A four-digit LED display provides ‘on the spot’ direct information.
