Gauge pressure range from -1 0 bar to 0 60 bar. Absolute pressure range from 0 1 bar to 0 16 bar Pressure transmitters from this series are suitable for a wide variety of measuring tasks in the fields of: Process engineering Process technology Environmental engineering Construction and mode of operation The pressure being measured acts directly on the ceramic diaphragm, causing it to distort. That in turn alters the resistance of the strain gauge on the rear of the diaphragm in proportion to the level of distortion. Electronics in the pressure transmitter housing convert the change in resistance into standard electrical signals. Function diagram Features Configurable Robust housing design High accuracy Low hysteresis Parameterisation The device is supplied as defined in the ordering code. Nevertheless, to optimise performance in line with prevailing process conditions it is also possible to configure the pressure transmitter on-site via the connection cables. To do so you will require a PC as well as the programming adapter EU13, available as an accessory. Pos Description 1 Ceramic sensor 2 Electronics 3 Power Supply Output signal
