DS 233 Differential Pressure Switch for Gases and Compressed Air in Compact Version Silicon Sensor accuracy according to IEC 60770: 0.35 % FSO Differential pressure Output signal The DS 233 is a differential pressure switch with digital display for non-aggressive gases and compressed air. Because of its compact and robust aluminium housing it is particularly suited for machine and plant engineering. Basic element of the DS 233 is a piezoresistive silicon pressure sensor, which features high accuracy and excellent long term stability. from 0 ... 6 mbar up to 0 ... 1000 mbar aluminium housing As standard the DS 233 offers a PNP contact and a rotatable display module with 4-digit LED display for representing the differential pressure. Optional up to two freely configurable contacts are available. rotatable and configurable display module Special characteristics suited for non-aggressive gases and compressed air Plant and machine engineering Optional versions Heating and air conditioning ► customer specific versions BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein
