The DS 210 low pressure switch, indicator and sensor utilises an exposed silicon diaphragm for extra sensitivity at low pressures whilst maintaining a high accuracy for the analogue output of 0.35% full scale for ranges above 100 mbar and 0.5% full scale for ranges below 100 mbar.
The digital LED display can be configured by the user to display in any pressure units and the 1 or 2 switch contacts can be set to trigger at any pressure within the range. The DS230 combined low pressure switch, readout and sensor is externally powered via a cable or connector exiting from the top of the instrument which is also used for the analogue output if specified.
