Liquid sensor type DRS-303 is designed for conducted liquid presence detection. Parameters of the detector have been fixed to allow detection of actual presence of liquid on its electrodes and to be resistant for low impedance conducted surfaces (eg. wet fingers). Additional reference electrode prevents detector against false signalling when
liquid covers its surface only. PUSH-PULL output gives an opportunity for connection either to devices equipped with direct or inverse logic inputs.
Wide range of supply voltage (12...30V DC) and operation temperatures (-40...+85°C) allow to use the sensor in most systems (eg. pump dry run detection, full tank detection etc.)
