Description
Liquid sensor type BDRS300 is designed for conductive 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 conductive 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 adevices equipped with direct or inverse logic inputs. Wide range of supply voltage (12 – 30V DC) and operation temperatures (-40°C ÷ +85°C) allow to use the sensor in most systems (eg. pump dry run detection, full tank detection etc.) – case protection class IP 67, -detection of actual presence of liquid on electrodes – operation temperatures -40°C ÷ +85°C. – pump dry run detection, – full tank detection etc., – liquid level detection.
