Detects the presence/absence of almost any liquid type (oil or water-based) Housing material: Polysulfone Supply voltage (Vs): 4.5VDC to 15.4VDC Sensor Termination: 24AWG, 250mm PT FE wires, 8mm tinned Operating pressure: 7bar / 101psi maximum The Optomax Digital Liquid Level Switch is ideal for applications that require a small, low power sensing solution. The microcontroller based sensor is a solid state, incorporating an infrared LED and a phototransistor which are optically coupled by the tip when the sensor is in air. When the sensing tip is immersed in liquid, the infrared light from the Optomax Digital sensor emits, making the output state change. The sensor can detect the presence or absence of almost any liquid type; oil or water-based. It is insensitive to ambient light and is not affected by foam when in air or by small bubbles when in liquid. The TTL compatible push-pull output can sink and source up to 100mA at a supply voltage range of 4.5 to 15.4Vdc. Show more
