Detects the presence and absence of liquid by loss of infra red signal refracted into liquid Optical Liquid Level Switches  Detect almost any liquid: oil or water based  Fast & reliable detection with a very small amount of liquid  Intelligent switching behaviour to work in different environments  Low cost optical technology  Designed to replace competitor sockets  Ability to rapid prototype with customisation for electronics, switching behaviour, environmental sealing and terminating cables/connectors  Wide variety of power-supply, mechanical format and output options

How do Liquid Level Switches Work? In Air: Infra-red light is reflected back to the detector In Liquid: Infra-red light is refracted out of the cone leaving less energy to reach the detector No moving parts to fail - Designed to fit into solid state small spaces (only the tip has to Electronics suited to be in contact) directly drive and switch equipment The amount of received light is measured to determine if the sensor is in air or liquid
