New Optical Water /Oil/ Chemical Liquid Level Switches LLG Series

New Optical Water /Oil/ Chemical Liquid Level Switches LLG Series   Descriptions: The Optomax Industrial Glass range of liquid level switches can operate in aggressive environments due to their stainless steel and glass construction while offering industrial supply voltages and outputs that can directly drive loads.   The microcontroller based sensor is solid state, incorporating an infra-red LED and phototransistor which are optically coupled by the tip when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red light escapes making the output change state. 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.   A range of N and P type output configurations can sink or source up to 1A at supply voltage ranges from 4.5 to 15.4Vdc or 8 to 30Vdc and can be configured to output a high or low signal in either a wet or dry state. Options for connecting to inductive loads or digital interfaces are also available.   With housing threads suitable for external sensor mounting and for use in two operating temperature ranges; Standard (-25 to 80°C) or Extended (-40 to 125°C). New Optical Water /Oil/ Chemical Liquid Level Switches LLG Series FEATURES Reverse polarity, ESD and transient over-voltage protected Wide supply voltage ranges N and P type output configurations, capable of sinking or sourcing up to 1A, can directly drive loads Standard and extended temperature ranges available Stainless steel housing with glass sensing tip Thread options for external mounting Very high operating pressure BENEFITS Solid state so no moving parts to cause unreliability Small in size so they can be installed in applications where space is limited Can detect tiny amounts of liquid when positioned correctly, ideal for leak detection Fast response time Repeatable switching point Built-in output delays available on request for applications where sloshing causes intermittent switching Very robust construction permitting use in a wide range of demanding applications Compatible with most fluids and chemicals
