Optomax Industrial Range of Liquid Level Switches

The Optomax Industrial range of liquid level switches were designed to offer industrial supply voltages and outputs that can directly drive higher power 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).

Available in two chemically resistant housing materials, Polysulfone, the standard choice for most applications, or Trogamid, which is typically used in food and beverage applications.

The Optomax Industrial range of liquid level switches are built to the highest quality standards and are not only highly accurate but they also have a good lifespan.
