Madison Company offers an extensive line of standard and custom optical liquid level sensors for use in clean liquids. These compact optical sensors are ideal to switch digital outputs or small switched electrical loads and can be used as an optical sensor in single-point detection switch systems to detect the presence or absence of a liquid level. Highly accurate liquid switch points in a small package!
These compact optical switches incorporate a phototransistor that provides a switch output indicating the presence or absence of liquid. The Polysulphone or Crystal sensor tip houses the phototransistor in a form that provides highly reliable and repeatable performance in compact sensor designs.
Optical sensor housings are offered in both metal and plastic with various mounting configurations and sensor output options. Choose from our standard optical sensor part numbers, and Madison Company will provide you with a very cost-effective solution for those level indication applications where high reliability, ease of installation and maintenance-free performance are desired. Our optical sensors are also available with custom configurations, so contact your sales associate for assistance today!
