Madison Company has announced the availability of its O Series of optical single-point liquid level detection switches for use in non-coating liquids. These units provide accurate, repeatable switching point detection with no moving parts. They operate with a phototransistor that provides a digital output indicating the presence or absence of liquid. The phototransistor is housed in the sensor tip, providing highly reliable performance in a compact design that is ideal for limited-space applications.
Madison offers the O Series switches in over 70 standard models, with both metal and plastic housings and various mounting configurations, as well as wire and supply current options. All are designed for easy installation and maintenance-free performance. Custom-engineered designs may also be requested by using Madison’s O Series Specification Sheet.
