Switch Simplifies Liquid Detection

Employing an attached floating actuator, the MP300 switch series promises easy, cost-effective liquid detection in industrial refrigeration and other process control applications. Adding a floating polypropylene ball mounted on a stainless steel level actuator determines when liquids reach a specific level. Once the switch activates, it can trigger an input signal for a PLC or directly switch power levels up to 6A. The floating ball measures 2” in diameter and specifies a working temperature up to 210°F, withstanding up to 250°F for short periods of time. The switch mounts outside the liquid, yet features an IP67 design, and is configurable as a changeover switch or with a NO or NC circuit. MICROPRECISION ELECTRONICS INC., Minneapolis, MN.
