Microprecision Electronics has announced the MP300 switch series with an attached floater actuator for cost-effective liquid detection in industrial refrigeration and other process control applications. By adding a floating polypropylene ball mounted on a stainless-steel level actuator to a switch from the l V3-size MP300 switch series, Micro-precision designed a solution to determine when a specified liquid level is reached. Once activated, MP300 switches can trigger a signal as an input for a PLC, or directly switch power of up to 6 A. The ball has a 2-in. diameter, a working temperature of up to 210 °F, and withstand up to 250 °F for short periods of time. According to the company, exceptional chemical resistance makes it useful in liquids, from oils to coolants. Switches are mounted outside the liquid contents but feature a sealed, IP67 design. www.microprecision.us Microprecision Electronics
