This new level sensor can even detect process water
The new sensor CombiLevel PLP70 (photo) automatically adapts to varied media and offers user-friendly process monitoring thanks to the large touch display. The PLP70 potentiometric level sensor is able to measure media of low minimum conductivity — down to 10 microsiemens (µS). This is well below conventional limits, and allows for use in media such as process water, the company says. The device has an IO-Link interface, and it allows accurate and reliable measurement for precise monitoring of filling levels in feeding containers and storage tanks. Thanks to the short response time (less than 100 ms), the PLP70 is ideal for highly dynamic processes like fast changing levels in filling lines. Applications include industrial (process tanks, cleaning and filter plants, water treatment installations, agricultural machinery) to hygienic (filling lines, storage and buffer tanks, process tanks, filter and cleaning facilities). The CombiLevel PLP70 with standard digital IO-Link interface and analog output was launched at drinktec (Munich, September 12–16). — Baumer Group, Frauenfeld, Switzerland
