Versatile sensor switch

摘要

Sick (UK) has added to its industrial instrumentation product portfolio with a new compact optical level sensor switch for aqueous fluids. Designed for robust level monitoring of liquid media, the FDA-compliant MHF15 is suitable for a variety of applications, including tank level monitoring or dry running protection for pumps. The cost-effective plug-and- play solution, which requires no calibration and minimal maintenance, can be used fdr overfill protection and low level indication in tanks to monitor the presence or absence of liquids. A normally open or normally closed transistor output is provided for use as an input to control PLCs or relay modules.
