The noncontact sensor works with plastic tubes, rubber hoses, and small glass or plastic pipes. It is designed to measure high-dielectric fluids such as those having a water base. Installation consists of snapping the device on the tube at the level that needs monitoring. The standard TLS 100 sensor fits tube and hose diameters of 3/8 and 7/ 16 in.

Aluminum mounting clips serve as sensing electrodes, which increase the adjustable sensitivity range. The sensor provides a transistor alarm output or switched control output up to 1 A. The sensor has an IP65-rated plastic housing, measures 2.33 1.63 0.8 in., and works in media with temperatures ranging from 32 to 194°F. Applications include pharmaceutical manufacturing, food processing, chemical mixing, and detergent dispensing, as well as to protect pumps from running dry when fluids fall below preset values.
