The LMT Series Sanitary Point-Level Sensor is designed to monitor the level of liquids, viscous media and powders in food and beverage processing tanks and pipes. The sensor can provide reliable level indication in storage tanks and protects pumps from run-dry conditions. Viscous media, such as ketchup and mayonnaise, tend to stick to a sensing face and cause unreliable level indication. The LMT sensor uses high frequency (MHz) capacitive spectrum profiling technology that enables the sensor to ignore foam and deposit build-up and differentiate between actual product in a tank or only residue. The LMT''s capacitive technology allows the sensor to detect measuring points at multiple frequencies which enables deeper penetration into the media. The LMT "sweeps" the frequency band of 50...200 MHz taking three measuring points: electromagnetic field damping, permittivity phase shift of the molecule polarization in the magnetic field, and the media conductivity in the electric field. An internal sensing algorithm processes these measurements to calculate the signal amplitude. The LMT sensor meets food and beverage sanitary requirements and features a PEEK sensing face with a food-grade surface finish. A 316 stainless steel body ensures chemical compatibility. A high protection rating of IP68/IP69K prevents liquid ingress. Laser-etched part numbers won’t deteriorate in high pressure cleanings.
