Miniature Liquid Level Sensors
LEVEL SENSORS FEATURE MAGNETIC FLOATSA new line of compact liquid level sensors that are more reliable than mechanical switches and are an alternative to costly Hall effect sensors is being introduced by MEDER electronic.
MEDER LS-Series Liquid Level Sensors are made from corrosion-resistant materials and feature magnetic floats which activate reed switches when the liquid level rises or falls, as desired, and then provides an output signal. Requiring no external power, the magnetically operated hermetically-sealed proximity sensors can be remotely placed to isolate the reed switch electrically >1,000 VDC and mechanically, away from fluids.
Available in a variety of configurations, MEDER LS-Series Liquid Level Sensors can be made from polypropylene for use in water and dilute acids or polyamide for use in oil, petrol, and brake fluid. The reed sensors are offered in Form-A and Form-B types with various connector options. Applications include tank monitoring in household appliances, and a wide range of automotive, test, and measurement control technologies.
MEDER LS-Series Liquid Level Sensors are priced according to version and quantity. Literature is available upon request.
