Wema Faeces Level Sensor 305 mm 240-30 Ohm

Product description:

The Wema S3H faeces level sensor with a length of 305 mm is a specialized resistive sensor designed for precise liquid level measurement in faeces tanks, most commonly used in recreational vehicles (motorhomes, caravans), boats, yachts, and special vehicle sanitation systems. The device operates on the principle of resistance change in the range of 240–30 Ohm, allowing compatibility with most standard liquid level indicators. The sensor is mounted vertically in the upper part of the tank, screwed into a prepared hole using a standard mounting flange, ensuring tightness and installation stability. The housing is made of materials resistant to the aggressive sewage environment, such as stainless steel and plastics, guaranteeing long service life even with intensive use. The sensor design minimizes the risk of clogging and allows easy cleaning. The product is compatible with liquid level monitoring systems from many manufacturers, and its 305 mm length allows use in tanks of medium depth. The Wema S3H sensor is widely used in the marine industry and commercial vehicles where reliability and resistance to harsh working conditions are crucial.
