WL420 Submersible Hydrostatic Level Transmitter 1 mH2O Cable 15 m The WL420 is a robust submersible hydrostatic level transmitter designed for continuous, reliable monitoring of liquid levels in wells, reservoirs, tanks, boreholes, and rivers. It operates on the principle of hydrostatic pressure, measuring the pressure exerted by the liquid column above it and transmitting a proportional 4-20mA signal. A key benefit is its construction with a 316L stainless steel diaphragm sensor, ensuring compatibility with raw water, chlorinated water, and most semi-aggressive liquids and oils. The integrated vented cable provides automatic atmospheric pressure compensation, guaranteeing accurate level measurement regardless of weather conditions. Available in multiple measurement ranges (1 to 100 mH?O) and customizable cable lengths (5 to 120 meters), the WL420 is IP68 rated for permanent submersion and features built-in protection against polarity reversal and current overload. Its loop-powered design simplifies installation and makes it ideal for integration with panel meters, data loggers, and PLC systems.
