Based on piezeresistive technology, WM120C Submersible Liquid Level Transmitter is designed for gauge (relative) pressure application in liquid level measurement. These level transmitters are made from 316L stainless steel with rigid and robust construction, cable with vent hose for submersible applications. WM120C liquid level transmitters provide amplified output signals such as 0~5 V or 4~20mA with an option of HART protocol. These transmitters can also be equipped with a 4½ digits LCD field display. WM120C is compact and easy installed. It can be applied directly into the water. The protection cap with a small hole not only protects the diaphragm, but also let the liquids contact the diaphragm freely. The exquisite sealing technology as well as good assembly techniques guarantee WM120C´s outstanding quality and performance. The product has a waterproof cable with vent hose which is designed for submersible applications. WM120C is designed with IP68 protection which is widely applied in petroleum, chemical industry, medicine, metallurgy, hydrology exploration etc.
