Electric contact level gauge

HJ-UDZ series of electrical contacts is mainly used for boiler drum level gauge, the level of the heater, deaerator, evaporator, a once-through boiler starter separator, water tanks and other water level measurements. The device consists of measuring cylinder and the secondary instrument, the use of digital display and red vapor, liquid water green two-color LED display. Electrodes measuring tube in the water to small impedance cylinder in steam in large impedance of the cylinder. As the water level changes, the number of electrodes in the water change, convert change in resistance value is transferred to the secondary instrument to achieve the level of display, alarm, interlock protection functions.
