Electric contact level gauge

The series of electric contact liquid level gauges are mainly used for water level measurement in boiler drums, high and low heaters, deaerators, evaporators, once-through boilers, starting separators, water tanks, etc. This device consists of a measuring cylinder and a secondary instrument. It uses a digital display and a steam red, water and green two-color light-emitting diode to display the liquid level. The electrode of the measuring cylinder has a small impedance to the cylinder in water and a large impedance to the cylinder in steam. As the water level changes, the number of electrodes in the water changes, which is converted into a change in resistance value and transmitted to the secondary instrument, thereby realizing water level display, alarm, protection, interlocking and other functions.
Product Features of Electric Contact Level Gauge
① It has a flashing and audible alarm function.
② It has signal output, can be connected to the system, and has a protection interlock output function.
③ It has self-power supply function and can continue to work for hours after power failure.
④ There are three buttons on the instrument, an alarm, silencer and sewage discharge button and a detection button.
