Product Description

First, an overview
UDZ series electric contact water level meter, mainly used for boiler drum level, heater, deaerator, evaporator and boiler
Water level measurement of starting separator, water tank, etc.. The device is composed of a measuring cylinder and two instruments. Using digital display and Qi Hongshui
Green dual color LED display liquid level.
Two, the characteristics and technical parameters of the 1 Characteristics of the instrument:
With flash, sound alarm function.
4-20mA signal output, can be connected to the DCS system, with the protection of interlocking output function.
With self power supply function, can continue to work for 4 hours after power off.
The instrument is equipped with three buttons, a alarm button button, C silencing, B emission detection.
2 technical parameters:
The electric blow? Bartholomew 220V + 10%, 50Hz stem?

Four, working principle
The electric contact water level gauge is designed according to the difference between the water and the steam resistivity. The electrode of the measuring tube is small in water. The large impedance of the cylinder in steam.
With the change of water level, the number of electrodes in the water is changed. Converted to resistance? Files to seek and to sit tight steal banana 4 I dive, from the Commission Di sunburn is bad South allows to do. A lot of to sit tight.; (AQT) skirt Delta. Click to see a larger image
