Electrical measuring cylinder, liquid level meter level meter poleelectrode, manufacturer

Electric contact liquid level monitor is composed of a measuring cylinder,ultra pure ceramic electrodes, display instrument consisting of electric contact liquid level measurement, display and control instrument. Divided into common type, intelligent type, hanging type. It adopts dual colorLED display simulation on steam (red) and water (green), clearly indicate the level in the POSTTTION in the container, and has alarm, output function.

Electric contact liquid level monitor has the advantages of simple structure, intuitive display, reliable operation, small amount of repair,judgment and easy troubleshooting etc.. It uses the electrical signal transmission, not only a small delay variation, and no mechanical transmission generated and calibration error, without the need for error calculation and adjustment. Electrical contact level gauge has the advantages of the most prominent, is to adapt to variable parameteroperation of boiler, the boiler stop parameter varying operating conditions, instrument can accurately display the water level in the control room.

Liquid level measurement and control electric contact liquid level monitoris suitable for conductive liquid. Mainly used for monitoring of boiler drum water level, high and low pressure heater, a deaerator, evaporator,condenser, separator and other water tank liquid level measurement ofonce through boiler startup. But not suitable for combustible and explosive occasions.

Electric contact liquid level monitor main features:

The 1 electric contact measurement using AC power supply, effectivelyprolong the electrode life, avoiding the user frequent replacement ofelectrode troubles.

2 meter display part adopts analog display and digital display two waysat the same time, intuitively displayed lifting of water level.

3 has liquid level limit alarm function, the alarm can be set arbitrarilyaccording to user needs.

The 4 alarm control logic judging function, can effectively prevent thefalse water level alarm.

5 according to the power system disturbance characteristics, especiallythe anti-jamming measures.

6 with self power supply function, after the power is turned off can automatically switch to the machine battery self powered up to several hours, ensure that the power meter can normal indication, alarm level value (option).

7 has the function of self checking, the instrument panel for rapid detection of fault detection button two meter.

8 the instrument panel setting emission button, to eliminate the measuring cylinder discharge caused by lower false alarm and false action.

9 implementation of the water resistance automatic judgment, tracking,set the maximum water resistance and minimum steam resistance, the instrument can automatically judge, trace vapor resistance changes in the range of (intelligent).

10 the realization of human-computer dialogue, through panel keyoperation can be set for each scale value and any alarm set point value,and according to the scale values to facilitate the replacement of staff,general

The characteristics of strong, to overcome the old instruments are not interchangeable, standby specification requirements and other disadvantages (intelligent).

11 in order to effectively prevent the misoperation level protectionmechanism, the instrument can be added instrument startup delay work function.

12 can be equipped with 0 ~ 10mA or 4mA ~ 20mA current output function, easy to connect with other systems.

13, the lower limit of two groups with the relay normally open and normally closed contacts for outdoor use, the lower limit on the specialcan be equipped with three groups of normally open contacts.

14 wall mounted alarm contact down by 70 ° tilt installation, can effectively prevent the false water level alarm.

The 15 electrode with the test function, the instrument can be tested individually for each electrode, and can display the water resistance of every point (steam resistance) value (intelligent).

16 has strong fault tolerance, the intelligent level of recognition technology, to prompt the user for maintenance and replacement of the electrode (intelligent).
