Two, work principle:

ZW-ZDS series <strong> of magnetic suspension photoelectric double color level meter</strong> according to the principle of buoyancy and magnetic coupling principle. When measured in the container level lift, liquid level gauge leading tube float will lift, float within the magnet with a transfer to the scene display * box of high precision electronic sensor through magnetic coupling, triggering the corresponding digital circuit, the LED double color LED color conversion, no red liquid, liquid filled all green, red and green at the junction of the actual level is within the container, so as to achieve the level of the scene at a glance; installation instructions, limit switch to achieve level alarm and control, with the transmitter digital signal output for display and control.

Three, application:

ZW-ZDS series <strong> of magnetic suspension photoelectric double color liquid level gauge</strong> with limit switch, can achieve the level of upper and lower limit of alarm and control; selection of liquid level transmitter, the liquid level can be 4 ~ 20mADC analog signal into standard signal, realize remote detection, indication, record and control, and computer system for direct communication. This series of products are widely used in electric power, metallurgy, petroleum, chemical industry, environmental protection, marine, building and other industries in the production process, level measurement and control of various tower, tank and boiler equipment.

Four, main features:

1, simple design. Compact. Strong and reliable. Long life. No maintenance, can long indoors. Installation:

Scene 2, unique. Remote integrated structure, the industrial automation management becomes more easy and convenient;

3, a unique electronic luminous double color display, suitable for the application in the light dark places, night observation more eye-catching;

4, the unique imported mist astigmatism LED LED display effect, strong penetrability, clear bright, clear for industrial remote monitoring;

5, measurement display part, and the liquid level transmitter, the alarm switch in voltage, resistance completely isolated;

6, working pressure range, pressure from vacuum to 42MPa; corrosion resistance <2.5MPa;

7, wide working temperature range, suitable for -160~+530 from c;

8, widely used in strong corrosive, flammable, toxic, strong radiation, agitation, dirty liquid level measurement;

9, you can choose various types of magnetic limit switch, realize the liquid level automatic control or alarm;

10, you can choose various types of 4~20mADC liquid level transmitter, realize remote centralized measurement and control.

Five, technical parameters:

Eight, insulation:

Steam jacket and circulating water jacket, is leading an additional layer of cylinder tube in liquid, steam, circulating water or heat conducting oil circulation.

Vacuum jacketed pipe is led by adding a layer of vacuum tube in the liquid level, so that the measured medium and external insulation.

Double jacket, generally refers to a hot steam jacket to do a layer of vacuum jacket.

Electric heating system, is leading tube level in the winding electric tracing band to the heating medium.

Nine, the installation position:

Double color level meter display parts of the installation position can be arbitrarily changed:
