ZW-UZK series Length adjustable rotary type level switch <strong> (threaded)</strong> with special seal design, with two layers of dust, and a clutch device to protect the motor, reliable work, internal the advantages of simple structure, convenient use and maintenance, simple torque adjustment, reliable performance, no torque loss is not affected by temperature, humidity, adhesion effect. Can be used for the measurement of solid particles and dust, suitable for the level of detection of dust particles and other particles with diameter less than the free flow of 10mm.The switch can be installed in the cabinet, the cellar and the shaft, can also be applied to control the filling level and control empty, it can prevent overfilling.

Two, work principle:

The ZW-UZK series of <strong> adjustable length type rotary level switch (threaded)</strong> working principle is the use of permanent magnet motor drives the rotating blades when the detected material rises to leaf position, leaf rotation is blocked, the resistance to the terminal box detection device, detection device is a switch signal output, and cut off the blade stops rotating power.

When material falls, blade resistance disappears, the detection device depends on the tension of the spring back to its original state, the spring tension adjustment of different material proportion, the proportion of large adjustment of spring tension to strong or strong Zui, otherwise adjust to weak or weak zui.

Three, application:

The ZW-UZK series of <strong> adjustable length type rotary level switch (threaded)</strong> for detection of solid materials (powder, granular) level of material field control device, its unique sealing design, strong overload protection ability and easy installation, which is widely used in cement, metallurgy, coal, grain, feed, iron and steel, power plants and other industries, especially in the conductive material and material properties (state, humidity, dielectric constant, density etc.) often change, dust and other materials limit alarm application performance, can be used for monitoring the level of material of solid material.

Fourth, the main features:

1, full closed, the house can be used;

2, the unique design of the oil seal can prevent dust infiltration along the axis;

3, the torque is stable and reliable, cutting torque can be adjusted;

4, lightweight, easy to install;

5, leaves under heavy load, the motor rotation mechanism will automatically slip, protection from damage;

6, do not have from the tank on the whole group can be easily removed, check and repair the internal parts.

Five, technical parameters:

1, power: 220VAC/110VAC/24VAC 50Hz/60Hz;

2, power: 3W;

3, contact capacity: 8A /250VAC SPDT;

4, working temperature: -10~80 degrees (special customized Zui up to 400 DEG C, imported up to 1000 DEG C);

5, blade speed: counter clockwise 1rpm;

6, torque: 1N.m;

7, the proportion of suitable material: more than 0.4g/cm3;

8, protection grade: IP65;

9, blade material: SUS304;

10, outlet: M20 * 1.5.

Sixth, torque adjustment:

1, according to the detected material density is different, need to adjust the tension torsion spring, torsion spring tension to the strong Zui proportion is large, and weak to.

2, do not arbitrarily change the torsion spring, so as to avoid misoperation.

Seventh, installation requirements:

1, before the installation, please confirm whether the supply voltage is above consistent with logo.

A switch should be installed in the inlet to avoid 2, impeding, when cannot avoid installation of a protective barrier, to protect the blade from the material impact.

3, the level of installation, wiring box line inlet should be vertical downward, cable fixing nuts must be locked, if the conditions can add fangyuzhao etc..

4, confirm the installation level before or vertical installation.

5, the level of the installation of blade and the level was down 10 to 20O angle installation, in order to reduce the impact of the material. 6, according to the different detecting material density, need to adjust the tension of the torsion spring, torsion spring tension to the strong Zui proportion is large, and weak to.

7, do not arbitrarily change the torsion spring, so as to avoid misoperation.

The eight type of encoding:

Nine, design selection and ordering information:

1, please indicate the measured medium, density, size, pressure, temperature, height of bin bin;

2, the installation can be installed lateral or vertical installation. High range vertical installation, the user can according to measure the depth of soft sleeve (applicable to order extended 1 meters above the range);

3, detection of blade specifications, the factory is generally supporting materials according to the proportion of sand. If the measured medium is 4, lighter weight should use larger leaves (please specify);

5, the medium temperature is 80-300 degrees centigrade, please choose the temperature type (please specify when ordering);

6, explosive dust (such as flour processing and storage), please choose the explosion-proof type (the installation.).
