Coal RF admittance level switch parameters

RF admittance level switch HL01-XXMZ01ZY31(Parameter: DC24V, 500mm) Threaded installation, widely used in industries such as metallurgy, power, coal, cement, and ports, is an important protective equipment for belt conveyors. Radio frequency admittance level switch, admittance level switch, and radio frequency admittance level meter are level control instruments designed based on absorbing the technology and functions of similar foreign products. All of its highly reliable sensors and stable circuit modules are made of imported components.shootThe frequency admittance level controller is currently a cutting-edge alternative product for international level controllers, which has been widely used in Europe, America, and Japan. Domestic users are also using it to replace old products. It can detect all materials without being affected by changes in parameters such as density, particle size, chemical composition, sedimentation viscosity, and conductivity. Widely used for controlling various materials such as liquids, powders, slurries, solids, etc.

Working principle of RF admittance level switch:

The RF admittance level controller is developed by our company based on the introduction and research of RF technology. It is an anti adhesion, more reliable, and widely applicable level controller: a high-frequency radio wave is applied to the probe. When the position of the material changes, the admittance value of the probe, container wall, and the measured material of the instrument changes accordingly. This change is detected by the circuit and converted into relevant signal outputs for remote control or alarm use. The circuit design of the instrument (utilizing the principle of equipotential) can eliminate the influence of material accumulation on the measurement circuit, thereby accurately reflecting the actual level of the material instead of adhering to the material accumulation on the probe.

Working principle of anti rotation level switch:

The anti rotation level switch uses a synchronous micro motor to drive the detection blades to rotate at a speed of one rotation per minute after deceleration. When the level of the tested material rises and the rotation of the blades is hindered, the detection mechanism generates rotational displacement around the main shaft. This displacement first activates a micro switch, emitting a material level signal. Subsequently, another micro switch is activated to cut off the power supply to the motor, causing it to stop running. As long as the material level remains unchanged, this state will continue indefinitely.

When the material level drops and the detection blade loses its obstruction, the detection mechanism relies on the spring tension to restore it to its original state. Firstly, a micro switch is activated to turn on the motor power and rotate it once. Then, another micro switch sends out a no material level signal. As long as there is no material blocking the rotation of the detection blade, this state will continue.

Key Features:

Strong universality: widely used in various occasions, including dust, particles, powders, liquids, viscous, conductive, and non-conductive materials.

Anti adhesion: The circuit design of * allows the measurement circuit to ignore the accumulation of materials on the probe and automatically calibrate.

Detached probe: The probe and controller can be separated without cable connection, making installation and removal easy and not affecting on-site work.

Powerful function: The output contact capacity is large, and there is an indicator light to display the working status. The impact of material fluctuations can be eliminated within 0-30 seconds.

Installation:

When selecting measuring points at the top of the warehouse, direct impact of materials on the level switch probe should be avoided. Therefore, the horizontal distance between the measuring point and the feeding port should be ≥ 1m. If there is a throwing angle during feeding, it should be avoided to directly face the throwing direction.

If applied to high material level measurement, in order to be able to measure the high point of the material level, the selection of measuring points should not be too far away from the feeding port.

3. Install flange pipes at the selected measuring points according to the installation diagram of the material level switch, and the flange plane should be horizontal.

4. Remove the material level switch, spiral the built-in flange upwards, connect the probe rod to the switch, and tighten the stop screw.

5. Insert the switch into the installation flange pipe and tighten the flange with 4 M 16 * 50 bolts.

6. Connect the wires according to the circuit diagram and turn on the power.
