The controller adopts the principle of electromechanical level control and measures the material level in contact. When there is no material in the blade part of the silo, the level indicator is powered on, the indicator light is on, and the blade rotates counterclockwise; When there is material in the blade part of the silo, the rotation of the blade is blocked, and the control signal is converted, then the power supply of the level indicator motor is disconnected. This state is maintained until there is no material in the blade part, and the level indicator automatically resets. The motor power is turned on, the indicator light is on, and the blade starts to rotate, and the control signal is switched.

1. Using contact measurement, the results are true, accurate, and reliable; It can be installed horizontally, diagonally, and vertically, making it easy to install and use.

2. Anti interference, ready to use: Due to the absence of complex electronic components and amplification circuits inside, it is not affected by any electromagnetic wave interference and can be used for a long time without any debugging or maintenance after installation.

3. Super strong anti shake performance design: Even when materials flow, no wrong signals will be emitted.

4. Material level display function: Using long-life and high brightness indicator lights, the material level display is intuitive and convenient.

5. Dual protection function: Overload protection function prevents the blades from being damaged by excessive external forces and the motor; The automatic protection function prevents the level indicator from working when the rotation of the material blades in the silo is obstructed, protecting the motor and effectively extending its service life.

6. Excellent measurement reproducibility and adaptability to environmental conditions: i.e. not affected by changes in material particle size, shape, specific gravity, medium, scale, adhesion, temperature, humidity, dust concentration, etc.

7. Super dust-proof sealing performance, even under a pressure of 1MPa, dust cannot enter.

8. Seismic resistance and anti loosening structure design effectively prevent component loosening and slippage; Made of high-quality stainless steel material, it has excellent corrosion resistance and wear resistance.

9. Low price, excellent cost-effectiveness.

Product Features
1. Strong universality: widely used for the detection of various material media, including fly ash, particles, powders, liquids, viscous, conductive, and non-conductive materials; It can meet the measurement requirements of different temperatures and pressures, with high temperatures up to 800 ℃ and high pressures up to 5MPA; Can be used in harsh environments such as corrosion and impact.
2. Anti adhesion: The unique circuit design and sensor structure make the measurement ignore the hanging material on the probe and automatically correct it, without the need for regular cleaning, avoiding false measurement and false signal. (Anti hanging material)
3. Maintenance free: There are no movable parts during the measurement process, and there is no mechanical component damage, so no maintenance is required.
4. Powerful function: The output contact capacity is large, and there is a status indicator light to display the working status. The 0 and 30 second delay can eliminate the influence of material fluctuations.
5. Anti interference: contact measurement, with strong anti-interference ability, can overcome the influence of steam, foam and agitation on measurement.
6. Power outage protection: normally open or normally closed (can be switched on-site).
7. Accurate and reliable: Diversified measurement quantities make measurements more accurate, measurement is not affected by environmental changes, high stability, and long service life.

Product Application
1. Conductive and insulating liquids: chemical, oilfield, water and sewage treatment industries, etc
2. Conductive and insulating pastes: industries such as papermaking, pharmaceuticals, water and wastewater treatment, etc
3. Powder, ash, powder: power plants, metallurgy, cement and other industries

4. Particles, coal, grain: power plants, metallurgy, grain and other industries

Installation method.
1. Measure the liquid level of bucket shaped tanks using rod or cable probes:

Note: The probe rod or cable should avoid the opening and feeding port, and the probe rod or cable should be parallel to the warehouse wall. The distance between the warehouse wall should be greater than 200mm.
2. Measure the liquid level of a horizontal tank using a coaxial probe:

Note: Non barrel shaped tanks and non-metallic wall tanks can be measured using coaxial probes.
3. Measure the liquid level of a spherical tank using a connector:

Note: Spherical tanks and other irregularly shaped tanks can be measured using connectors.
4. Use heavy-duty cable to probe the material level of powder or fine particle silos:

Note: The probe should avoid the feeding port. When the warehouse wall is made of concrete, the grounding terminal of the sensor housing should be reliably connected to the concrete reinforcement with a wire.

Installation requirements:
1. The RF admittance switch can be installed vertically or horizontally.
2. During installation, it is necessary to ensure that the center probe and shielding layer of the sensor are not in contact with the container wall (or installation pipe), have good insulation, the installation thread is firmly connected to the container wall, the electrical connection is good, and the shielding layer of the probe should enter the interior of the container.
3. For occasions with mixing, the probe needs to be supported or anchored (the fixed end should be insulated from the probe). The instrument inlet for horizontal installation must be downward, and the explosion-proof pipe for vertical installation must be bottom of the drainage outlet of the inlet to prevent water accumulation in the explosion-proof pipe from endangering the electronic unit of the instrument.
4. Instruments installed according to explosion-proof requirements must be equipped with certified sealing stuffing boxes or explosion-proof steel pipe sealing joints for each wiring connected to the explosion-proof enclosure.
5. Please consult our company and agents for certified sealing stuffing boxes or explosion-proof pipe sealing joint products. The instrument installation area requires lightning protection devices to prevent lightning strikes.
6. The ripple of 24VDC power supply shall not exceed 200mV.
7. The power grounding wire should be connected to the standard ground or standard ground instrument ground, and should not be connected to the power ground.

Installation precautions:
1. The installation position should not be too close to the feeding port, otherwise false echoes may be received during feeding.
3. For cylindrical raw coal bunkers, they should be installed at half the radius of the cylinder, and the sensor should be aligned with the discharge port.
3. Wiring
The required voltage level for level switches varies depending on the model. In order to ensure personal safety and the integrity of the instrument, wiring should be done in the event of a power outage.
The wiring methods are divided into two wire system and four wire system,
As we are collecting a 4-20mA current signal, to prevent electromagnetic interference on site and ensure signal accuracy, shielded cables should be used with one end grounded.
