Resistance rotary level switch

PRL series Resistance rotary level switch

1. Working principle

Comply with the Restriction on Hazardous Substances (ROHS) directive）The requirements. No need to adjust sensitivity, it can be used when powered on. Even if there is a slight change in the measured object, there will be no misoperation. Capable of handling level detection of powders and materials with a wide range and flexible maneuverability.
PaddleLeaf type level switch is a contact type level switch that performs detection based on the density of the measured object. Therefore, in the same container, even if there is a change in the tested object, there is little need to worry about misoperation. Moreover, when used for ultra low density tested objects, only the detection needs to be replacedpaddleLeaves, without the need for cumbersome sensitivity adjustments.
Therefore, as a simple mechanical device, compared with level switches based on other principles, it has strong resistance to vibration and impact, and the material is testedpaddleHanging materials on the blades and spindle is not a problem, and it can be said to be the most commonly used level switch for powder level detection.

3. Installation and precautions

Precautions during assembly:

✔ When directly assembled in silos, barrels, etc

The standard assembly method is to set up on the side walls of the silo, barrel, etcAn opening with a diameter of over 82mm allows the blade to pass through. When assembling propeller blades from the inside of silos, barrels, etc., please setΦ40mmThe above opening.

✔ When assembling short tubes for configuration

When assembling propeller blades from the inside of silos, barrels, etc., please set them on the side wallsOpenings larger than 40mm in diameter. Without assembling the propeller blades from the inside, set the flange size to 5K80A or above, and also set the inner diameter of the short pipedoΦ82mmabove,Enable the blades to pass through.

HL-400 series Resistance rotary level switch Compact and economical

1. Working principle

Paddle type level switch is a contact type level switch that performs detection based on the density of the measured object. Even if there is a slight change in the measured object, there will be no misoperation, making it easy to use. When detecting ultra-low density measured objects, only the detection blade needs to be replaced. It is a simple mechanical device that has strong resistance to vibration and impact compared to level switches based on other principles. It can also overcome the problem of hanging materials and is the most suitable level switch for powder level detection. The HL-400 series is an economical resistive rotary level switch.

2 HL-Product features of 400

- Ultra small paddle type level switch!

- Most suitable for level detection in small silos and containers.

A complete lineup that can meet various purposes.
