High-temperature shaft protection tube-type rotary resistance level switch LD-20T

product manual:

The high temperature shaft protection tube-type rotary resistance level switch LD-20T uses a micro motor as the driving device. The transmission shaft is connected to the clutch. When the material is not in contact with the material, the motor operates normally. When the blade contacts the material, the motor stops rotating and detects The device outputs a contact signal and cuts off the power supply at the same time to stop rotation. When the material drops, the resistance experienced by the blade disappears, and the detection device relies on the torsion spring to return to the original state. The torque can be adjusted for different specific gravity materials.

High-temperature shaft protection tube-type rotary resistance level switch LD-20T is specially used for monitoring the solid point material level in the silo, container and chute. This level controller can reduce overflow, material waste and downtime by preventing silo overflow, chute blockage and silo empty load. LD resistance level controller is also suitable for plastic, food, chemical, iron ore, pellets and other solid materials. High-temperature shaft protection tube-type rotary resistance level switch LD-20T can eliminate the most common faults in ordinary rotary resistance controllers. When adding materials, the power-off motor is turned off without entering the parking state. This reduces wear and operating temperatures, which can extend motor life. This controller has fewer moving parts, three sets of drive bearings and sealed, lubricated gear assemblies. This gives the LD series the most reliable control on the market.
