Rotating Paddle Point Level Switch (LSR)

Operating Principle :

• Trumen rotating paddle level switches are spring loaded eccentricaly driven rotating vanes or blades, which rotate at a slow roational speed of 3rpm maximum, using a geared motor.
• When material is absent, rotating vanes are free to move and motor is held to its normal position by a spring.
• When material level reaches the rotating vanes, it tries to stop the rotation. This causes motor move in reverse as the spring can no longer hold it in its normal position.
• When motor rotates to a suffient degree, a limit switch gets triggered. This stops the power supply to the motor and another limit switch provides potential free output.

Features :

• Rugged construction and design along with proper
• sealing to prevent dust penetration.
• No calibration required.
• Extensible length model available
• Different types of blades (vanes) available.
• Stable and reliable performace

Applications : LSR is suitable for applications in free-flowing solid powders and grainules, for example in cement industries, plastics, pharmaceuticals, chemicals and fertilizers, powder, food and breweries, etc.
