SIEMENS SITRANS LPS200 Rotary Paddle Level Switch

The SITRANS LPS200 serves as a rotary paddle switch specifically designed for point level detection in bulk solids. This technology is adept at detecting full, empty, or demand conditions in materials such as grain, feed, cement, plastic granulate, and wood chips. Notably, it can handle bulk densities as low as 15 g/l (2.19 lb/ft³) with the optional hinged vane or 100 g/l (6.25 lb/ft³) with the standard measuring vane.

The switch operates through a low revolution geared motor with slip clutch, driving a rotating measuring vane. As material makes contact with the rotating paddle, rotation halts, triggering a change in the microswitch state. Once the material no longer covers the paddle, rotation recommences, and the relay returns to its normal condition. The LPS200 boasts a rugged design tailored for harsh conditions in the solids industry. Its paddle sensitivity can be adjusted to accommodate varying material properties, such as buildup on the vane.

Offered in compact, extended, and cable extension configurations, the LPS200 is equipped with a standard vane effective in most applications. Additionally, it can be configured with a hinged or rectangular vane to enhance sensitivity for light materials.

Application

The paddle switch technology detects full, empty, or demand conditions on materials such as grain, feed, cement, plastic granulate, and wood chips. The paddle switch can handle bulk densities as low as 15.06 g/l (0.94 lb/ft3) with the optional rectangular vane or 100 g/l (6.25 lb/ft3) with the standard measuring vane.

A low revolution geared motor with slip clutch drives a rotating measuring vane which senses the presence of material at the mounted level of the LPS200. As material comes into contact with the rotating paddle, rotation stops, which changes the microswitch state. When the paddle is no longer covered by material, rotation resumes and the relay reverts to its normal condition.

The LPS200 has a rugged design for use in harsh conditions in the solids industry. The sensitivity of the paddle can be adjusted for varying material properties like buildup on the vane.

The LPS200 comes in a variety of configurations including compact, extended and cable extension. It is equipped with a standard vane which is effective in most applications, but can be configured with a hinged or rectangular vane for increased sensitivity for light materials.
