Sitrans LPS200 is a rotary paddle switch for point level detection in bulk solids. The paddle switch technology detects full, empty or demand conditions on cement. 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. A low revolution geared motor with slip clutch drives a rotating measuring vane, which senses the presence of the 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. 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 weight materials.
