Rotary paddle level switch SIEMENS Process Instrumentation

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 materials such as grain, feed, cement, plastic
granulate and wood chips. The paddle switch 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 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.
