Installation, maintenance, and commissioning must be performed by qualified technical
personnel.
The device must be used only in the manner outlined in this instruction manual.
This product is intended for use in industrial areas. Operation of this equipment in a
residential area may cause interference to several frequency-based communications.
3.1 SITRANS LPS200 Overview
The device rotating paddle switch is used for level monitoring of bulk materials. It can be
used to detect full, demand, or empty conditions in silos, hoppers, or storage vessels of
materials such as grain, feed, cement, plastic granulate, and wood chips. The paddle switch
measures bulk densities as low as 100 g/l (6.2 lb/ft
35 g/l (2.2 lb/ft

) with the standard measuring vane,
3.2 Features
● High integrity mechanical seal.
● AC, DC, or universal power supply.
● Unique friction clutch mechanism. When the measuring vane encounters sudden
resistance, the friction clutch slips to prevent internal component damage.
● Optional fail-safe function alarms on fault conditions or component failure.
● Rotatable enclosure.
● Optional vanes for use with high and low bulk densities to 15 g/l (0.9 lb/ft
● Compact, rigid extension (top mounted only), angled rigid extension, and cable extension
configurations available.
● High temperature and high pressure models available.
● Optional extension kit available for the compact version.

Installing/mounting
ote
Installation shall be performed by qualified personnel and in accordance with local
governing regulations.
For heavy material, only top mounting of paddle switch is recommended.
Compact SITRANS LPS200 is recommended for side mounting on bins for low or
intermediate levels.
For SITRANS LPS200 Cable extension, the maximum pull force of the rope must not
exceed 4 kN (28 kN with reinforced option).
When installing LPS200 with rigid extension kit, ensure product is top mounted and never
side or angle mounted.
WARNING
This product is designated as a Pressure Accessory per Directive 97/23/EC and is not
ntended for use as a safety device.
i
WARNING
Improper installation may result in loss of process pressure.
The device is normally mounted into the vessel top (full detector) or through the tank wall at
the detection level (full, demand or empty detector). The device can be installed through a
standard 1¼" NPT or 1½" BSPT pipe coupling, depending on the chosen process thread.

5.1 Food grade material
The materials are available for use under normal and predictable applications (according to
directive 1935/2004 Art. 3). Other conditions can influence safety.
After mounting and as a precaution against water ingress into the housing, turn the housing
clockwise until the cable entries point downward.
Ensure measuring vane is out of any region that is susceptible to build-up.
For heavy material loads and protection against falling material, provide angled
protection.
Ensure cable gland faces downward to avoid water intrusion.
