SITRANS LPS200 Introduction
The SITRANS LPS200 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/ft3) with the
standard measuring vane, 35 g/l (2.2 lb/ft3) with the optional hinged vane, or 15 g/l
(0.9 lb/ft3) with the optional rectangular vane.
SITRANS LPS200 Features
• High integrity mechanical seal
• AC, DC, or switch-selectable 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/ft3)
• 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
SITRANS LPS200 Applications
• Grain, feed, cement, plastic granulate, wood chips, rice, soybeans, etc.
• Low or high bulk density materials
Principle of Operation
A low revolution gearing motor drives a rotating measuring vane. When material reaches
the rotating vane, rotation stops, actuating a microswitch contact closure. When the
vane is no longer covered, rotation resumes and the microswitch reverts to its normal
condition.
The synchronous induction motor is freely suspended within the housing. When the
rotation is slowed by the material, the reaction torque is used to operate a micro-switch
that gives an electrical signal to stop the motor. When the material level moves away
from the rotating vane, a spring draws the motor back into operating position, the
microswitch returns to operating position, and the motor is switched back on.
Two motor speeds are available: 1 rpm, for storage silos
5 rpm, for faster process requirements
Notes
• Installation, maintenance, and commissioning must be performed by qualified
technical personnel.
• SITRANS LPS200 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.

Installation
Mounting
SITRANS LPS200 is normally mounted into the vessel top (full detector) or through the
tank wall at the detection level (full, demand or empty detector). SITRANS LPS200 can be
installed through a standard 1¼" NPT or 1½" BSPT pipe coupling, depending on the
chosen process thread.
Notes:
• 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.
WARNINGS:
• This product is designated as a Pressure Accessory per
Directive 97/23/EC, and is not intended for use as a safety device.
• Improper installation may result in loss of process pressure.

After mounting and as a precaution
against water ingress into the
housing, turn the housing clockwise
until the cable entries point
downward.
Notes:
• 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.

SITRANS LPS200, Einleitung
Der Drehflügelmelder Pointek LPS200 überwacht den Füllstand von Schüttgütern. Das
Drehflügelprinzip eignet sich für die Voll-, Bedarfs- oder Leermeldung bei Materialien wie
Getreide, Futterstoffe, Zement, Kunststoffgranulat und Holzspäne in Silos, Trichtern oder
Lagerbehältern. Mit dem Standardmessflügel misst der Drehflügelmelder bei niedrigen
Schüttdichten von 100 g/l (6.2 lb/ft3), mit dem optionalen Klappflügel bis 35 g/l (2.2 lb/ft3)
und mit dem optionalen Rechteckflügel sogar bis 15 g/l (0.9 lb/ft3).
SITRANS LPS200, Funktionen
• Mechanische Dichtung
• AC-, DC- oder per Schalter wählbare Spannungsversorgung
• Einzigartige Rutschkupplung. Stößt der Messflügel auf plötzlichen Widerstand, so
verhindert die Rutschkupplung eine Beschädigung interner Bauteile.
• Optionale Laufüberwachung für Alarm bei Fehlerbedingungen oder Ausfall eines
Bauteils
• Verdrehbares Gehäuse
• Optionale Messflügel für den Einsatz bei hoher oder niedriger Schüttdichte bis 15 g/l
• Kurze Ausführung, Ausführung mit Verlängerungsrohr senkrecht (nur Einbau von
oben), Winkelausführung und Seilverlängerungen verfügbar
• Ausführungen für hohe Temperaturen und für hohen Druck verfügbar
• Optionales Verlängerungsset für die kompakte Ausführung verfügbar
SITRANS LPS200, Anwendungsbereiche
• Getreide, Futter, Zement, Plastikgranulat, Holzspäne, Reis, Sojabohnen, usw.
• Materialien mit hoher oder geringer Dichte
Funktionsprinzip
Ein drehgelagerter Messflügel wird von einem Synchrongetriebemotor angetrieben.
Erreicht das Füllgut den Messflügel, so wird dieser angehalten. Es kommt zu einem Kon-
taktschluss des Relais. Wenn der Messflügel nicht mehr bedeckt ist, dreht er sich erneut
und das Relais kehrt in seinen normalen Zustand zurück.
Der synchronisierte Induktionsmotor ist frei im Gehäuse aufgehängt. Wenn die Drehbe-
wegung durch das Material gebremst wird, entsteht ein Reaktionsdrehmoment, das ein
elektrisches Signal zum Stoppen des Motors ausgibt. Sobald sich der Materialfüllstand
vom Drehflügel entfernt, bringt eine Feder den Motor in seine Betriebsstellung zurück.
Zwei Motorgeschwindigkeiten sind verfügbar: 1 U/min, für Lagertanks
5 U/min, für höhere Geschwindigkeits-
anforderungen des Prozesses
Hinweise:
• Installation, Wartung und Inbetriebnahme müssen durch qualifiziertes, technisches
Personal vorgenommen werden.
• Der SITRANS LPS200 darf nur gemäß den Anweisungen in dieser Betriebsanlei-
tung verwendet werden.
• Dieses Produkt ist für den Einsatz im Industriebereich vorgesehen. Bei Verwendung
in Wohngebieten kann es zu Störungen von verschiedenen Funkanwendungen
kommen.
