SITRANS LVS200 Introduction

Notes

• Installation, maintenance, and commissioning must be performed by qualified

English

technical personnel.

• SITRANS LVS200 must be used only in the manner outlined in this instruction
manual.

SITRANS LVS200 is available in three versions:

• The SITRANS LVS200, standard version, is a vibrating level switch that detects high
or low levels of dry bulk solids in bins, silos, or hoppers. SITRANS LVS200 provides a
contact output for levels of products such as lime, styrofoam, flour, and plastic
granules. The compact design allows SITRANS LVS200 to be top or side mounted.
The standard length LVS200 fork is also available with variable cable extension
lengths to a maximum of 20 000 mm (787"). An optional longer fork is available for
increased sensitivity. SITRANS LVS200 cable extension is for top mount applications
only. The vibrating fork design ensures that the tines are kept clean.

• The SITRANS LVS200, liquid/solid interface version, is a vibrating level switch that
can also detect settled solids within liquids, or solids within confined spaces such
as feed pipes. This version is designed to ignore liquids in order to detect the
interface between a solid and a liquid. The design incorporates a short fork, and is
also available with variable cable extension lengths to a maximum of 20 000 mm
(787"), for top mount applications only.

• The SITRANS LVS200, pipe extension version, is a vibrating level switch that
incorporates a customer supplied pipe extension [maximum length 3800 mm (150")]
with the standard or liquid/solid (short) LVS200 fork and electronics. This allows for
separation of the electronics and tuning fork for specialized applications. Please

Principle of Operation

A signal from the electronic circuit excites a crystal in the probe, causing the fork to
vibrate. If the fork is covered by material, the change in vibration is detected by electronic
circuitry which causes the relay to change state after a one second delay. When the
material no longer reaches the tines, full vibration resumes and the relay reverts to its
normal state.

WARNINGS:

• This product is designed as a Pressure Accessory per Directive 97 / 23 / EC
and is not

• Materials of construction are chosen based on their chemical
compatibility (or inertness) for general purposes. For exposure to
specific environments, check with chemical compatibility charts
before installing.

Vibration amplitude diagnosis

NAMUR module (IEC 60947-5-6) and and 8/16 mA or 4 to 20 mA model

Measurement quality is related to the vibration amplitude of the fork. The diagnostic LED
indicates the quality of the vibration being sent to the LVS200 electronics.

English

mmmmm

• Diagnostic LED off: measurement quality is good. The vibration amplitude is strong.

• Diagnostic LED blinking: measurement quality is poor and vibration amplitude is
decreasing as fork becomes encrusted. When this happens, set the sensitivity
switch to decreased sensitivity.

• Diagnostic LED on: vibration has stopped and fork is fully encrusted with material.

Current output setting

8/16 mA

The chart below illustrates the output current when:

•Fork is clean

• Fork is encrusted: weak vibration amplitude is shown

• Fork is fully encrusted and vibration has stopped.

mmmmm

The output current can indicate weak vibration amplitude with the diagnosis setting D
ON. If the diagnosis is set to D OFF, the output will be either 8 mA or 16 mA depending on
high or low level settings.

If the diagnosis is set to D ON, the output will change from 16 to 20 mA and from 8 to 6 mA
if the vibration is weak. This output can be passed to an external 4 to 20 mA output. There

English

is an internal delay of 10 seconds before the change happens, so that the external output
does not indicate a weak vibration when the vibration is stopped and started during
normal measurement operation.

Buildup Detection (8/16 mA or 4 to 20 mA version)

With the 4 to 20 mA setting, you can recognize material buildup on the fork using a PLC or
data logger.

In this mode, the Diagnostic setting has no influence. The LED showing signal output is
off.

20 mA: The fork is clean.

<20 mA and >12/12.5 mA: The vibration amplitude is decreased by the material buildup.

<12/12.5 mA and >7/8 mA: This range indicates a weak vibration. The internal LED
showing diagnosis begins blinking to indicate a weak signal. If you are using a PLC to
evaluate the echo, delay the response time to this indicator for approximately 10 seconds.
A hysteresis of 0.5 mA (between 12 and 12.5 mA) is recommended.

7/8 mA: This point indicates that the fork is mostly encrusted.

6 mA: This point indicates that the fork is fully encrusted.

SITRANS LVS200: Einleitung

Hinweise:

• Installation, Wartung und Inbetriebnahme müssen durch qualifiziertes, technisches
Personal vorgenommen werden.

• Der SITRANS LVS200 darf nur gemäß den Anweisungen in dieser Betriebsanlei­tung verwendet werden.

Drei Ausführungen des SITRANS LVS200 stehen zur Verfügung:

• Der SITRANS LVS200, Standardausführung, ist ein Vibrations-Grenzstandschalter,
der die An- oder Abwesenheit rieselfähiger Schüttgüter in Behältern, Silos oder
Trichtern erfasst. SITRANS LVS200 liefert einen Signalausgang zur Anzeige eines
Min. oder Max. Alarms. Unterschiedliche Produkte können gemessen werden, wie

z. B. Kalk, Styropor, Mehl und Kunststoffgranulat. SITRANS LVS200 hat ein kompak­tes Design und kann senkrecht oder waagrecht eingebaut werden. Die Standard­Schwinggabelsonde des LVS200 ist auch mit verschiedenen Seilverlängerungen bis
maximal 20 000 mm (787") verfügbar. Für erhöhte Empfindlichkeit steht optional eine
längere Schwinggabelsonde zur Verfügung. Die Seilverlängerung des SITRANS
LVS200 ist nur für den Einbau von oben geeignet. Die vibrierende Schwinggabel
bewirkt eine gewisse Selbstreinigung des Gerätes vom Messstoff.

• Die Ausführung Trennschichtmessung Flüssigkeiten/Schüttgüter des SITRANS
LVS200 ist ein Vibrations-Grenzstandschalter, der auch abgesetzte Feststoffe in
Flüssigkeiten oder Feststoffe in beengten Anlagen, wie z. B. Speiserohren, erfassen
kann. Diese Ausführung ist so konzipiert, dass Flüssigkeiten ignoriert werden, um
die Trennschicht zwischen einem Feststoff und einer Flüssigkeit zu erfassen. Die mit
diesem Design verbundene kurze Schwinggabelsonde ist auch mit verschiedenen
Seilverlängerungen bis maximal 20 000 mm (787"), nur für den Einbau von oben ver­fügbar.

• Die Ausführung Rohrverlängerung des SITRANS LVS200 ist ein Vibrations-Grenz­standschalter, bei dem ein kundenseitiges Verlängerungsrohr [max. Länge 3800 mm
(150")] mit der Standard- oder Flüssigkeit/Feststoff-Ausführung (kurz) von LVS200
Schwinggabel und Elektronik verbunden wird. Dadurch kann die Elektronik für Son­derapplikationen von der Schwinggabel abgesetzt werden. Angaben zum Aufbau
finden Sie unter

Anwendungsbereiche

• Trockenkalk, Styropor, Mehl, Kunststoffgranulat

• Trockenes Schüttgut mit hoher oder geringer Dichte

• Trennschichterfassung von Feststoffen in einer Flüssigkeit (Filterbett)

• Flüssigkeit/Feststoff-Ausführung des LVS200 unterscheidet die Zustände Durch­fluss/kein Durchfluss in Rohren

Arbeitsprinzip

Ein Signal vom elektrischen Schaltkreis bewirkt eine piezoelektrische Anregung der
Sonde, die zum Schwingen gebracht wird. Wird die Sonde durch das Füllgut bedeckt, so
wird die dadurch entstehende Dämpfung elektronisch registriert und ein entsprechender
Schaltausgang nach einer Sekunde Ansprechverzögerung betätigt. Sobald die Schwing­sonde frei vom Materialdruck ist, nimmt die Schwingung wieder auf und das Relais kehrt
in seinen normalen Zustand zurück.

WARNUNGEN:

• Dieses Produkt wird als druckhaltendes Ausrüstungsteil im Sinne der
Richtlinie 97 / 23 / EG bezeichnet und ist nicht
heitsvorrichtung bestimmt.
