Abstract

The device has a compensation tank (3) provided at a measuring head. A hose (4) is filled with a liquid medium i.e. water, and attached at an end of the tank. A pressure sensor (5) is attached at another end of the tank. The pressure sensor is provided at a reference point. The tank is designed in such a manner that atmospheric pressure effect on a liquid column, and liquid withdrawal are prevented. The tank is attached at a high position on a gas-tight plastic foil of a cover (2). The cover and a container (1) are designed as a plastic bag in a single piece.

Description

Die Erfindung bezieht sich auf eine Einrichtung zur Niveaumessung über einem Bezugspunkt.The The invention relates to a device for level measurement over a Reference point.

Die Einrichtung soll keine mechanischen Teile aufweisen, in einer explosionsgefährdeten Zone einsetzbar und eine genaue Höhenerfassbarkeit aufweisen und überdies kostengünstig sein.The Device should have no mechanical parts in a hazardous area Zone usable and have an accurate height detectability and moreover economical be.

Dies wird mit einer im Anspruch 1 gekennzeichneten Einrichtung erreicht.This is achieved with a device characterized in claim 1.

Im Anspruch 2 ist ein im Hinblick auf die obengenannten Ziele besonders vorteilhafter Anwendungsfall angegeben.in the Claim 2 is particular in view of the above-mentioned objects indicated advantageous application.

Vorteilhafte Ausgestaltungen sind den weiteren Ansprüchen zu entnehmen.advantageous Embodiments are given in the further claims.

Anhand eines Ausführungsbeispiels sei die Erfindung näher erleutert.Based an embodiment let the invention be closer erleutert.

Ein Behälter 1 ist mit einer Kunststofffolie 2 als Abdeckung versehen.A container 1 is with a plastic film 2 provided as a cover.

An der bei maximaler Befüllung höchsten Stelle der Abdeckung 2 ist ein Ausgleichsbehälter 3 außen an der Kunststofffolie 2 befestigt, der über einen mit Wassser gefüllten Schlauch 4 mit einem auf der Höhe des Grundes des Behälters 1 befindlichem Druckaufnehmer 5 verbunden ist.At the highest point of the cover at maximum filling 2 is a surge tank 3 outside on the plastic film 2 attached, which has a hose filled with water 4 with one at the level of the bottom of the container 1 located pressure transducer 5 connected is.

Der Ausgleichsbehälter 3 ist dabei derart ausgebildet, daß auf die Flüssigkeits-Säule der Atmosphärendruck voll einwirkt und gleichzeitig ein Wasseraustritt verhindert wird.The expansion tank 3 is designed such that fully acts on the liquid column of the atmospheric pressure and at the same time a water leakage is prevented.

Vorteihaft steht in Steuerabhängigkeit vom Druckaufnehmer 5 eine Auswerteschaltung, die ein dem Füllstand oder Volumen des gasförmigen Mediums proportionales elektrisches Signal erzeugt.Vorteihaft is in tax dependence of the pressure transducer 5 an evaluation circuit which generates an electrical signal proportional to the level or volume of the gaseous medium.
