3.2 Principle of operation

The instrument is suitable for applications in liquids and bulk solids in

vesselsunderdicultprocessconditions.Thereareapplicationpos-

sibilities in nearly all areas of industry.

The limit level is detected contactlessly through the vessel wall. Nei-

theraprocessttingnoravesselopeningisrequired.Theinstrument

isthusidealforretrotting.

In radiation-based measurement, a Caesium-137 or Cobalt-60 iso-

tope emits focussed gamma rays that are attenuated when penetrat-

ingthevesselwallandthemedium.ThePVTdetectorontheopposite

side of the tank receives the radiation. When the intensity of the

radiationdropsbelowadenedvalue,e.g.duetodamping,thenthe

POINTRAC 31 switches. The measuring principle has proven itself

well under extreme conditions because it measures contactlessly

from outside through the vessel wall. The measuring system ensures

maximum safety, reliability and plant availability independent of the

medium and its properties.

3.3 Packaging, transport and storage

Your instrument was protected by packaging during transport. Its

capacity to handle normal loads during transport is assured by a test

based on ISO 4180.

The packaging of standard instruments consists of environment-

friendly, recyclable cardboard. For special versions, PE foam or PE

foil is also used. Dispose of the packaging material via specialised

recycling companies.

Transport must be carried out in due consideration of the notes on the

transport packaging. Nonobservance of these instructions can cause

damage to the device.
