Introduction

1.1

Applications

The device is used for level monitoring in all types of containers and silos.
It can be used with all powdery and granulated bulk materials with a density greater than
20 g/l (1.25 lb/ft
The units can be delivered with Ex-approvals for use in Dust Hazardous Areas.
A selection of fields of application:
●
Building materials industry
–
● Food industry
– milk powder, flour, salt, etc.
● Plastics industry
– plastics granules etc.
● Timber industry
● Chemical industry
● Mechanical engineering
The LVS300 oscillating probe is normally screwed into the lateral container wall so that it is
level with the filling height to be registered and monitored.
The device can also be mounted from the top of the container. In this case an extension
piece is used to mount the probe level with the height to be registered.
The length of the probe can be up to 4 m (157") with an extension.
The use of a sliding sleeve is recommended so that the switch point can be changed
continuously during operation of the device.
1.2

Function

The piezo-electrically stimulated oscillating rod vibrates at its mechanical resonance
frequency. If the probe is covered by the bulk material, the damping thus generated is
registered electronically and a corresponding signal output is actuated.
The oscillation of the rod ensures a certain self-cleaning effect.
