Functional principle
2.2 Principle of
The protective cover is an accessory or retrofit part for level, switching
and pressure sensors from the VEGA plics® product line. It is suitable
for sensors with or without indicating and adjustment module. The
height difference of the housing is compensated by the supplied foam
rubber adapter disc.
With double chamber housings, the indicating and adjustment module
must be mounted on top.
The protective cover protects the sensor housing against soiling and
intense heat from solar radiation when it is mounted outdoors.
It consists of two half-shells with hinge held together by a snap-on
connection. A secure hold on the sensor housing is ensured via
fastening elements. Ventilation slots allow air circulation.
The protective cover is put on after the sensor is mounted and
commissioned. It is not necessary to interrupt the electrical connection.
