Installation of relative data logger (VG versions)
Ambient pressure is compensated physically on VG versions. The ambient pres
-
sure is fed to the back of the pressure sensor on the level sensor, via a capillary
tube integrated into the sensor cable.
If pressure compensation via the capillary tube is impeded or prevented by con-
tamination or moisture inside the capillary tube, the result of the level measure-
ment will be affected.
Standard version
The pressure compensation aperture is located be-
hind the removable protective tube, which is perforated.
This opening for the cable capillary is protected against water
penetration by a Goretex
®
diaphragm.
A thread to insert moisture absorber cartridges is provided on
the plug component of VG versions (minimum inner diameter
of tube: Ø 35 mm). It is advisable to use moisture absorber
cartridges for measuring points with harsh ambient conditions.
