• When mounting rod and cable versions, make sure that the probe head is located at a point
as free as possible from flow. To protect the probe from impact resulting from lateral
movement, mount the probe in a guide tube (preferably made of plastic) or secure it with
a clamping fixture.
• In the case of devices for hazardous areas, comply strictly with the safety instructions
when the housing cover is open.
• The length of the extension cable or the probe rod is based on the planned level zero point.
The height of the protective cap must be taken into consideration when designing the
layout of the measuring point. The level zero point (E) corresponds to the position of the
process isolating diaphragm.
Level zero point = E; top of the probe = L.
