4 Mounting

4.1 General instructions

Make sure that all parts of the instrument coming in direct contact

with the process, especially the sensor element, process seal and

process fitting, are suitable for the existing process conditions, such

as process pressure, process temperature as well as the chemical

properties of the medium.
You can find the specifications in chapter "Technical data" and on the

nameplate.

Select such a mounting location that the instrument is within easy

reach for mounting and connecting. For this purpose the housing can

be rotated by 330° without any tools being required.

Before beginning the welding work, remove the electronics module

from the sensor. By doing this, you avoid damage to the electronics

through inductive coupling.

With threaded versions, the housing must not be used to screw in the

instrument. Applying tightening forces on the housing can damage its

internal parts.
Use the hexagon for screwing in.

Use the recommended cables (see chapter "Connecting to power

supply") and tighten the cable gland.
You can give your instrument additional protection against moisture

penetration by leading the connection cable downward in front of the

cable entry. Rain and condensation water can thus drain off. This ap-

plies mainly to outdoor mounting as well as installation in areas where

high humidity is expected (e.g. through cleaning processes) or on

cooled or heated vessels.

Fig. 4: Measures against moisture penetration

The process fitting must be sealed if there is gauge or low pressure in

the vessel. Before use, check if the seal material is resistant against

the measured product and the process temperature.
The max. permissible pressure is specified in chapter "Technical

data" or on the type label of the sensor.
