Mounting

4.1

General instructions

Suitability for the process conditions
Make sure before mounting that all parts of the
instrument exposed to the process are suitable
for the existing process conditions.
These are mainly:
•
Active measuring component
•
Process fitting
•
Process seal
Process conditions in particular are:
•
Process pressure
•
Process temperature
•
Chemical properties of the medium
•
Abrasion and mechanical influences
You can find detailed information on the process
conditions in chapter "Technical data" as well as
on the type label.
Suitability for the ambient conditions
The instrument is suitable for standard and
extended ambient conditions acc. to DIN/EN/
IEC/ANSI/ISA/UL/CSA 61010-1.

Mounting versions

Straining clamp
Most simply mount the instrument via the
straining clamp. For this purpose, the connec-
tion cable is provided with a strain relief wire of
Kevlar.
In order to avoid faulty measured values, make
sure that the sensor does not oscillate.

Mounting bracket
For a rigid mounting, a mounting bracket with
opening for thread G1½, e.g. from the VEGA
product range, is recommended. The mounting
of the sensor in the bracket is carried out via a
G1½ counter nut of plastic. Take note of chapter
"Mounting instructions" for the distance to the
wall.

Mounting instructions

Polarisation
The emitted radar impulses of the radar sensor
are electromagnetic waves. The polarisation is
the direction of the electrical wave component.
By turning the instrument in the mounting strap,
the polarisation can be used to reduce the
effects of false echoes.
The position of the polarisation is in the middle
of the type label on the instrument.

Inflowing medium
Do not mount the instrument in or above the
filling stream. Make sure that you detect the
product surface, not the inflowing product.
