A false signal suppression with installed sensor is generally rec-
ommended to achieve the best possible accuracy.
Instruments for a temperature range up to +280 °C (536 °F) or up to
+450 °C (842 °F) have a distance piece between process tting and
electronics housing. Ths distance piece is used for thermal decou-
pling of the electronics against high process temperatures.
Information:
The spacer may be incorporated in the vessel insulation up to max.
50 mm (2 in). Only then is a reliable temperature decoupling guaran-
teed.

If there is a risk of the cable probe touching the vessel wall during
operation due to product movements or agitators, etc., the measuring
probe should be securely xed.
In the gravity weight there is an internal thread (M8), e.g. for an eye-
bolt (optional) - (article no. 2.1512).
Make sure that the probe cable is not completely taut. Avoid tensile
loads on the cable.
Avoid undened vessel connections, i.e. the connection must be
either grounded reliably or isolated reliably. Any undened change of
this condition can lead to measurement errors.
If there is a danger of the rod probe touching the vessel wall, then the
probe must be fastened at the bottom end.
