2. Design and function
If the temperature sensor is designed as a grounded thermocouple, the thermocouple
is joined directly to the sheath. Versions with a diameter smaller than 3 mm and with
grounded thermocouples should be considered as galvanically connected with earth
potential.
The connection side of the measuring insert consists of a transition sleeve with connected
bare wires.
This document describes standard versions of instruments. For applications in hazardous
areas special instrument designs are required.
For further information for operation in hazardous areas, see the additional information for
the corresponding ignition protection type (separate document).
CAUTION!
Damage to the instrument
To avoid damage to the instrument, thermometers of this model range must
be installed with a thermowell.
▶
Select a suitable thermowell (any type of thermowell can be selected) and
take the operational process data (temperature, pressure, density and
flow velocity) into account.
▶
The use of special designs without thermowell is possible, but is the
responsibility of the operator.
Possible sensor measuring ranges:
Model TR12: -200 ... +600 °C
Model TC12: -40 ... +1,200 °C
The following mounting and operating information has been compiled with care. However, it
is not possible to consider all potential usage cases.
