2. Design and function

2.1 Description

The model TR12-B (resistance thermometer) and model TC12-B (thermocouple) electrical thermometers consist of a module (TR12-M, TC12-M) which is built into a case. The module is made up of a spring-loaded measuring insert (TR12-A, TC12-A) built into a neck tube. The measuring insert (TR12-A, TC12-A) is replaceable.

The active measuring component of the measuring insert is manufactured from a welded tube or from mineral-insulated cable, optionally in combination with ceramic-insulated thermocouple wires. The sensor is embedded in ceramic powder, heat-resistant potting compound, cement compound or thermally conductive paste.

1. General information / 2. Design and function

14064370.02 08/2018 EN/DE/FR/ES

WIKA operating instructions models TR12, TC12

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.
