2. Design and function / 3. Safety
Ungrounded measuring point
The model TRxx or model TCxx thermometers consist of a welded tube, a mineral-
insulated sheathed cable or ceramic-insulated thermocouple wires in which the
temperature sensor is located. This is embedded in a ceramic powder, a temperature-
resistant sealing compound, cement compound or a heat transfer paste.
Thermocouples, non-insulated (grounded)
For special applications, for example surface temperature measurements, the sensors are
in direct contact with the protective sleeve, or the measuring points of thermocouples are
welded to the bottom.
Insulated measuring point (ungrounded)
Thermocouple
Electrical connection
In terms of connection, the thermometer has a case and a plug or bare wire ends. The case
design will contain the connection terminals or certified transmitters. Optionally, separately
certified digital displays can be built into the cases.
