4.2 Description
These resistance thermometers and thermocouples are used for temperature measure-
ment in industrial applications.
This document describes standard versions of instruments. For applications in hazard-
ous 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).
Transmitters or digital indicators built into the thermometer have their own operating
instructions.
Model TRxx resistance thermometers consist of a sensor section made of mineral-in-
sulated sheathed cable or welded tube. In both versions, the temperature-sensitive
measuring resistor is built into the probe tip.
