TBI-S Bi-Metallic Thermometer

Brand: KOBOLD Instruments, Inc.

The bimetallic thermometers are used on site for direct temperature measurement. A wide range of standard versions allows a variety of applications. Furthermore special versions are manufactured to customer specification. Special areas of application heavy industrial plants, piping and vessels, machines etc.

The devices are installed into a thermowell with adjusting screw. Simply screw in the thermowell, plug in the thermometer and clamp with the adjusting screw. The measuring element of the bimetallic thermometer is a fast-response bimetallic helix.

It is manufactured from two cold-welded strips of metal with different thermal coefficients of expansion and it becomes twisted as a function of temperature. The rotary motion is transferred with low friction to the pointer.
