Description

The measuring inserts for resistance thermometers described here are designed to be installed in a protective assembly. Operation without thermowell is only recommended in certain applications. These measuring inserts are made from a flexible, mineral-insulated sheathed cable. The sensor is mounted in a rigid tube at the end of the measuring insert. In addition to being flexible, this model has exceptional resistance to vibrations.

The screw nut placed on the ceramic block allows a comfortable connection with the connecting cable.

This model is spring loaded to ensure that the measuring insert is firmly seated on the bottom of the thermowell, which provides:

• fast response time,
• length compensation (+/- 10 mm),
• reduced vibrations inside the thermowell
