Measuring insert
Description
The measuring inserts described here are intended for installation in model TR12-B or TR12-M process resistance thermometers (see figures at right). Operation without thermowell is only recommended in certain applications.
The measuring insert is made of flexible, mineral-insulated sheathed cable. The sensor is located in the tip of the measuring insert.
Type and number of sensors, accuracy and connection method can each be selected to suit the respective application.
