The measuring inserts for thermocouples described here are designed for installation in a thermometer model TC10-L. Operation without thermowell is appropriate only in special cases. The measuring insert is made of flexible, mineral insulated sheathed cable. The sensor is located in the tip of the measuring insert. This model is spring-loaded to ensure that the measuring insert is firmly pressed down on the thermowell bottom. The following versions are possible:

• With mounted sleeve to suit inner diameter of the thermowell
• Without terminal block
• With transmitter

Type and number of sensors, accuracy and connection method can each be selected to suit the respective application.

Only correct measuring insert length and correct measuring insert diameter ensure sufficient heat transfer from thermowell to the measuring insert. The range of applications is completed by designs without terminal block for direct transmitter installation. Optionally, analogue or digital transmitters from the WIKA range can be installed.
