The WIKA TR12-B and TR12-M resistance thermometers in this series can be combined with a large number of thermowell designs. The replaceable, centrally spring-loaded measuring insert and its extended spring travel enable combination with the widest range of connection head designs. A wide variety of possible combinations of a sensor, connection head, insertion length, neck length, connection to thermowell, etc. are available for the thermometers; suitable for any thermowell dimension and any application. Please take note that operation without thermowell is appropriate only in special cases.

WIKA TR11-C resistance thermometers are designed for screw-fitting directly into the process, mainly in vessels and pipelines. These thermometers are suitable for liquid and gaseous media under moderate mechanical load and normal chemical conditions. The protection tube made of stainless steel is all welded and screwed into the connection head. An optional measuring insert (tubular design) can be removed without taking out the complete sensor from the plant. This enables inspection, measuring equipment monitoring or, when servicing is necessary, a replacement while the plant is running. Insertion length, process connection, protection tube design, connection head, type and number of sensors, accuracy and connection method can each be selected to suit the respective application. Optionally we can fit analogue or digital transmitters from the WIKA range into the connection head of the TR11-C.
