The Wika Resistance thermometers of this series 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 can be removed without taking out the complete sensor from the plant. This enables inspection, measuring equipment monitoring or, when servicing is necessary, replacement while the plant is running.

Application ranges from -50 to +250 °C
With integrated fabricated protection tube
Sensor built in the tip of the protection tube
