The WIKA TW22 thermowell is used to adapt thermometers and measuring inserts to the process and protects the sensor against harsh process conditions. The thermowell is mounted to a weld-in nozzle equipped with a respective hygienic connection and is built-in pipelines and tanks. Through the rotatable threaded connection, the connection head or display can be loosened and adjusted to the desired position. With a combination of a WIKA TR21-A or WIKA TR22-A resistance thermometer, the connection head is removable along with the measuring insert. This enables the thermometer to be calibrated along with the complete measuring chain, i.e. without disconnecting the electrical connections. In addition, this avoids having to open the process, and thus the risk of contamination is minimised.

Each thermowell is an essential component of any temperature measurement point. The WIKA TW45 thermowell is used to separate the process from the surrounding area, thus protecting the environment and operating personnel and keeps aggressive media, high pressures and flow rates from the temperature sensor itself and thereby enables the thermometer to be exchanged during operation. Based on the almost limitless application possibilities, there are a large number of variants, such as thermowell designs or materials. The type of process connection and the primary method of manufacture are critical design differentiation criteria. A necessary differentiation can be made between threaded and weld-in thermowells, and those with flange connections. Furthermore, one can differentiate between fabricated and solid-machined thermowells. Fabricated thermowells are constructed from a tube, that is closed at the tip by a welded solid tip. Solid-machined thermowells are manufactured from bar stock. The TW45 series of fabricated 1) screw-in thermowells are suitable for use with numerous electrical and mechanical thermometers from WIKA. Due to their design to DIN 43772, these thermowells for low and medium process loads are suitable for use in the chemical industry, process technology and equipment manufacture. 1) For short insertion lengths (copper alloy) solid-machined version optionally
