Each thermowell is an essential component of any temperature measurement point. The WIKA TW25 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 barstock. The WIKA TW25 series of solid-machined thermowells with flange connection are suitable for use with numerous electrical and mechanical thermometers from WIKA. Due to the heavy-duty design, these international design thermowells are the first choice for use the chemical and petrochemical industries and in plant construction. This thermowell can also be ordered with the innovative ScrutonWell® design. The added helical shape on the outside of the insert increases the thermowell™s resistance to the Kármán vortex street and the stress this causes on the instrument by breaking the vortex up into smaller vortices. By incorporating the helix onto the outside of the thermowell, the Scrutonwell® design reduces oscillation by more than 90%!

The WIKA 332.30 / 333.30 high-quality test gauge has been specifically designed for increased safety requirements during high-accuracy pressure measurements and is suited for calibration tasks. With an accuracy class of 0.6 %, the Bourdon tube pressure gauge is suitable for testing industrial type pressure gauges or for precision measurement in laboratories. Optionally, an accuracy class of 0.25 % is possible for pressures up to 400 bar. The wear-resistant precision movement, the wetted parts and the case are made from high-grade stainless steel. WIKA manufactures and qualifies the Bourdon tube pressure gauge in accordance with the requirements of the EN 837-1 European standard in the S3 safety version. The safety version is made up of a non-splintering window, a solid baffle wall between measuring system and dial and a blow-out back. In the event of a failure, the operator is protected at the front side, as media or components can only be ejected via the back of the case. For harsh operating conditions (e.g. vibrations), all instruments are also available with an optional liquid filling. The optimal readability of the instrument, with a nominal size of 160 mm, is achieved via a knife-edge pointer and a dial with fine divisions. Supported through the optional mirror band scale, the parallax error can be eliminated.
