This new thermowell design prevents vibration

For applications in processes with high flowrates, this company is now offering thermowells in the new ScrutonWell design (photo). This variant dampens the excitation that leads to vibrations, which in turn can cause failures. The helical form of the stem is available in two versions: manufactured in a single piece or with helices welded onto it. Installation and removal are just as easy as with a standard thermowell. ScrutonWell thermowells are recommended when a thermowell fails the strength calculation, according to ASME PTC 19.3 TW-2010, and where other optimizations (shorter or stronger stem or support collar) are not desirable. In comparison with the conventional stem form, the new design reduces the excitations caused by vibration by more than 90%. — WIKA Alexander Wiegand SE & Co. KG, Klingenberg, Germany
