The temperature atwhich the contacts “make” or “break” can be regulated bya temperature adjusting sleeve.This adaptation of the differential-expansion principle givesseveral important control advantages:• Fast ResponseSince the outer shell of the THERMOSWITCH® is theactive sensing member, and not merely a housing, responseto temperature change is almost instantaneous.• Close ControlThe controller’s shell and strut arrangement has “anticipation”characteristics which substantially reduce the amount ofovershoot and undershoot during conditions of rapidtemperature change. Anticipation is produced by an inherent timelag between the shell and struts, which causes the shell‘to “lead” the struts by an interval that varies with the rateof temperature change. With rapid temperature rise, the shellexerts a larger net force on the struts and tends to pull themapart sooner than if the temperature were rising slowly.The result is several degrees or more of anticipation whichhelps produce closer control.• Extreme SensitivityThe strut and contact assembly operates by slow make andbreak. This means that every temperature change, no matterhow small, causes a corresponding change in the spacebetween the electrical contacts. Therefore, contact actioncan be produced by a very small temperature change,which accounts for the THERMOSWITCH® controller’sexcellent resolution sensitivity of 0.1ºF (0.05ºC).• Vibration ResistanceSince the strut assembly is assembled under tension orcompression, a properly installed unit has excellent vibrationresistance and will provide the best possible control underdifficult physical conditions.• Agency ApprovedVarious models are listed or component recognizedby Underwriters Laboratories (UL) and certified by theCanadian Standards Association (CSA).www.fenwalcontrols.com 1-800-FENWAL-1 THERMOSWITCH®, Probe Type Temperature Controller Page 1

When the removal of a hex or couplinghead THERMOSWITCH® controller would require draining ofthe container in which it is inserted, the use of a well assemblypermits removal of the controller at any time without otherdisturbances.When surrounding ambients are subject to extreme changes thusaffecting THERMOSWITCH® control, the well makes itpossible to insert the THERMOSWITCH® controller completelyinto the medium being controlled thereby eliminating theseambient temperature effects or “head effect”.A well offers protection in applications where fluids have acorrosive effect on the brass shell of the THERMOSWITCH®controller.NOTE: Certain gases or liquids (including water at elevatedtemperatures) could be corrosive and/or cause electrolyticaction, which could severely shorten the life of the controller.Where corrosion or electrolysis is suspect, the use ofstainless steel heliarc welded thermowells or variousplatings or coatings may increase controller life. The rateof corrosion or electrolysis is influenced by a great manysystem parameters such as chemical makeup andtemperature of the solution, stray electric currents, etc.Consult the supplier of your chemicals or Fenwal forsuggestions.In addition, use a well to protect the THERMOSWITCH®controller from external forces or blows which could affectits operation.Page 6THERMOSWITCH®, Probe Type Temperature Controller1-800-FENWAL-1www.fenwalcontrols.com
