A condition sensing bulb portion interconnected to capillary tube means that provides fluid communication therethrough to the chamber of the bulb portion whereby the tube and the bulb portion define a juncture area therebetween. Insulating means is carried by the device for insulating the juncture area at the exterior thereof so that substantially no adverse wide temperature gradient can be created between the bulb portion and the juncture area when the bulb portion is subjected to relatively high temperatures provided by flames imposed on the bulb portion. Such insulating means can be a metal sleeve disposed about the juncture area to provide a dead airspace about the juncture area.
