Abstract
A pressure-biased, temperature sensor means utilizing a cooperating pair of aligned bellows operators in a chamber communicating with a fluid to a reference pressure. One of the bellows is responsive to an elevated temperature of a fluid coolant system and the second bellows, which communicates with the fluid coolant system, is responsive to a decrease in fluid pressure. The aligned bellows cooperate to move a switch actuation means to close a switch thereby completing a signal circuit and energizing a signal means.
