Abstract
A pressure-biased, temperature sensor for monitoring a fluid system for either an over-temperature or under-pressure condition. These conditions are sensed by one of two expandable bellows operators which cooperates with the other bellows operator and a lever and fulcrum arrangement to close a switch, completing a signal circuit and energizing a signal means.
