Abstract
Abstract A temperature indicator for use in combination with a plumbing fitting through which water passes has a core assembly including a display, a circuit module fixed to and driving the display, a temperature sensor connected to the circuit module, a pair of long battery contacts connected to the module, a finger extending from the module and carrying the long contacts, and a pair of short battery contacts connected to the module in parallel with the long contacts. An inner housing part interfitting with the fitting and traversed by the water is formed with a recess in which the sensor is engageable. A battery is connected to one of the pairs of contacts and the other pair is unused. An outer housing part mounted on the inner housing part carries the core assembly. The finger is constructed to break readily off the assembly.
