Abstract
A replaceable sensing and indicating element for a bi-metallic thermometer of the type having an enclosure and a stem. The sensing and indicating element comprises a stem terminating in a bi-metal helical temperature sensing coil, a shaft extending inside the stem from the coil, an indicating pointer secured to the shaft, a calibrated temperature scale, adjustment means for orienting the scale, and a connector affixed to the sensing element stem. The sensing element is telescopically received within the thermometer enclosure and stem and is held in place by a bezel ring and restraining means. Accordingly, the sensing element may be easily removed from and replaced in the enclosure.
