The temperature stability of the sudden jump thermostatAccording to the author's practical experience, the guarantee requirements for the temperature stability of the sudden jump temperature controller are briefly introduced. The sudden jump thermostat has the advantages of high precision, small size, long life and good vibration resistance. As the main component of temperature control, overheat protection, temperature display and over temperature alarm, the sudden jump thermostat has temperature stability as one of the most important technical indicators. Kick-type thermostats are generally closed, consisting of thermal bimetallic elements, linkage mechanisms, contact assemblies, housings and other main components. The main difference between it and the slow-acting or quick-acting thermostat is that the hot bimetal is pre-processed into a disc-shaped disc. During the temperature change cycle, the disc does not continuously change its curvature, but is flat and flat. The two stable positions of the straight state are symmetrical for a sudden jump. The two contacts are quickly opened or closed through the linkage mechanism. It is very important to ensure that the thermal bimetallic sheet has a sudden jump at the rated temperature value and to ensure its temperature stability from the internal quality. In the processing and manufacturing process, the thermal bimetallic disc of the sudden jump thermostat is generally processed into an arch according to the deflection that may be formed by the temperature rise. Relatively speaking, the larger the domed wafers have higher jump values for temperature.
