The invention discloses a high and low temperature early warning bimetal thermometer comprising a meter case, a protection tube, a dial, a pointer, a pointer shaft, a temperature-sensitive member, an alarm, a first proximity switch and a second proximity switch. The meter case is connected to the protection tube. An accommodating chamber is arranged in the meter case. The accommodating chamber comprises a first accommodating chamber and a second accommodating chamber. A side edge of the meter case is provided with an early warning box. The alarm is installed in the early warning box. The pointer is positioned in the first accommodating chamber, and is installed at one end of the pointer shaft. The other end of the pointer shaft is connected to the temperature-sensitive member. The dial is positioned in the first accommodating chamber and positioned below the pointer. The dial is provided with a high temperature early warning line and a low temperature early warning line. The first proximity switch and the second proximity switch are both installed in the second accommodating chamber. The first proximity switch is in electric connection with a wiring terminal of a high temperature alarm line. The second proximity switch is in electric connection with a wiring terminal of a low temperature alarm line. According to the invention, a high and low temperature early warning function of the bimetal thermometer is realized, and investment of enterprise production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of instruments and appliances, in particular to a high and low temperature early warning bimetallic thermometer. Background technique [0002] The bimetallic thermometer is an on-site detection instrument for measuring medium and low temperatures. It can directly measure the temperature of liquid vapor and gas medium in the range of -80°C-+500°C in various production processes. The main component of an industrial bimetallic thermometer is a multi-layer metal sheet composed of two or more metal sheets laminated together, which works on the principle that two different metals expand differently when the temperature changes. During the working process, when one end is heated and expanded, it drives the pointer to rotate, and the working instrument will display the temperature value corresponding to the thermoelectric potential. [0003] With the development of science and technology and the needs of modern ind...
