Problems solved by technology

[0003] The current bimetallic thermometers use electric contacts to alarm the temperature range. However, for the use of different industrial equipment, there are high requirements for temperature. When the temperature exceeds the preset value, an alarm is issued. However, when the temperature is greater than the preset value , the maximum temperature cannot be determined after the temperature is lowered, making it impossible to effectively determine the maximum temperature and assist in judgment after the alarm

Abstract

The invention discloses an electric contact bimetal thermometer capable of automatically powering off and alarming, which comprises a stand column, the upper surface of the stand column is fixedly connected with the lower surface of a base body, the surface of the base body is fixedly connected with the inner wall of a lower shell through a screw, and the surface of the lower shell is fixedly connected with an upper shell through a screw. Through the arrangement of a heat conduction head, an interface, a stand column, a capillary groove, an elastic interface, a backflow groove, a pressure relief groove, a first magnetic block and a second magnetic block, after a calibration needle gives an alarm, scale self-locking can be achieved when the thermometer reaches a preset value marked by an adjusting screw, whether the temperature reaches the maximum threshold value or not can be known conveniently, and in this way, the temperature can be detected in real time, and meanwhile, alarm of the temperature preset value and the marking of the maximum temperature threshold value can be realized, the over-temperature recording is realized, the subsequent temperature reduction pointer is still in the maximum threshold value marking state, the timely checking after the alarm is facilitated, and whether the temperature reaches a dangerous value or not can be known.

Description

technical field [0001] The invention relates to the field of industrial instruments, in particular to an electric contact bimetallic thermometer capable of self-power-off and alarm. Background technique [0002] The electric contact bimetal thermometer is used in the production site to automatically control and alarm the temperature. Directly measure the temperature of body, steam and gas medium in the range of -80~500℃ in various production processes. The characteristics of electric contact bimetallic thermometer: on-site temperature display, intuitive and convenient; with automatic power cut off and alarm function; safe and reliable, long service life Long; a variety of structural forms to meet different requirements. [0003] The current bimetallic thermometers use electric contacts to alarm the temperature range. However, for the use of different industrial equipment, there are high requirements for temperature. When the temperature exceeds the preset value, an alarm wi...
