Embodiment Construction
[0016] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.
[0017] Such as figure 1 , figure 2 As shown, the process method applied in the temperature sensor-relay is characterized in that activated carbon 6 is loaded into the temperature bulb induction tube 5 in the temperature bulb assembly of the temperature sensor, and the filter screen 4 is welded, and the filter screen 4 connects the capillary tube 2 It is separated from activated carbon 6 to prevent activated carbon particles from entering the capillary 2. The mesh number of the activated carbon particles is 8-16 mesh.
[0018] Put the air intake capillary and the ventilation capillary into the central rod 3 of the temperature bulb assembly, align the ends of the three, weld the filter screen 4 at the end of the central rod 3, and insert the end of the central rod 3 welded with the filter screen 4 into the temperature sensor that has been loaded w...

The present invention belongs to the technical field of a temperature sensor-relay and particularly relates to a process method applied to a temperature sensor-relay, and the problems that the sensitivity of an existing temperature sensor-relay is low and the grease temperature can not be precisely monitored. The whole temperature bulb sensing tube in the temperature bulb combination piece of the temperature sensor is loaded with activated carbon particles, a filter net is welded, the filter net separates capillaries from activated carbon, and the activated carbon particles are prevented from entering into the capillaries. According to the process, the purpose of the precise monitoring of the temperature in a diesel engine grease pipeline by the temperature sensor-relay is achieved. The process has the characteristics of low cost and strong practicability, can be promoted and applied in the same type of products, and has a large practical value. The process method can be widely used in the temperature sensor-relays of various fields, the purpose of precisely monitoring an ambient temperature is realized, and the prospect of marketing and application is wide.
Description
technical field [0001] The invention belongs to the technical field of temperature sensors-relays, and specifically relates to a process method applied in temperature sensors-relays, especially for temperature sensors-relays whose testing range is not greater than 50°C. Background technique [0002] In the lubricating oil pipeline of diesel engine, it is necessary to use the temperature sensor-relay to monitor the lubricating oil temperature. When the lubricating oil temperature reaches the set value of the pressure relay, the temperature sensor-relay will alarm, and the temperature sensor-relay will alarm if it is lower than the set value by 3°C~6°C , end the alarm. The traditional temperature sensor-relay is applied on the pipeline, and the temperature difference between the alarm switch off and on is greater than 6°C, that is, the alarm will continue when the lubricating oil temperature reaches the set value, and the alarm will end when the temperature drops above 6°C or ...
