[0003] Existing sensors are all fixed on the bracket. If the sensor is damaged, it will be difficult to replace. Moreover, the sensor needs to be fixed on the bracket with high shape accuracy and position accuracy. If the accuracy of the bracket cannot be guaranteed when the replacement is fixed, the position accuracy of the sensor will also decrease There is no guarantee, so the sensor may give false alarms when it is working, which will affect the normal operation of the equipment

Abstract
The invention discloses a high-reliability sensitive component, which structurally comprises a barrel, a filter screen and a sensor device, wherein the filter screen is arranged in the middle of the right side of the barrel, the sensor device is installed above the barrel, a fixing mechanism is arranged in a protection shell, the small-diameter section and the large-diameter section of a sensor are fixed to a position supporting mechanism, the large-diameter section is locked through a clamping mechanism, the middle section of the small-diameter section is erected in the middle of a supporting plate, the tail end of the small-diameter section is positioned and locked through a positioning mechanism, a conversion element is locked in the protection shell through a screw, a rubber cushion is compressed during locking so as to make the conversion element and the bottom end in the protection shell be in a seamless state to prevent a measurement data error caused by a hole seam in a working process, when the conversion element is locked, a switching circuit is attached to a power supply interface at the back end of a signal interface at the same time so as to achieve electric connection, and after the conversion element is locked, a cover plate covers and is locked by a screw so as to protect the fixing mechanism, so that the work is in a dust-free environment, and external dust pollution can be effectively prevented.
Description
technical field [0001] The invention relates to the field of sensitive components, in particular to a sensitive component with high reliability. Background technique [0002] Sensitive components are the abbreviations of sensitive components and sensor devices. They are usually called sensors in foreign countries. Sensors have already penetrated into extreme areas such as industrial production, space development, ocean exploration, environmental protection, resource investigation, medical diagnosis, bioengineering, and even cultural relics protection. broad field. [0003] Existing sensors are all fixed on the bracket. If the sensor is damaged, it will be difficult to replace. Moreover, the sensor needs to be fixed on the bracket with high shape accuracy and position accuracy. If the accuracy of the bracket cannot be guaranteed when the replacement is fixed, the position accuracy of the sensor will also decrease There is no guarantee, so the sensor may give false alarms whe...
