causesensorThe impact on the environment mainly includes the following aspects:
　　
1) Dust and moisturesensorCausing the impact of a short circuit. Under these environmental conditions, sensors with high airtightness should be selected. The sealing method of the same sensor is the same, but there are significant differences in its sealing performance.
　　
Common seals include sealant filling or coating; Rubber pad mechanical fastening seal; Welding (argon arc welding, plasma beam welding) and vacuum nitrogen sealing.
　　
From the perspective of sealing effect, welding sealing is the worst, while filling and applying sealant is the worst. For sensors working in clean and dry indoor environments, adhesive sealed sensors can be selected, while for sensors working in humid and dusty environments, diaphragm hot sleeve sealing or diaphragm welding sealing, vacuum filling and nitrogen filling sensors should be selected.
　　
2) High temperature environmentsensorCausing problems such as melting of coating materials, cracking of solder joints, and structural changes in the stress inside the elastomer. High temperature resistant sensors are often used for sensors working in high-temperature environments; In addition, insulation, water cooling or air cooling devices must be added.
　　
3) In highly corrosive environments such as humidity and aciditysensorIf it causes damage to the elastic body or short circuits, the outer surface should be coated with spray coating or rust steel cover, which has good corrosion resistance and good sealing performancesensor.
　　
4) Flammable and explosive are only applicable tosensorCausing sexual damage and posing a significant threat to other devices and personal safety. Therefore, working in flammable and explosive environmentssensorHigher requirements have been put forward for explosion-proof performance: explosion-proof must be selected in flammable and explosive environmentssensorThis kind ofsensorThe sealing cover only needs to consider its airtightness, as well as its explosion-proof strength, waterproof, moisture-proof, and explosion-proof properties for cable leads.
　　
5) Electromagnetic fieldsensorThe impact of outputting chaotic signals. In this situation, respond tosensorStrictly inspect the shielding performance to see if it has good electromagnetic resistance.
