The high temperature environment causes problems such as melting of coating materials, opening of solder joints, and structural changes in the stress inside the elastic body of the sensor. 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.

Dust and moisture can cause short circuits in sensors. Sensors with high airtightness should be selected under these environmental conditions. Different sensors have different sealing methods, and their sealing performance varies greatly.

The sealing and protection of weighing sensors commonly include sealant filling or coating, rubber pad mechanical fastening sealing, welding (argon arc welding, plasma beam welding), and vacuum nitrogen filling sealing. From the perspective of sealing effect, welding sealing is the best, and filling and coating with sealant is the difference in quantity. For sensors working in clean and dry indoor environments, adhesive sealed sensors can be selected. For sensors working in humid and dusty environments, membrane heat sealed or membrane welded sealed sensors, vacuum filled nitrogen filled sensors should be selected.

In highly corrosive environments, such as humidity and acidity, which can cause damage to the elastic body of the sensor or cause short circuits, sensors with good corrosion resistance and airtightness should be selected with an outer surface sprayed with plastic or stainless steel cover.

Flammability and explosiveness not only cause thorough damage to sensors, but also pose a significant threat to other equipment and personal safety. Therefore, sensors operating in flammable and explosive environments have higher requirements for explosion-proof performance: explosion-proof sensors must be selected in flammable and explosive environments. The sealing cover of such sensors not only needs to consider their airtightness, but also their explosion-proof strength, as well as the waterproof, moisture-proof, and explosion-proof properties of cable leads.
