1. The load cell in a high-temperature environment will cause problems such as melting of coating materials, solder joint openings and changes in the stress structure of elastomers. Load cells operating in high-temperature environments usually use high-temperature sensors; In addition, they must be insulated, water-cooled, or air-cooled, etc.

2. The effect of short circuit caused by dust and moisture symmetrical component sensors. Under these environmental conditions, sensors with high hermetically tightness should be used. Different sensors have different sealing methods, and they are very hermetic different. Ordinary seals are filled or coated with sealants; mechanical seal with rubber pads; Welding (TIG welding, plasma beam welding) and nitrogen vacuum. From the point of view of sealing effect, weld sealing is the best, and the amount of sealant filling is the difference. When it comes to sensors that work in both clean and boring environments, you can opt for rubber-sealed sensors. For those sensors that operate in wet, dusty environments, you should opt for a barrier heat seal or barrier weld seal.

3. In highly corrosive environments, such as short circuits caused by humidity and acidic load cells, sensors with good corrosion resistance and good sealing should be selected for plastic spraying or stainless steel external on the outer surface.

4. The influence of the output turbulence signal of the electromagnetic field symmetrical component sensor. In this case, the shielding of the sensor should be rigorously checked for good electromagnetic resistance.

5. Flammable and explosive, not only the symmetrical component sensor will be completely damaged, but also pose a huge threat to the safety of other equipment and personnel. As a result, sensors operating in flammable and explosive atmospheres place higher demands on explosion-proof functions: Explosion-proof sensors must be used in flammable and explosive environments. The sealing of such sensors should not only consider their tightness. It is also necessary to consider the explosion-proof strength, as well as the waterproof, moisture-proof, explosion-proof and so on of the cable leads.
