Which Environment Will Affect the Checkweighing Machine Sensor?

The checkweighing machine sensor also has requirements for the environment. If it is used in an inappropriate environment, some problems will occur. Next, let's talk about which environments will affect the checkweighing machine sensor.

1. The influence of electromagnetic field on sensor output disturbance signal

In this case, the shielding of the sensor should be strictly checked to see if it has good electromagnetic resistance.

2. In a highly corrosive environment

If moisture and acid cause damage to the elastic body or short circuit of the sensor, the outer surface should be sprayed with plastic or stainless steel outer cover, which has good corrosion resistance and good airtightness.

3. The influence of dust and humidity on the short circuit of the sensor

In this environmental condition, a sensor with high airtightness should be selected. Different sensors have different sealing methods, and their airtightness is very different. Common seals include sealant filling or coating; rubber gasket mechanical fastening seal; welding (argon arc welding, plasma beam welding) and vacuum nitrogen filling seal. From the perspective of sealing effect, welding and sealing is the best, and filling and coating sealant is poor in quantity. For sensors that work in a clean and dry environment indoors, you can choose a glue-sealed sensor. For some sensors that work in a humid and dusty environment, you should choose a diaphragm heat seal or a diaphragm welding seal, and Vacuum nitrogen filled sensor.
