The protection and sealing of the weighing sensor is the fundamental guarantee for stable and reliable work under the influence of the objective environment and induction environment conditions. Therefore, it is an important process in the manufacturing process. The protection and sealing technology and process must be advanced, reasonable and reliable.

The protection and sealing level of the weighing sensor is an important project in its technical parameters, generally represented by IP plus numbers, different numbers represent what does it mean, this article Zhihe technology with you to take a look.

The international common protection standard system is represented by 3 numbers in sequence, which respectively represent dust-proof, moisture-proof (or waterproof), and impact resistance. Because the weighing sensor itself has the ability to resist vibration and impact, the third digit is omitted and only two digits are used to express it. The 2-digit representation of IP protection and sealing system is as follows:

The first digit indicates the dust-proof grade： 

0 -- No protection;

1 -- Protect solid particles to 50mm;

2 -- Protect solid particles to 12mm;

3 -- Protect solid particles to 2.5mm;

4 -- Protect solid particles to 1.0mm;

5 -- Enter the dust-proof range (basic dust-proof);

6 - Completely dust-proof.

The second digit indicates the moisture (or waterproof) rating： 

0 -- No protection;

1 -- Protection of vertical descending water;

2 -- Protect the direct injection of incoming water from the vertical direction up to 15 degrees;

3 -- Protection against direct injection of incoming water from the vertical direction up to 60 degrees;

4 -- Protection of direct injection of incoming water in a full range;

5 -- The protective water is sprayed from the low-pressure nozzle;

6 -- The protective water is sprayed from the high-pressure nozzle;

7 -- Protective water depth between 15cm ~ 1m;

8 -- Protection under pressure for a long time immersion.
