Description of the IP protection level of the electromagnetic flowmeter

Description of IP protection level for electromagnetic flowmeter
The degree of protection and IP (INGRESS PROTECTION) protection level system was drafted by IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION). The appliance is classified according to its characteristics of dustproof and moisture proof. The foreign objects referred to here include tools, human fingers, etc., which are not accessible to the electrified parts of the appliance, so as to avoid electric shock. The IP protection level is composed of two numbers. The first number indicates the level of the lamp from dust and the invasion of foreign objects. The second number indicates the level of the lamp's moisture-proof and waterproof intrusion. The larger the number, the more the protection level is. high.
The protection levels indicated by the two marked numbers are shown in Tables 1 and 2:
Digital protection scale interpretation
0 No protection No special protection for people or things outside.
1 Avoid intrusion of solid foreign objects larger than 50mm in diameter. Avoid touching the parts outside the appliance due to accidents, and avoid intrusion of foreign objects of larger size (greater than 50mm in diameter).
2 Avoid intrusion of solid foreign objects larger than 12mm in diameter. Avoid touching the fingers of the outside of the appliance with human fingers, and avoid intrusion of foreign objects of medium size (larger than 12.5mm in diameter).
3 Avoid intrusion of solid objects larger than 2.5mm in diameter. Avoid intrusion of tools, wires and similar small foreign objects with diameter or thickness greater than 2.5mm into parts outside the appliance.
4 Avoid intrusion of solid foreign objects larger than 1.0mm in diameter. Avoid intrusion of tools, wires and similar small foreign objects with diameter or thickness greater than 1.0mm into the parts outside the appliance.
5 Avoid foreign objects and dust. Completely avoid foreign matter intrusion. Although it cannot completely prevent dust from entering, the amount of dust intrusion will not affect the normal operation of the appliance.
6 Avoid foreign objects and dust. Completely avoid foreign objects and dust intrusion.

The second level of protection indicated by the feature number (number)
Digital protection scale interpretation
0 No protection No special protection against water or moisture
1 Avoid water intrusion Vertically falling water droplets (such as condensed water) will not damage the appliance
2 When the angle is 15 degrees, the water droplets can still be avoided. When the appliance is tilted vertically to 15 degrees, the dripping will not damage the appliance.
3 Avoid intrusion of sprayed water. Prevent rain or avoid water intrusion in the direction of vertical angle less than 60 degrees.
4 Avoid splashing water intrusion Avoid water splashing in all directions to invade the appliance and cause damage
5 Avoid intrusion of water from the radiation Avoid the intrusion of water from the nozzles in all directions into the appliance and cause damage.
6 Avoid large waves. Insects installed on the deck can avoid damage caused by large waves.
7 Avoid water intrusion when immersed in water. Electric appliances are immersed in water for a certain time or water pressure below a certain standard to ensure that no damage is caused by water immersion.
8 Avoid intrusion of water when submerged The appliance is submerged under the specified water pressure in an infinite period to ensure that it does not break due to water infiltration.
