Stainless steel pressure gauge's matters needing attention

Stainless steel pressure gauge degree of protection

IP54; IP55; IP65; IP66

IP protection level is composed of two numbers. The first number represents the level of dust prevention and prevention of foreign invasion; The second number indicates the tightness against moisture and water intrusion. The larger the number, the higher the protection level. The protection level represented by the two marked numbers is described as follows:

IP54 features: dustproof and waterproof.

The first letter 5 stands for dust prevention; The second letter 4 represents: prevent the invasion of splashing water,

IP55 features: dustproof and waterproof.

The first letter 5 stands for dust prevention; The second letter 5 represents: prevent the intrusion of sprayed water,

IP65 has good shock resistance and sealing performance; Advantages: dustproof and water spray proof. It is used for shock resistant and explosion-proof instruments and occasions with harsh on-site environment.

The first letter 6 represents dust seal and dust seal. The second letter 5 represents: water spray,

IP66 features: dustproof and waterproof.

The first letter 6 represents dust seal and dust seal. The second letter 6 stands for preventing the invasion of big waves.

The shock gauge of IP65 contains an explosion-proof plug. The function of the explosion-proof plug is to prevent the medium from ejecting from the front of the pressure gauge due to excessive pipeline pressure, so the explosion-proof plug is installed at the back.

Stainless steel pressure gauge installation precautions

1. The selection of pressure measuring points can reflect the real situation of the measured pressure.

(1) It should be selected at the pipe section where the measured medium flows in a straight line, not at the bend, bifurcation, dead corner or other places where vortex is easy to form.

(2) When measuring the pressure of flowing medium, make the pressure point perpendicular to the flow direction, and remove the drilling burr.

(3) When measuring the liquid pressure, the pressure point shall be at the lower part of the pipeline so that no gas is accumulated in the impulse pipe. When measuring the gas, the pressure point shall be above the pipeline so that no liquid is accumulated in the impulse pipe.

Stainless steel pressure gauge instructions for use and ordering

(1) The shockproof stainless steel pressure gauge is not suitable for the environment with chlorine, nitric acid, oxygen perchloride and other enhancers.

(2) When the shell of stainless steel pressure gauge needs to be sprayed with PTEE Teflon coating, it shall be indicated when ordering.

(3) If special requirements are required for the joint thread of stainless steel pressure gauge, please specify.

(4) All stainless steel pressure gauges are divided into ordinary type and shock resistant type.

(5) Please specify the name, model and upper limit of measurement when ordering
