Why oil filled pressure gauge on the joint with a channel slot

The axial oil filled pressure gauge on the joint: why do you want to bring a channel slot? Below small make up to you answer: axial oil filled pressure tapping on a channel slot can be stuck with a diamond clip, bolt on reload, easy on the machinery and equipment. So after installation in severe vibration environment place, not easy to fall off. Instrument stability and clear stability. Long service life. Working principle: the pressure gauge by sensitive element (in the table Bourdon tubes, bellows, bellows) Elastic deformation, the pressure deformation by the transformation of movement in table to Pointers, cause the hands to display the pressure. Pressure gauge is the main purpose of the oil filled in order to reduce pointer in relatively large variations in pressure buffer to zero, so that we can effectively ensure the sensitivity of pressure gauge. Applicable to the environmental vibration place, can tolerate the pulsation of the medium, impact and sudden unloading, guarantee the stability of instrument is clear.
