Product Description
Over Pressure Protector
It is used to protect pressure gauges, pressure transducers and other pressure measuring instruments under the case of pressure rising rapidly, in order to guarantee the pressure will not exceed maximum range.
Theory
Use bellows and adjustable springs to set pressure limit value. Bellows or pistons are equipped with pressure shut down system. Pressure gauge will be automatically shut down from process medium when over-pressured. When the pressure is below the limit value, connection will be resumed.
Element: Bellow (High pressure: Piston)
Adjustable Pressure Range:
0.04~0.08MPa 0.15~0.3MPa 0.4~1.6MPa
0.06~0.15MPa 0.2~0.6MPa 1.0~4MPa
0.08~0.2MPa 0.3~1MPa 0.6~2.5MPa
Protector Pressure Resistant Value:
High pressure system: 30Mpa (Piston)
Medium pressure system: 16MPa
Low pressure system: 2.5MPa
Process Medium: Gas or liquid
Materials: Stainless steel, 1Cr18Ni9Ti 0Cr18Ni12Mo2Ti, connection thread will be decided by customers, standard size is M20× 1.5
Accuracy Class: 1.5
