The pressure gauage is to check thepressure of the water or air pressure. The main pressure range is 0-6bar. It canbe radial direction or axial direction.
Pressure gauges are instruments that measure the difference in pressure within a system and atmospheric pressure. A pressure gauge is a measurement device which determines the pressure in a compressed gas or liquid. Pressure gauges, like all measuring tools, have a tendency to wear over time and may become less accurate. Pressure gauges are widely used all over the world, for tasks ranging from checking the tire pressure in a car before a trip to monitoring the pressure of various systems inside a nuclear power plant.
