The YB Series All Stainless Steel Pressure Gauge is a mechanical pressure gauge with stainless steel shell and wetted parts. It is designed for pressure measurement of corrosive media and for working conditions where ordinary copper-alloy pressure gauges are not suitable.
The series can be used in petroleum, chemical, metallurgical, light industry, chemical fiber and other industrial sectors. It is also suitable for harsh working environments and locations with strong vibration.
- Pressure measurement of corrosive media.
- Petroleum, chemical, metallurgical and chemical fiber process applications.
- General industrial pressure indication under harsh working conditions.
- Sites requiring stainless steel shell and stainless steel wetted materials.
- Installations requiring bottom, back or flange-mounted pressure gauges.
- All stainless steel construction: Shell material and wetted material can be selected as 304SS or 316SS.
- Corrosion-resistant use: Suitable for corrosive process media where copper-alloy parts are not appropriate.
- Multiple protection options: IP55, IP65 and IP66 protection ratings are available.
- Wide pressure range: Vacuum, compound and positive pressure ranges are available.
- Flexible mounting: Radial, axial and flange mounting structures can be selected.
- Optional accessories: Damping device, heat dissipater, overpressure protector and subcooling pipe can be configured.
The working principle of the pressure gauge is that the Bourdon tube produces elastic deformation under the action of pressure or vacuum. This displacement is enlarged through a mechanical transmission mechanism and passed to the indicating device. The pointer indicates the measured pressure or vacuum value on the dial.
