Frequently Asked Questions

What nominal diameters are available for the BLD Stainless Steel Pressure Gauge? +

The BLD Stainless Steel Pressure Gauge is available in a wide range of nominal diameters: Φ40, Φ43, Φ50, Φ53, Φ63, Φ98, Φ100, Φ150, Φ200, and Φ250 mm, making it suitable for various industrial applications and installation requirements.
What is the accuracy class of the BLD pressure gauge? +

The accuracy class depends on the nominal diameter. Gauges with diameters Φ40 to Φ63 conform to Class 2.5, while larger gauges from Φ98 to Φ250 are available in Class 1.0 or Class 1.6, offering higher precision for demanding measurement applications.
What materials are used for the wetted parts and case of the gauge? +

The wetted parts are made from 316L stainless steel as standard, with Monel available as an optional material for highly corrosive media. The case is constructed from 304 stainless steel, with an optional upgrade to 316L stainless steel for enhanced corrosion resistance.
What type of pressure sensing element is used, and when does it change? +

For pressures below 10 MPa, a C-shape Bourdon tube is used as the sensing element. For pressures at or above 10 MPa, a spiral tube is employed to handle the higher pressure ranges safely and accurately.
What ingress protection ratings does the BLD pressure gauge support? +

The BLD Stainless Steel Pressure Gauge supports IP54, IP65, and IP66 ingress protection ratings. This makes it suitable for use in dusty, wet, and harsh outdoor environments where protection against water jets and solid particle ingress is required.
What are the operating temperature limits for the gauge and the media? +

The BLD pressure gauge operates within an ambient temperature range of -40℃ to 70℃. The media (process fluid) temperature is rated from -40℃ to 100℃. It is also important to note that when the ambient temperature deviates beyond 20℃ ± 5℃, the indication error remains at or below 0.04% per ℃.
