    FAQ

    Q 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 — suitable for various industrial installation requirements.
    Q What is the accuracy class of this pressure gauge?
    Accuracy class depends on the nominal diameter. Gauges with Φ40 to Φ63 conform to Class 2.5, while larger gauges from Φ98 to Φ250 offer higher precision at Class 1.0 or Class 1.6, making them ideal for applications requiring tighter measurement tolerances.
    Q What materials are used for the wetted parts and case?
    The wetted parts are made from 316L stainless steel as standard, with Monel available as an optional upgrade for highly corrosive media. The case is constructed from 304 stainless steel, with 316L stainless steel available as an option for more demanding environments.
    Q What ingress protection ratings does this gauge support?
    The BLD stainless steel pressure gauge supports IP54, IP65, and IP66 ingress protection ratings. This ensures reliable performance in dusty or wet environments, including outdoor installations and industrial processes with exposure to water jets or heavy contamination.
    Q What type of pressure sensing element is used?
    The pressure sensing element varies based on the operating pressure range. For pressures below 10MPa, a C-shape Bourdon tube is used. For pressures at or above 10MPa, a spiral tube is employed to ensure accurate and durable measurement under high-pressure conditions.
    Q How does ambient temperature affect the gauge's accuracy?
    When the ambient temperature deviates from the reference temperature of 20℃ ± 5℃, the indication error increases by no more than 0.04% per degree Celsius. The gauge is rated for ambient temperatures from -40℃ to 70℃ and media temperatures from -40℃ to 100℃, making it suitable for a wide range of operating conditions.
