Explosion-proof markings cover Ex d ⅡBT6, Ex d ⅡCT4, Ex ia ⅡCT6, etc. Applicable to Zone 1 and Zone 2 explosive gas environments, Class IIB and IIC gas groups, and T1~T6 temperature groups, meeting strict safety standards for high-risk petroleum and gas industries.
Constructed entirely of stainless steel from outer casing to measuring elements. Built to withstand weak acids, weak alkalis, and salt spray. Waterproof and dustproof design makes it suitable for harsh coastal and chemical workshop environments.
Accuracy class reaches ±1.0% FS to ±1.6% FS with coverage from vacuum ~0.1MPa up to 0~100MPa. Silver alloy contacts offer strong anti-ablation capability and sensitive response, allowing direct interlock with relays, PLCs, and solenoid valves.
Supports radial, axial, and axial with edge mounting options. Interface threads include NPT, BSP, and ZG specifications. Select models support custom diaphragm sealing structures for viscous and particulate media measurement.
The gauge features explosion-proof markings including Ex d ⅡBT6, Ex d ⅡCT4, and Ex ia ⅡCT6. It is designed for Zone 1 and Zone 2 hazardous gas environments.
Connection locations include Lower, Center Back, and Lower Back. Standard thread options cover 1/8", 1/4", 3/8", and 1/2" across NPT, PT (BSPT, ZG), and BSP (G, PF) formats.
The measuring element (Bourdon Tube), internal movement, and connection are all constructed from high-grade stainless steel to ensure high durability and corrosion resistance.
Yes. Equipped with silver alloy contacts, it provides fast on/off response that can directly link with relays, PLCs, and solenoid valves for automatic pressure control and safety interlocks.
Its stainless steel construction handles weak acids, alkalis, and salt spray. For viscous or particulate media, customized diaphragm sealing structures are available.
The gauge offers an accuracy class of ±1.0% FS to ±1.6% FS, with measurement spans covering vacuum ~0.1MPa up to high-pressure ranges of 0~100MPa.
