Product Overview

Our pressure gauge for high pressure hydrogen boiler is engineered to deliver precise, reliable readings in the most demanding hydrogen‑fuel environments. Built with stainless‑steel housing and a sealed‑beam design, the gauge resists corrosion, hydrogen embrittlement, and temperature extremes up to 300 °C. It integrates seamlessly into boiler control loops, providing real‑time feedback for safety interlocks, efficiency monitoring, and regulatory compliance. The device meets the rigorous standards of petrochemical, power‑generation, and industrial‑hydrogen sectors, ensuring uptime and protecting critical assets.

Each unit is supplied calibrated at 0 % and 100 % span, with optional differential output for advanced SCADA integration. The compact 80 mm diameter form factor fits standard 1/4‑in NPT ports, while the optional 1/2‑in port variant supports larger piping schemes.

Application Scenarios

The gauge is suited for a variety of high‑pressure hydrogen boiler installations, including:

• Utility‑scale power plants where hydrogen is used as a supplemental fuel.
• Industrial heat‑treatment furnaces employing hydrogen‑rich combustion.
• Hydrogen refueling stations that incorporate boiler‑based thermal management.
• Research labs testing next‑generation hydrogen boiler cycles.

In each case, the gauge’s high‑accuracy (±0.5 % of full scale) and robust sealing prevent leak‑induced safety incidents, while its quick‑response diaphragm tracks rapid pressure fluctuations typical of boiler load changes.

Industry Certifications & Safety

The gauge complies with the most widely recognized safety and quality programs for hydrogen service:

• ISO 9001:2015 – Quality Management Systems
• ISO 14001 – Environmental Management
• ATEX Zone 0/1 certification for explosive atmospheres
• IECEx approval for equipment used in hazardous areas
• ASME U‑Stamp for pressure equipment

All units undergo a three‑stage factory acceptance test (FAT) that includes leak‑rate verification, pressure‑cycling, and electronic signal validation. Documentation packages include a Calibration Certificate, CE Mark Declaration, and a detailed Material Traceability Report.

Frequently Asked Questions

What is the minimum order quantity (MOQ) for a custom‑spec pressure gauge for high pressure hydrogen boiler?

Our standard MOQ is 20 units for fully stocked models. For engineered‑to‑order configurations (e.g., special output signals or non‑standard port sizes) the MOQ reduces to 5 units, allowing you to prototype without large inventory commitments.

Can the gauge be integrated with existing PLC or DCS systems?

Yes. The device offers 4‑20 mA, 0‑10 V, and pulse‑width modulation outputs that are compatible with most PLC/DCS modules. We also provide wiring diagrams and firmware configuration files on request.

What are the typical lead times?

For standard catalog items, the lead time is 15‑25 working days after order confirmation. Custom engineered gauges require 30‑45 working days, depending on the complexity of the requested modifications.

What warranty and after‑sales support are provided?

All gauges come with a 24‑month limited warranty covering manufacturing defects. Our technical support team operates 24 × 7 on a regional basis, offering on‑site calibration assistance and spare‑part logistics when required.
