Key Benefits & Features

• Hydrogen‑Specific Calibration: Optimized algorithms account for the lower molecular weight and higher flame speed of hydrogen, providing accurate draft set‑points.
• Digital Display & Remote Access: 4‑digit LCD with Modbus‑TCP/RTU output lets you monitor the gauge locally or integrate it into SCADA/DCS systems.
• Wide Operating Range: -300 to +200 Pa (‑0.03 to +0.02 bar) covering the full spectrum of low‑pressure furnace drafts.
• Rugged Enclosure: IP66‑rated stainless‑steel housing (AISI 316L) resists corrosion from high‑temperature steam and occasional water wash‑down.
• Built‑In Diagnostics: Self‑test, sensor drift alert, and fail‑safe output (4‑20 mA) ensure continuous reliability.
• Compliance & Safety: Meets IEC 61010‑1, ATEX II 2G, and ISO 9001‑based quality management.

Application Scenarios

The gauge is engineered for the most demanding hydrogen boiler installations, including:

• Industrial Heat‑Treat Furnaces: Precise draft control reduces oxidation and improves surface finish on steel parts.
• Power‑Generation Boiler Rooms: Maintaining optimal draft prevents flame‑out and minimizes NOx formation.
• Chemical Process Reactors: Stable pressure ensures consistent residence time for hydrogen‑driven reactions.
• Marine and Offshore Platforms: Compact, explosion‑proof design meets confined‑space regulations.

Typical Specifications (customizable per order)

pressure gauge for high pressure hydrogen boiler

All dimensions, I/O configurations, and firmware options can be tailored to match your plant’s integration strategy. Our engineering team works directly with OEMs to ensure a seamless fit.

Competitive Advantages

While many generic pressure transmitters claim “high accuracy,” few address the unique thermodynamic behavior of hydrogen. Our gauge differentiates itself through:

• Hydrogen‑Optimized Sensor Matrix: Proprietary ceramic diaphragm maintains linearity across the low‑density gas.
• Fast Response Time: <1 s settling time enables real‑time draft adjustments during load ramps.
• Lifecycle Cost Savings: Integrated diagnostics reduce unplanned downtime, extending service intervals beyond 18 months.
• Global Support Network: 24/7 technical hotline, on‑site calibration service, and multilingual documentation.

Frequently Asked Questions

What is the minimum order quantity (MOQ) for a custom‑configured gauge?

Standard models start at a 1‑unit MOQ. For fully customized firmware or enclosure options, we typically require a minimum of 5 units to justify the engineering effort.

Can the device be integrated with existing SCADA platforms?

Yes. The gauge supports Modbus‑RTU, Modbus‑TCP, and Ethernet/IP out of the box. Custom driver scripts are available on request for proprietary systems.

What certifications does the digital draft gauge for hydrogen boiler furnace hold?

All units are IEC 61010‑1 certified, ATEX II 2G approved for explosive atmospheres, and manufactured under an ISO 9001‑based quality management system.

What warranty and after‑sales support are provided?

We offer a 24‑month limited warranty covering defects in materials and workmanship. During the warranty period, firmware updates and calibration services are provided at no additional charge.
