Steam Pressure Gauge for Coal Boiler Wholesale – Precision Monitoring for Power‑Generation Plants
When you source a steam pressure gauge for coal boiler wholesale, you demand reliability, accuracy, and compliance under the toughest operating conditions. Our gauges are engineered for continuous duty in coal‑fired boiler systems, delivering exact pressure read‑outs that safeguard equipment, optimise fuel consumption, and meet stringent safety regulations. Whether you are a plant‑owner, EPC contractor, or regional distributor, our solutions integrate seamlessly into your existing control loops and reduce downtime caused by measurement errors.
Application Scenarios – Where Precision Matters
- Main‑steam header of 30–150 t/h coal boilers in utility power stations.
- Super‑heater and reheater pressure verification in combined‑cycle units.
- Safety‑relief valve set‑point verification for compliance with ASME Section II.
- Remote monitoring stations in distributed generation sites where harsh environments demand robust construction.
- OEM integration for custom‑built boiler modules supplied to international manufacturers.
Key Benefits & Competitive Advantages
• High‑accuracy dial: ±0.25 % of full scale, verified by calibrated reference standards.
• Corrosion‑resistant housing: 316L stainless steel with ceramic window to withstand flue‑gas acidity and high humidity.
• Extended temperature range: –20 °C to +250 °C (‑4 °F to +482 °F), suitable for boiler rooms and outdoor installations.
• Explosion‑proof certification: Conforms to IECEx and ATEX Zone 1/2 requirements, eliminating the need for additional protective enclosures.
• Long‑life diaphragm: Viton® seal that resists oil, soot, and coal‑dust ingress for up to 10 years of continuous service.
• Modular wiring options: 4‑20 mA, HART, or Modbus output for integration with SCADA and DCS platforms.
• OEM/ODM flexibility: Custom dial faces, branding, and mechanical dimensions available without tooling cost for orders over 500 pcs.

FAQ – Quick Answers for Procurement Teams
What is the minimum order quantity (MOQ) for wholesale pricing?
Our standard MOQ is 200 units per model. For larger projects (≥500 pcs) we can provide tiered discounts and free engineering support for custom dial faces.
Can the gauge be calibrated to a different accuracy class?
Yes. While the default is ±0.25 % FS, we offer ±0.1 % FS for high‑precision loops at an additional cost and longer lead time (typically +15 days).
What is the typical lead time for a bulk order?
Standard gauges ship within 15–30 days after order confirmation. Custom configurations (e.g., unique dial graphics or non‑standard output) require 30–45 days depending on complexity.
Do you provide warranty and after‑sales support?
All units carry a 24‑month limited warranty covering manufacturing defects. Our technical service team is available 24 × 7 for troubleshooting, calibration assistance, and spare‑part supply.
