Description Vendor

The MODEL5100 is a fixed point hydrogen leak detector for industrial and commercial installations. It uses palladium-alloy thin-film technology to provide hydrogen-specific detection without cross-response from other combustible gases. Hydrogen is measured over 0–100% LEL with ±5% full-scale accuracy and a response time below 30 seconds. The detector is designed for permanent leakage monitoring across hydrogen production, storage and transport, fuel-cell and related industrial environments. It includes pressure compensation, relay output, 4–20 mA, RS232/RS485, Modbus RTU, IP66 protection and optional audible/visual alarm.

Use Cases

  • Hydrogen production leak monitoring
  • Hydrogen storage leak monitoring
  • Hydrogen transport safety
  • Fuel-cell installation safety
  • Industrial fixed-point hydrogen monitoring

Capabilities

  • Detects hydrogen leakage continuously at fixed locations
  • Triggers relay and optional alarm outputs
  • Compensates for process pressure variation
  • Integrates with control and monitoring systems through analog and digital interfaces
Hydrogen Sense Technology Co., Ltd. Hydrogen Sense Technology Co., Ltd. develops and manufactures palladium-alloy thin-film hydrogen sensors, transmitters and online analyzers. Its manufacturing capability includes MEMS thin-film sensor-chip design, fabrication, packaging and test equipment, with dedicated hydrogen-sensing products for hydrogen production, storage, transport, fuel-cell and industrial gas-monitoring applications.
