Description Vendor

The UV/IR Type RFD-2000X-H operates as a hydrogen detecting sensor designed for use in hazardous environments, utilizing a spectral response for both ultraviolet (UV) and infrared (IR) detection. Constructed from stainless steel 316 with physical dimensions of 134(W) x 117(D) x 120(H) mm, the sensor features an IP66/67 and NEMA Type 4X rated housing that ensures performance in harsh industrial conditions. The device delivers a detection range of 15m/49.5ft for n-Heptane and Hydrogen 32Plume across a 90° horizontal and vertical field of view with a typical response time of 5–10 seconds. It functions across an operating temperature range of -40℃ to +75℃, a storage range of -50℃ to +80℃, and relative humidity levels up to 95%. For seamless industrial integration, the unit features proprietary RS-485 communication, a 4–20mA output signal (IR Detection: 8mA ± 0.5mA, UV Detection: 12mA ± 0.5mA, Warning: 16mA ± 0.5mA, Alarm: 20mA ± 0.5mA), and relay alarm outputs rated at 2A at 28 VDC for fire, fault, and warning conditions. The sensor carries FM3260, IECEx, ATEX, and Ex d b IIB+H2 T6 approvals for certified hazardous area deployment.

Use Cases

  • Detecting hydrogen or hydrocarbon fires in hazardous industrial environments
  • Applicable in petrochemical, hydrogen storage, and fuel-cell facilities

Capabilities

  • Dual-spectrum UV/IR flame detection
  • Detects hydrogen and n-heptane flame events
  • Built-in RS-485 + analog 4–20 mA signal output
  • Certified for hazardous zones (ATEX, IECEx, FM)
Rezontech Co., Ltd. Rezontech is a South Korean company specializing in flame detection technology, particularly in hydrogen economy applications. It manufactures advanced flame detectors and disaster prevention systems. Rezontech has earned numerous certifications and supplies its technology globally.
