High-temperature heat flux sensor IHF03

calibrationmonitoringR&D

IHF03 — ultra‑sensitive industrial heat flux sensor for precise heat flux and surface temperature measurement.

Overview
The IHF03 is designed for high‑sensitivity heat flux measurements and thermal performance assessment in industrial and research environments. It combines a thermopile heat flux sensor with an integrated Type K thermocouple and a stainless‑steel housing with a micro breather for pressure equalization.

Available cable options

• No cable
• 1 m (3.2 ft)
• 5 m (16.4 ft)
• 10 m (32.8 ft)
• 20 m (65.6 ft)
• 30 m (98.4 ft)
• 50 m (164 ft)
• 80 m (262.4 ft)

Key features

• Very high sensitivity (nominal 250 × 10⁻⁹ V/(W/m²)).
• Integrated thermopile for heat flux and Type K thermocouple for temperature.
• Stainless‑steel housing with micro breather to mitigate pressure differences.
• Sensor and high‑temperature cable rated up to 850 °C (standard).
• Designed for dry industrial environments (not for continuous wet, humid or chemically aggressive environments).
• Optional accessories: magnetic mounting frame, optional black coating, high‑ and low‑temperature cable variants.

Applications

• Scientific research and heat transfer measurement
• Industrial process monitoring (furnaces, boilers, ovens, fluidized beds, reduction cell shells)
• Building physics and insulation performance assessment
• Fire and flammability testing
• Validation of thermal CFD simulations

Operation

• Output voltage is proportional to heat flux: heat flux (W/m²) = output voltage / sensitivity (sensitivity given on calibration certificate).
• Temperature output provided by the integrated Type K thermocouple.
• Connects directly to standard data logging systems; signal wires are electrically insulated from the sensor body.
