Universal Heat Flow Sensors

Product catalog summary
Overview: The document provides detailed information about Universal Heat Flow Sensors manufactured by WUNTRONIC GmbH, designed for use in industry, laboratory, and research settings. The models covered include HFS50, HFS15, HFS20, HFR25, HDSM16, HFRM16, HFSRM10, and HFRM10.
Description: These sensors measure heat flow by creating a temperature gradient that generates a voltage proportional to the heat flow. The readout is obtained by multiplying this voltage with the sensor's calibration constant.
Specifications:
  • Heat Flux Range: 9.5 kWm-2
  • Temperature Range: -30°C to +150°C
  • Thermal Conductivity: 0.316 Wm-1K-1
  • Accuracy: ±5%
  • Linearity: ±2%
  • Environmental Resistance: Waterproof and impervious to pressure or vacuum
  • Heat Flux Direction: Bidirectional
Features:
  • Direct heat flux readout
  • Measures bidirectional heat flow
  • Sensitivity unaffected by vacuum
  • Self-generating output, no amplifier or power supply needed
  • Easy installation
Applications: Suitable for green roofs, soil, insulation evaluation, submarines, vessels, biomedical research, and laboratories.
Optional Temperature Sensors: Thermocouple type K or T and NTC sensors are available. Calibration is traceable to NIST, with optional temperature sensor calibration.
Ordering Information: Sensors can be ordered with optional temperature sensors and longer cables. The nomenclature includes sensor type, temperature sensor type, and cable length.
Cables and Wiring: Sensors come with a 1m cable. Different cable types are used depending on the presence of temperature sensors, with options for longer cables and different coatings available upon request.

The temperature gradient perpendicular to the sensor surface generates an equivalent voltage. The heat flow readout of the sensor is the voltage multiplied with the calibration constant of the sensor. Green Roof and Soil Insulation evaluation of Roofs, Walls ect.
