Thermal Sensors Water-cooled heat flux sensor – for cone calorimeters SBG04 is a water-cooled sensor that measures heat flux. SBG04 is mainly used as a calibration reference standard for testing with cone calorimeters. All specifications and dimensions are standardised for use in cone calorimeters according to ISO 5660 and ASTM E1354 reaction-to-fire tests. The design includes two water cooling tubes fixed at a 90° angle to the sensor body, with a sensor body of a 0.5 inch diameter. The sensor may also be used in flammability, fire resistance, and smoke chamber testing. For other water-cooled heat flux sensors, see the SBG01 and GG01 sensors. Figure 1 SBG04 water-cooled heat flux sensor. Introduction SBG04 measures heat flux in the range of (10 to 100) x 103 W/m2. Equipped with a black absorber, heat flux sensors of this type are designed for measurement in an environment in which heat flux is dominated by radiation. SBG04’s thermopile sensor generates an output voltage proportional to the incoming irradiance. The sensor is watercooled. Water cooling is typically supplied by tap water connected to the stainless steel in and outlet tubes. These tubes stand at a 90° angle to the 0.5 inch diameter cylindrical sensor body axis, and parallel to the black sensor surface as required for testing with cone calorimeters. Next level technology SBG04 employs a novel sensor design, which combines the benefits of foil technology of the traditional Gardon gauges with those of the thermopile technology of traditional SchmidtBoelter gauges. SBG04 has several advantages: • cone calorimeter compatible • all specifications and dimensions standardised according to ISO 5660 and ASTM E1354 • reduced diameter of 12.7 mm (0.5 inch) • reduced installation height • tubes at 90° angle to the axis of body • scratch resistant absorber coating (reduced absorber height) • safe storage with a practical protection cap. Suggested use SBG04 is the sensor of choice as calibration reference standard for cone calorimeter test equipment, in accordance to ISO 5660 and ASTM E1354 reaction-to-fire tests. It is also used in flammability, fire resistance and smoke chamber tests. Copyright by Hukseflux. Version 2305. We reserve the right to change specifications without prior notice Page 1/5.

Thermal Sensors Measurement uncertainty The uncertainty of the measurement with SBG04 should be determined case by case. It is a function of: 1. heat flux sensor properties. 2. uncertainty of calibration and quality assurance of the local calibration reference standard. 3. verification of the stability of SBG sensors in day to day measurements, before and after use. 4. application-related uncertainties, for example caused by the unknown contribution of convection and the representativeness of the measurement location. Hukseflux provides a traceable calibration. The reference standard at...

Thermal Sensors SBG04 mounting To position SBG04 according to the standard practise of ISO 5660 and ASTM E1354 a “flux meter mount” shall be used. The recommended dimensions for the slot in the mount for SBG04 are provided in figure 4. Contact your cone calorimeter equipment supplier for an suitable mount or modification. Figure 4 Suggested slot dimensions for SBG04 cone calorimeter “Flux meter mount”. SBG01 water-cooled heat flux sensor with a 1 inch body for measurements < 200 x 103 W/m2. GG01 Gardon gauge water-cooled high heat flux sensor for measurements > 250 x 103 W/m2. HFS01 is a...
