Description
The sensor of choice for cone calorimeters
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 water-cooled. 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.
State-of-the-art heat flux sensor
The SBG04 employs a novel sensor design that combines the benefits of traditional Gardon meter reed technology with those of traditional Schmidt-Boelter meter thermopile technology.
Several advantages
- Compatible with cone calorimeters
- All specifications and dimensions standardized to ISO 5660 and ASTM E1354
- Reduced diameter of 12.7 mm (0.5 in)
- Reduced installation height
- Tubes at a 90° angle to the body axis
- Scratch-resistant absorbent coating (reduced absorbent height)
- Safe storage with a convenient protective cap.
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 (see the brochure that can be downloaded on this page). Contact your cone
- calorimeter equipment supplier for an suitable mount or modification.
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.
Areas of Application
- Industrial monitoring and control / heat flux and heat transfer measurement
- Scientific research / heat and heat transfer measurement
