SBG04 水冷式熱流センサー

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.

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.

Heat flux sensor with 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 Schmidt-Boelter gauges.

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.

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.

推奨用途

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.
