Detail HUKSEFLUX – SBG01
Product Description
SBG01 is a water-cooled heat flux sensor. The ISO standards call this a heat flux meter. Its main purpose is the study of reaction to fire and fire resistance, applied for instance in flammability tests and smoke chamber tests. SBG01 measurements are in accordance with various ASTM and ISO standards. SBG01 is on the market since 2008, and has rapidly become the sensor of choice for fire testing laboratories.
SBG01 serves to measure the heat flux in the range up to 200 kW/m2. Heat flux sensors of this type are originally designed to work in an environment that is dominated by radiation (so above 50 kW/m2). Application in environments with lower irradiance levels and with much convection should be done with care. Working completely passive, using a thermopile sensor, SBG01 generates an output voltage proportional to the incoming flux. The sensor is water cooled. There are 6 types of SBG01; with different working range, sensitivity and response time.
Comparing to traditional Gardon and Schmidt Boelter gauges, SBG01 has several advantages:
tubes with increased robustness
increased scratch resistance of absorber paint (slightly lowered surface)
practical protection cap
