User Manual Instructions
There are 6 models of SBG01
SBG01 measures heat flux in the range of (5 to 200) 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. Using an open detector, SBG01 is also sensitive to convective heat flux. This contribution is usually ignored. Application in environments with lower than 50 x 103 W/m2 irradiance levels or environments with significant heat transport by convection is possible but requires a careful evaluation of the measurement uncertainty. SBG01’s thermopile sensor generates an output voltage proportional to the incoming irradiance. The sensor is water-cooled. There are 6 models of SBG01; each with a different rated measurement range, calibration reference irradiance level, sensitivity and response time. Water cooling is usually supplied by tap water. There are several optional body designs. The standard body is equipped with a flange. Common options are a smooth cylinder body without a flange (model -C) and threaded body (model –T). Also a thermocouple (type T or K) can be fitted upon request.
1、Robust and serviceable water tubes
2、Scratch resistant absorber coating (slightly lowered surface)
3、Safe storage with a practical protection cap
4、Durable cable with strain relief, temperature resistant up to 200 °C
SBG01 has rapidly become the sensor of choice for fire testing. SBG01 is mainly used to test reaction to fire and fire resistance. It is also used as a calibration reference standard for test equipment for example in flammability and smoke chamber tests
