The SB2000 Schmidt-Boelter heat flux sensor is particularly good at measuring low heat flux levels and convective heat flux.
The Schmidt-Boelter range of heat flux sensors complements the Thermogage heat flux sensors. Schmidt-Boelter heat flux sensors should be chosen over the Thermogage heat flux sensors in a number of circumstances:
In order to preserve measurement accuracy, the measurement surface should be kept clean. The sensors are suitable for use in an outdoor environment and are shower proof. It is recommended that the sensor be covered and protected from the weather when not in use. However, note that rainwater on the measurement surface will spoil any measurements taken.
The only thing about this sensor that needs to be specified is the mechanical package. There are links to some of the more popular packages on this web page, but other designs are possible. Please tell us your requirements and we will do our best to accommodate your mechanical requirements.
Minimum standard diameter of 0.25"
Minimum standard length of 0.5"
Transducer Calibration Accuracy: ±3% of full scale
Minimum Sensitivity: 150 µV/W/cm²
Time Response: 500mS
Nominal Resistance: 100 Ohms
Maximum temperature: 200°C
Maximum continuous heat flux: 10 W/cm² (with a good heat sink)
Maximum transient heat flux: 20 W/cm²
Please note that there is a temperature dependency with Schmidt-Boelter heat flux sensors. The sensitivity increases roughly 0.1% per °C. For this reason, it is recommended that the SB2000 be fitted to a large heat sink, or that the water cooled SB1000 be used.
