HFS01 High Heat Flux Sensor
The HFS01 sensor can also be ordered without black coating, so that HFS01’s absorption of radiation is reduced, while it remains sensitive to convective radiation. Users may also coat HFS01 with their own coating, to create a different response to radiation.
HFS01 has several advantages:
- very robust all-metal / ceramics instrument body and sensor
- high-temperature signal cable
- signal wires electrically insulated from the sensor body and from cooling water
Using HFS01 is easy. It can be connected directly to commonly used data logging systems. The heat flux, in W/m², is calculated by dividing the HFS01 output, a small voltage, by the sensitivity. The sensitivity is provided with HFS01 on its product certificate. Equipped with heavy-duty cabling and a fully stainless steel casing which prevents moisture from penetrating the sensor, HFS01 has proven to be very reliable.
HFS01 calibration is traceable to international standards. The factory calibration method follows the recommended practice of ASTM C1130-07 (2012).
