Suitable for Long Term Use at One Location as well as Repeated Installation
The sensors inside HF01, a thermopile and a thermocouple, are protected by fully sealed stainless steel body. It is suitable for long term use at one location as well as repeated installation when a measuring system is used at multiple locations. HF01 measures heat flux through the object on which it is mounted, in W/m², as well as its surface temperature in °C. The sensors in HF01 are a thermopile and a type K thermocouple. The thermopile measures the local heat flux. The thermocouple measures the absolute temperature of the surface on which HF01 is mounted, as well as the approximate sensor body temperature. A thermopile and a thermocouple are passive sensors; they do not require power. The part of the cabling closest to the sensor is a special high-temperature metal sheathed cable with an interlocked spiral stainless steel armour. The sensor as well as the high temperature cable and armour withstand temperatures up to 800 °C. The temperature range is reduced to 600 °C in case the black coating is used, to 550 °C in case the frame with magnets is used.
Easy to Use
Using HF01 is easy. It can be connected directly to commonly used data logging systems. The heat flux, in W/m², is calculated by dividing the HF01 output, a small voltage, by the sensitivity and by applying a linear correction based on the temperature measurement. The sensitivity and temperature dependence are provided with HF01 on its product certificate. Equipped with heavy duty cabling, and having a fully stainless steel casing so that moisture does not penetrate the sensor, HF01 has proven to be very reliable. It survives long-term outdoor installation and repeated installation using the frame with magnets.
