Heat Flux sensor

At the Pyramid Laboratory - Observatory the DPE260 Lsi-Lastem Heat flux sensor is installed.

Heat flux sensors are used for measuring thermal flux, i.e. the quantity of energy that passes through the sensor itself.

A thermopile, inserted within the heat flux, measures the small temperature difference that forms between its two sides due to thermal resistance. These sensors have direct outputs and are supplied with calibration certificates.

The technical characteristics are:

- Sensitive element: Thermopile

- Measurement range: <2000 Wm-2

- Electric output: 8..14 Wm-2

- Impedance: 400..500 ohm

- Accuracy: 3%

- Non-linearity: <1,5%

- Th.drift (-10+40°): <2%

- Response time (63%): 2min 5 min

- Operative temp: -40°+80°C.

- Therm. Conductivity: 0,5 W/m°C

- Thickness: 7 mm

- Ø total: 50 mm

- Ø active :15mm

- Output cable: 2 mt

- Weight (no cable): 50 gr
