  2. Heat flux sensor - Wikipedia

    en.wikipedia.org/wiki/Heat_flux_sensor

    Typical heat flux plate, HFP01. This sensor is typically used in the measurement of the thermal resistance of and heat flux on building envelopes (walls, roofs). Also, this sensor type can be dug in to measure soil heat flux. Diameter 80 mm Heat flux sensor mounted on a window. Heat flux sensors can be used like this to determine the R-value or ...

    en.wikipedia.org/wiki/Cone_calorimeter

    However, prior devices used to measure heat release typically estimated the heat release of a fire by measuring the increase in temperature of ambient air flowing past the combusting material and these measurements of heat release were often inaccurate, so a more reliable device was desired.

  4. Calorimeter - Wikipedia

    en.wikipedia.org/wiki/Calorimeter

    A calorimeter is a device used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity. Differential scanning calorimeters, isothermal micro calorimeters, titration calorimeters and accelerated rate calorimeters are among the most common types. A simple calorimeter just consists ...

  5. Duct leakage testing - Wikipedia

    en.wikipedia.org/wiki/Duct_leakage_testing

    A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow.

    They are also used widely in heat flux sensors and pyrheliometers [5] [6] and gas burner safety controls. The output of a thermopile is usually in the range of tens or hundreds of millivolts. [7] As well as increasing the signal level, the device may be used to provide spatial temperature averaging. [8]
