MF-180 Heat flux sensor

  • Thin heatflux sensor
  • High sensitivity
  • Small size
  • Calibration complies with JIS A 1412

The MF-180 is a thin, sensitive, heat flux sensor. Small and easy to handle, the MF-180 is easy to attach to and detach from a range of surfaces. It can measure medium to low heat flux values, and is suitable for a range of applications; with a measurement range from -30 C֯ to 120 C֯.

Heat flux sensor is a thermopile, an electronic device that translates thermal energy into electrical voltage proportional to the temperature gradient across its thermocouples’ hot and cold junctions. To generate a high enough measurable voltage, heat flux sensors are equipped with multiple thermocouple junctions connected in series, distributed over the area of the sensor.

EKO Instruments offers a selection of thin substrate heat-flux sensors, in a range of different sizes and thicknesses; an ideal option for research and engineering applications as well as manufacturing control and monitoring processes.
