Heat Flux Sensor,  for heat flux measurement

 

The Captec heat flow sensor measures the heat that passes through its surface.

Very thin and plate-shaped, this sensor is to be glued or applied to the surface on which the measurement is to be made.

Very easy to use the measured flow can be:

  • conductive only, case of a sensor in contact between two objects.

  • convective, case of a sensor installed on the surface and low emissivity.

  • convective and radiative, case of a sensor installed on the surface and high emissivity.

It will be said that this sensor measures the total flow taking into account its surface state.

​

These sensors are used in various fields such as

  • civil engineering

  • characterization of thermal insulation, concrete, ...

  • Fire test, UN 6C

  • thermal resistance measurements

  • thermal conductivity measurements

  • thermal comfort

  • education, practical work

  • chemistry

  • nuclear

  • solar

  • spatial

  • aviation

Very easy to use the heat flux sensor is linear, the output signal is a voltage proportional to the heat flux, the sensitivity remains constant, does not require power supply or cold junction compensation. It is a real differential sensor and the connection is made by two standard cables to connect directly to a voltmeter or measurement acquisition configured in DC voltage.

 

Each sensor is delivered calibrated in μV / (W / m2), mV / (kW / m2)

​

Captec  offers a range of standard sensors, square shapes and sizes between 5x5mm and 300x300mm.

​

The heat flux sensor can also be made according to specifications:

  • high temperature bonding

  • cryogenic bonding

  • resistant to pressure or vacuum

  • all forms according to diagram

  • with holes for screw passage

  • gold plated to ensure low emissivity

  • cooled sensor, on exchanger to measure high flows.

  • multi-zone sensor

  • sensor with guard area
