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
