This heat flux can have different origins; in principle convective- radiative- as well as conductive heat can be measured. Heat flux sensors are known under different names, such as heat flux transducers, heat flux gauges, heat flux plates.

Design, fabrication and characterization of thin film resistances for heat flux sensing application Article in Sensors and Actuators A Physical April with Reads How we measure 'reads'. heat flux sensor. The design considerations for heat flux sensors of this type have been addressed in the literature [22, 28].

Of major importance is the sensitivity of the measurement (both temperature and heat flux), self-heating within the sensor, and the thermal resistance imposed on the surface to be measured.

These effects are a combination of a fast response to an initial thermal flow and a slower response to heat dissipation or accumulation. The sensitivity and accuracy of HTS SQUIDs are limited at low frequencies by magnetic flux (vortex) penetration into HTS thin-film structures.

and new cutting-edge design approached for improved. A readout is accomplished by connecting a sensor to any direct reading dc microvoltmeter or recorder. The HFS series sensor is designed for precise measurement of heat loss or gain on any surface.

It can be mounted on flat or curved surfaces and employs butt-bonded junctions with a very low thermal profile for efficient reading. The measurement of thermal properties or internal or external boundary conditions requires temperature and heat flux data.

Both information can be provided by heat flux sensors. The one consisting in measuring temperature at various locations within the wall and using inverse method to estimate wall temperature and heat flux is among those providing the lowest measurement bias for transient Cited by: 2.

Scott Huxtable, Co-chairmen Mechanical Engineering (ABSTRACT) Heat flux gages are important in applications where measurement of the transfer of energy is more important than measurement of the temperature itself.

There is a need. Temperature limitations are determined by the gage material properties, the method of mounting the sensing element, and how the lead wires are attached. The range of heat flux that can be measured and the time response are limited by the gage design and construction details.

Measurements of a fraction of 1 kW/m 2 to above 10 MW/m 2 are easily obtained with current gages. Experimental Performance of a Micromachined Heat Flux Sensor Paperback – January 1, by S.
