INTRODUCTION
Heat Flux Sensors of HRX series – the series of high sensitive and self-
calibrating miniature sensors for radiation heat fluxes.

High sensitivity
Miniature design
Self-calibrating
SMD style
A range of customized dimensions
The Sensors are developed as a series of sizes: 4x4 and 6x6 mm
2
. Optional
dimensions (size and thickness) as well as customized performance
parameters are available on request.
The Sensors have wireless package of SMD style, suitable for SMD
mounting by flip-chip method. Connectors of the sensors come out to back
side of the package.
The Sensors were developed for measurement of radiation heat fluxes in a
wide range of heat flux intensities. The high sensitivity of the Sensors of
the series provides accurate experiments and data on objects of
investigations.
One of the feature of the Sensors is the self-calibration method (patent
pending RU2014145948 dated 17.11.2014). It means possibility to
calibrate precisely the Sensor by measurement of its thermoelectric
performance parameters. It is not necessary to remove it and send to labs.
The calibration procedure is possible with use of RMT Datalogger of the
DX8140 series, specially developed for thermoelectric heat flux Sensors, or
by use of RMT Z-meters. The calibration procedure is described in Chapter
10.
