RADIATION
/ CONVECTION HEAT FLUX SENSOR (RC-01-ATX)
RC-01-ATX
RADIATION / CONVECTION (RADCON) HEAT FLUX SENSOR
The RC-01-ATX is a heat flux and temperature
sensor for study of radiation, convection and heat transfer in ovens, furnaces,
baking and drying processes. The measurement result is often used as a
characterisation of a “fingerprint” of oven settings, making it possible to
compare or reproduce oven settings.

INTRODUCTION
- RC-01-ATX consists of two heat flux sensors, the
one covered by a gold reflector (only sensitive to convective transfer), the
other by a black absorber (sensitive to radiative as well as convective
transfer). A temperature sensor is integrated below the reflector.
- The sensor can be delivered built into special
heat sinks. Normally this is made of nickel; the most common type is
RC-01-ATX-M.
- In case of RC-01-ATX-M, the sensor is supplied with
an external temperature sensor to determine the surrounding air temperature. By
measuring the heat fluxes, sensor temperature and surrounding air temperature
one is able to determine the local heat transfer coefficients.

SUGGESTED USE

Drying kilns, baking ovens
