THERMAL SENSORS



Indian Space Research Organisation at its Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram has developed thin foil heat flux sensors (Gardon Gauge) and temperature probes. They have applications in a variety of heat measurements like radiative and convective heat flux measurement for short durations in flight, aerodynamic heat transfer measurements on moving bodies during flight, plume heat flux measurement at nozzle exhaust, flame temperature measurement at nozzle exit, hot gas temperature measurement inside combustion chambers etc.

Typical Properties/Characteristics are given in the Annexure.

VSSC is willing to offer the process know-how of processing these sensors to eligible interested parties who are working in the domain of heat transfer/sensors.

Interested entrepreneurs are requested to contact the address given below with all relevant particulars regarding their line of current activity, infrastructure available, market assessment of the product, financial arrangements made, turn over and sales of their products for the past years and a copy of their latest annual report.
