FIELD: instrumentation.
SUBSTANCE: invention relates to instrumentation. Proposed transducer comprises objective-lens with fibre waveguide with polished light transmission end, photo receiver fitted in the case with outlet window, thermostat including thermostat coil for photo receiver and protective shell composed by corrugated metal sleeve. Heat insulation sleeve is fitted in between said protective shell and waveguide. Photo receiver is arranged inside the thermostat coil. Waveguide polished end face is arranged with clearance relative to photo receiver inlet window.
EFFECT: higher accuracy of measurements, accelerated switching to steady-state.
