| Summary: | The article discusses the issues of improving strainresistive pressure sensors (PS) for their joint use
with modern achievements of fiber optics (FO). The
possibilities of implementation and features of FO pyrometric compensation of the temperature error
of semiconductor and resistive strain-resistor, optical
and/or electrical heating of the strain gage for selfcalibration of the pyrometer, power supply by optical
radiation transmitted through a light guide with
galvanic isolation of the PS circuit, increased noise
reduction and fire and explosion safety are considered.
Noise properties of semiconductor and resistive strainresistor are also considered. |
