METHOD AND DEVICE FOR ELECTROLYTE DENSITY MEASUREMENT IN LEAD ACCUMULATORS Russian patent published in 2009 - IPC G01N9/24 H01M10/48 

FIELD: physics, measurement.

SUBSTANCE: invention is related to the field of process parameters measurement and control. Method and device may be used for measurement of electrolyte density in lead accumulators in composition of accumulator batteries diagnostics system by means of refractometric determination of function, for instance, of Lorentz-Lorentz, index of electrolyte refraction. Measurement of density consists in measurement of photodetector electric signal, which registers monochromatic flow of radiation reflected at the angle of 45° from flat surface of reference material, which is in permanent contact with accumulator electrolyte, measurement of electrolyte temperature and calculation of electrolyte density according to suggested formulas. Device that realises the method comprises refractometric detector, temperature detector and microcontroller, which calculates battery accumulator electrolyte by measured electric signals of detectors.

EFFECT: increased accuracy and validity of measurements, automation, and also design simplification.
