Characteristics and calibration of "ratiometric output signal" sensors

＂Ratiometric output signa＂ is a kind of non-standard signal,which has been used in equipments imported from overseas increasingly and widely. In order to solve the problems on the calibration of this new kind of signal,calibration and data processing methods of ratiometric output signal sensors were proposed,according to signal characteristics and the national standards for sensor calibration. In depth analyses of calibration equipment,the selection of standard instrument and calibration point,the processes and procedures of validation, and data processing methods were performed. After repeated tests and evaluation by actual calibration, the results show that the calibration and data processing methods are practical and feasible. It can help engineers and others who may be interested to better understand the theory and calibration of such sensors.
