Physical parameter, e.g. pressure, sensor system with quasi-digital calibration - uses analogue components to calibrate computer which corrects measured parameters

摘要

The sensor system has a measurement head (MP) for determining a physical parameter (P) and can have further heads (MT) for detecting other physical parameters for correction of the initially measured parameter. The measurement signals are digitised by an A/D converter (AD) and fed into a computer (RW) which converts them into calibrated measurement values. The parameters required for the calibration in the computer are set up in discrete analogue components (R1-R12), each of which has a connection to a computer port (P1-P12). USE/ADVANTAGE - For measuring and control of tyre air pressure in land vehicle or aircraft. Enables reliable calibration with minimal electronics.
