Proofreading equipped sensor signal conditioner

摘要

(57) Abstract This system 1st smallest sensor input value and includes the sensor which senses 2nd maximum sensor input value. The sensor is easy to receive offset error and profit error. This system furthermore, the 1st output signal and has the microprocessor and the aforementioned sensor and is connected between the aforementioned microprocessors the signal conditioner which possess the 2nd output signal. Signal conditioner has the circuit which minimizes the offset error of the sensor and the circuit where profit error of the sensor is minimized. The offset minimization circuit, responding to the aforementioned 1st microprocessor signal, when sensor input value is the smallest sensor value, includes the circuit which forms the signal which substantially is equal to zero. Profit error minimization expedient, responding to the aforementioned 2nd microprocessor signal, when sensor input value is maximum sensor value, includes the circuit which forms the signal which is equal to maximum signal conditioner value substantially.
