摘　　要：现代自动化设备中传感器越来越多,它们都是可以通过统一的中央电源供电,所有比例电压输出的传感器可以在电源电压波动的时候同步得到修正,每个传感器也不再需要一个基准电压器件。AMG公司的OEM压力传感器AMS5812是一种可产生与压力成比例的模拟和数字输出信号的压力传感器。本文以压力传感器AMS5812为例,详细描述了在压力传感器中比例电压输出的概念和用途,并探讨了比例电压输出的误差问题。There are more and more sensors in modem automation equipment,all of which can be powered by a unified central power supply.All sensors with proportional voltage outputs can be corrected synchronously when the power supply voltage fluctuates,so each sensor no longer needs a special reference voltage device.OEM pressure sensor AMS 5812 from AMG(analog microelectronics GmbH)is a kind of sensor,the analog and digital outputs of which are proportional to the measured pressures.With AMS 5812 as an example,the concept and application of proportional voltage outputs of pressure sensors are described in detail,and the error of proportional voltage output is discussed.
