摘要：本文介绍了压阻式传感器具有非线性误差，温度过高。此错误可以通过使用传输传感器信息的格言传感器信号调理器和发射器内传感器的固有的重复性局限性的1%降至。一种传输方法调节成比例的输出使用脉宽调制（PWM）。像电流环的对应，PWM输出有良好抗扰度，适合于传输距离越长。MAX1452传感器信号调理器被特色。Maxim>AppNotes>AmplifierandComparatorCircuitsAutomotiveSensorsKeywords:siliconpiezoresistivesensors,PRTs,pressure-sensingapplications,WheatstoneBridge,sensor-signalconditioners,ratiometricJan24,2003output,current-loopoutputAPPLICATIONNOTE1860PWMOutputsEnhanceSensorSignalConditionersAbstract:Thisapplicationnoteexplainsthatpiezoresistivesensorshavenonlinearerrorovertemperature.Thiserrorcanbereducedtowithin1%ofthesensor'sinherentrepeatabilitylimitationsbyusingaMaximsensorsignalconditionerandtransmittertotransmitsensorinformation.Onetransmissionmethodmodulatestheratiometricoutputusingpulse-widthmodulation(PWM).Likeitscurrent-loopcounterpart,thePWMoutputhasgoodnoiseimmunityandissuitabl……
