摘　　要：MAX1 4 57是一种专用传感器信号处理器 ,它可以补偿硅压阻式传感器的温度误差和非线性误差 ,使传感器总的重复性精度达到 0 2 %以内。MAX1 4 57对传感器进行温度补偿时需要经过一系列操作步骤和参数的选择计算。本文分析了MAX1 4 57的工作原理和补偿过程 ,在此基础上开发的温度补偿软件 ,可以实现参数的自动计算 ,自动调整 ,补偿的每一个操作步骤均辅以向导式的提示。该系统的使用使得MAX1 4The MAX1457 is a special sensor signal processor optimized for piezoresistive sensor calibration and compensation. Achieving a total error factor within 0 2% of the sensor's repeatability errors, the MAX1457 compensates temperature errors and non-linearity of silicon piezoresistive sensors. The choice and calculation of parameters and a series of steps for compensating temperature errors of sensors are needed for this operation. The principle and compensation process of MAX1457 are discussed in this paper based on which the software of compensating temperature errors is designed. Each step of compensation is guided by accessorial explain and the automatic calculation and automatic adjusting of parameters are realized. The system has simplified the process of sensor compensation greatly.
