1原理温度传感器中最常用的传感元件是钻电阻，用户常用ppl00等型号的拍电阻，其线性不好导致测温精度降级。采用BB公司的XTR103变送器可解决这一问题，它通过对钻电阻信号进行电流激励、放大及线性化处理，最终变送为4～20mA电流信号输出。如图所示，温度传感元件为PT100，三?
1 Principle Temperature sensor is the most commonly used sensing element drilling resistance, the user commonly used ppl00 and other models of the resistance, the linearity of the temperature measurement accuracy led to poor degradation. The use of BB’s XTR103 transmitter solves this problem by current-stimulating, amplifying and linearizing the drill resistance signal, eventually delivering a 4-20 mA current signal. As shown, the temperature sensing element PT100, three?
