Development of high accuracy temperature transmitter
Luo Jian Wen · Journal of Transducer Technology · 2003
The high accuracy temperature transmitter is designed with Pt100 as example.In designing, nonlinearity of platinum resistance is considered,and influence of reference voltage waviness and interference to temperature measurement in industrial locale is also taken into account.The concept of temperature sensitivity coefficient is defined,and made as the important designing specification. Its application shows the transmitter features high measuring accuracy and high antiinterference.
