介绍一种采用Nova公司的NPI系列隔离式传感器组件的TZ2 0 0系列扩散硅压力变送器的设计方法 .由于先进的膜片 /充油隔离技术可达到超强的承压能力与介质兼容的能力 ,而一种实用的信号处理电路又可做到大量程的调节 ,这就使该变送器具有宽广的量程和较高的抗腐蚀能力 .同时 ,用来进行温度补偿的电阻环路被制作在混合的陶瓷基片上 ,从而取代作为温度补偿用的外接电路 .通过在电力、化工、石油等领域的应用证明了上述特点 .
A design methodology for the TZ2 0 0 series of diffused silicon pressure transmitters using Nova’s NPI series of isolated sensor components is introduced. Due to advanced diaphragm / oil-filled isolation technology, superior pressure bearing capacity is compatible with the media Capacity, and a practical signal processing circuit can do a large range of adjustment, which makes the transmitter has a wide range and high resistance to corrosion at the same time, used to carry out the temperature compensation of the resistance loop was Made on a mixed ceramic substrate to replace external circuitry for temperature compensation, these features have been demonstrated through applications in the electrical, chemical, petroleum and other fields.
