摘要
介绍一种以MSP430F147为主控芯片的压力变送器数显仪表系统,详细阐述了系统的硬件设计架构,并重点讨论了其温度补偿方案。该仪表通过220 V交流供电,可实现一键切换测量单位功能,并可对外提供独立的±15 V电源,供压力变送器或其他一次仪表使用。实践证明:该仪表精度高、温度漂移低、稳定性强,可作为高精度电测仪表广泛应用于工业、科研、医疗等众多领域。
This paper introduced a design of a digital display meter for pressure transmitter based on MSP430F147 as well as its detail hardware architecture and significant solution for temperature compensation.This meter adoped 220 V AC power supply,can easily switch the measurement unit by a key and can supply ±15 V power source for pressure transmitter and other primary instruments.With high accuracy,low temperature drift and strong stability,it can be widely used as electrical measuring instrument in industry,scientific research,medical therapy and many other fields.
