摘　　要：基于网络的压力传感器是由压敏电阻传感器、A/D转换器、微处理器、存储器和接口电路构成的,它能实现各传感器之间、传感器与系统之间的数据交换和资源共享。本文介绍PPT系列、PPTR系列网络化智能精密压力传感器的工作原理与典型应用。The pressure sensor based on network is composed of piezoresistive sensor, A/Dconverter, micro-controller, memory, and interface circuit. It can realize the data exchange and source-sharing between every sensor and between the sensor and system. This paper introduces the opera-tion principle and typical application of the PPT and PPTR intelligent precision pressure sensorbased on network.
