针对有线液位测量技术中电磁干扰和布线不便等局限性,提出了一种无线液位测量装置的方案.该方案主要由直流电极液位传感器、单片机和无线收发模块组成.MSP430系列单片机是主控芯片.采用nRF905无线收发芯片组成无线传输系统.试验结果表明:该装置实现了液位点式测量和无线传输,可满足工业现场的要求.%To the limitations of electromagnetic interference and wiring inconvenience in the wire liquid level measuring technology , this paper pul forward and researched the project of wireless liquid level measuring device. This project was chiefly composed of the direct current electrode liquid level sensor, microcontroller and wireless transceiver module. MSP430 MCU was the main control chip. The experinmetal results show that the device has realized the accurate liquid level measuring of the conductive liquid in the type of point and wireless transmitting,and it can be used to the industrial field.
