A New Design and Application of Digitial Inductive Sensor

摘要:

传统电感测量中由于检测装置结构复杂、采用模拟接口,抗干扰能力差,精度不高等,针对这些缺点,设计了一种低功耗的电感感测装置,采用TI最新推出世界首款电感到数字转换器LDC1000做为探头,通过SPI接口与MSP430G2553实现高速数据采集,使得装置功耗降低,体积减小,数据处理方便快捷;实验证明:该装置能够在恶劣的环境中大大提高可靠性,实现高灵敏度、高速数据处理且运算量小,可应用在灰尘、污垢、油和潮湿等恶劣环境中。

Abstract:

Traditional inductive measure method have limited in application,such as inconvenience installation、complicated structure、poor performance of anti-interference、 analogy interface、lower accurate etc. In order to resolve this problem,A detection device is introduced,which based on ultra-low-power MSP430,a probe is designed by Texas Instruments recently present LDC1000 which is the world’s first inductance-to-digital converter,use an SPI interface connection to an MSP430G2553 in order to implement high-speed data transmission,these make the device low power dissipation,volume decrease,facilitating high-speed data processing. The test results show that the device can greatly improve the reliablility in harsh environment,high reliable data collecting ,high-speed data transmission and little computation,high sensitivity,can be used in the presence of dust,dirt,oil,and moisture.
