Abstract

Abstract

En 中文
The paper presents design, development and testing of a resonant proximity DC current sensor to measure current in the range of 0-20 mA. The sensor is built using cantilever structure with piezoelectric excitation, sensing and closed loop electronics. The sensor measures the DC current by measuring the shift in resonance frequency of the cantilever beam. The proposed measurement system is novel, simple and accuracy is found to be 1.1% of full scale deflection. (C) 2011 Elsevier Ltd. All rights reserved.
