[摘要]：This research paper deals with the theory, design, fabrication and test results of a new system which can be used for the remote measurement of temperature rise of hot bodies. Due to the isolation provided by optical fiber, it can also be used in the measurement of temperature of high-potential bodies. The proposed circuit has the capability of providing linear and precise measurement of temperature rise by suitable design of different components. Its main application will be in the remote measurement of temperature rise under hazardous conditions. Experimentally, it has been verified that the relationship between output signal and temperature rise is appreciably linear. (c) 2007 Elsevier B.V. All rights reserved. |
