The realization of multi-channel fluorescent temperature measuring system

The use of fluorescence technique for temperature measurement has developed since 1980's.Such system has many advantages such as protect against electromagnetic interference, endure high voltage, and non-induce burning or blasting. But at present the high cost of apparatus limited the application widespread. A lot of applications are required and these in turn would depend on the technique improvement and cost reduction. A new kind of multi-channel fluorescent temperature measuring systems (FTMS) has been introduced in this paper. The number of channels can be designed as many as several hundreds. It is very competitive especially in power station and high voltage electrical equipment systems. This technology evidently decrease the average cost of each measurement channel. A sketch scheme and problems that have been resolved in design as well as the result of test is discussed in this paper.
