Abstract
Eddy-current (EC) displacement sensors are used in a device for measuring the shaft vibration of turbines. When only the 1mpedance/voltage (Z/V) converter breaks down, it is necessary to recover as soon as possible. Therefore, identification method type of sensor probe and displacement and development Z/V converter which is suitable for each probe sensor are required. In this paper, we propose method for identifying type of sensor probe and displacement while operating a power plant with and adjusting sensitivity of six types of sensor probes. As a result, identifying type of sensor probe and displacement by measuring oscillation voltage, oscillation frequency and DC resistance of sensor probe is possible. In addition, sensitivity that meets the API standards is possible with present adjustment sensitivity method even if estimation error of displacement.
