TSI system can continuously monitor the steam turbines of all important parameters, such as: to speed, over-speed protection, eccentric, shaft vibration, cover vibration, axial displacement, differential expansion, and thermal expansion of the parameter monitoring, so that the machine maintenance more planning and improve the availability of steam turbine unit. The TSI system mainly consists of sensors and intelligent components. Sensor is a mechanical and electrical conversion device that converts mechanical vibration quantity, displacement and rotational speed to electric quantity. According to the performance of the sensor and the requirement of the test object, the rotating speed, eccentricity, shaft displacement, shaft vibration and differential expansion of the steam turbine unit are measured by eddy current sensor.
The following instruments and meters are researched and developed by DEC, dedicated to this system, are more accurate, convenient for debugging and maintenance, and excellent in linearity.
