Vibration Monitoring
Turbine Supervisory Instrumentation, or - TSI, precisely measures, reports and displays the following critical turbine protection parameters to provide you with enhanced supervision to your turbine:
A strong advantage with the TSI family is the flexibility with graphics, trending and alarming within your DCS. Once integrated into the system, graphics can easily be added to existing consoles to display critical vibration information.
TSI accepts and processes signals from a wide variety of transducers, including seismic transducers, eddy current transducers, DC-LVDT transducers and dual probe transducers. Up to two transducers can be connected to a Termination Unit (TU), which receives the inputs from these transducers, conditions the signal and outputs the appropriate data. (The TU contains the power for the transducers; current limited to 20 milliamperes.) Converted from analog signals to digital values using an A/D converter, this data goes to a microprocessor for filtering before being sent to the Multi-Function Processor (MFP) via the expander bus.
