Specialty protection modules provide monitoring solutions for speed, overspeed, acceleration, reverse rotation, locked rotor, thrust, case expansion, differential expansion, common process measurements and differential measurements, and temperature and differential temperature. These solutions are typically applied in the monitoring of steam and hydro turbines, aeroderivative and industrial gas turbines, turbo-expanders, large pumps, and compressors. All specialty protection modules communicate via DeviceNet™ network.
Our dual speed modules measure speed, rotor acceleration, and peak speed. They can also detect zero speed, locked rotor, and reverse rotation. In addition, these modules are components of Electronic Overspeed Detection Systems (EODS).
Our position modules provide static turbine supervisory position measurements, including axial position (thrust), valve position, differential expansion, and case expansion.
Our process modules measure DC voltage or loop current and report and alarm on the data value, the rate of change for each channel, and the difference between adjacent channels.
Our relay modules provide additional relay capabilities to our XM® series of intelligent I/O modules.
Our temperature modules measure either Resistance Temperature Detectors (RTDs) or grounded or isolated thermocouples. These modules report and/or alarm on the measured temperature, the rate of change for each channel, and the difference between adjacent channels.
