(NewTek: Pennsauken, NJ) -- Hermetically sealed linear position sensors from NewTek Sensor Solutions tolerate the high temperatures and vibrations of steam turbines to deliver accurate and reliable feedback on the position of governor and throttle valves. Their high measurement accuracy also makes them ideal to monitor turbine shell expansion and bearing vibrations as part of process control systems.

As power plants must operate to specific control algorithms, NewTek’s HAR-Series of AC-operated LVDTs can help operators determine when valves are closed or open, and to what degree. Maintaining these algorithms ensures turbines operate efficiently and cost effectively.

Providing feedback on turbine shell expansion, these sensors give operators the measurements needed to determine the thermal growth of steam turbines as the shell expands during startup, operation, and shutdown. These measurements help identify whether dimensions exceed expected temperature growth differentials. In addition, when installed on various locations on a steam turbine, the HAR-Series hermetically sealed position sensors monitor bearing vibration to detect bearing clearance limits that indicate bearing wear.
