Macro Sensors, a sensor company specializing in the manufacture of LVDT-based linear position sensors and gaging probes, is now an approved vendor for LVDT (Linear Variable Differential Transducers) position sensors used on Westinghouse steam turbines and for LVRT (Linear Variable Reluctance Transformer) position sensors used on GE’s steam turbines. Siemens-Westinghouse and GE implement the LVDTs and LVRTs, respectively, for position measurement on governor valves, throttle valves, reheat/stop valves, interceptor valves, and many other control valves. The units are available in a variety of configurations including: hermetically sealed AC and DC-operated LVDTs with axial or radial connectors; UL/ULC-Listed AC operated LVDTs approved for operation in Class 1, Division 2 and Class Zone 2 hazardous locations; double-shielded and epoxy encapsulated AC-operated LVDTs that withstand high shock and vibration levels. Macro Sensors also provides non-standard and custom-designed units for OEMS and system integrators. An online catalog of Power Generation Position Sensors that work with existing OEM control systems and updated retrofitted controls can be downloaded from Macro Sensors’ website.
