Macro Sensors, a sensor company specializing in the manufacture of LVDT-based linear position sensors and gaging probes, is an approved vendor for LVDT (Linear Variable Differential Transducers) position sensors used on Westinghouse steam turbines; and also for LVRT (Linear Variable Reluctance Transformer) position sensors used on General Electrics' 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.
In addition to offering exact replacement LVDTs and LVRTs that are form, fit, function equivalents with the same electrical and mechanical specifications as Westinghouse and GE stock units, Macro Sensors manufactures exact replacement Power Generation LVDTs that match other manufacturer designs, but at greater cost savings and availability.
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; and double-shielded and epoxy encapsulated ac-operated LVDTs that withstand high shock and vibration levels.
