Macro Sensors Satisfies LVDT Requirements for Current and Legacy Turbine Installations

Pennsauken, NJ, July 6, 2006.. Macro Sensors, (, a sensor company specializing in the manufacture of LVDT-based linear position sensors and gaging probes, offers a broad range of Linear Variable Differential Transducers (LVDTs) linear position sensors in various configurations and outputs to satisfy the requirements of both current and legacy turbine installations.

The Company 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:

o Hermetically sealed AC and DC-operated LVDTs with axial or radial connectors.
o UL/ULC- Listed AC operated LVDTs approved for operation in Class 1, Division 2 and Class Zone 2 hazardous locations
o 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. The Company currently manufactures exact replacement LVDTs that are form, fit, and function equivalents with the same electrical and mechanical specifications as Westinghouse stock units. The LVDTs are implemented for position measurement on governor valves, throttle valves, reheat/stop valves, interceptor valves, and many other control valves.
