Macro Sensors - PRODUCT NEWS

General Electric qualifies Macro Sensors to supply 
LVRT Position Sensors for Steam Turbines.
Macro Sensors, an American Sensor Technologies (AST)
company specializing in the manufacture of LVDT-based
linear and rotary sensors, gaging probes, support electronics
and related instrumentation, has been named a GE SQE-
(Supplier Quality Engineering) approved vendor for LVRT
(Linear Variable Reluctance Transformer) position sensors
used on General Electric’s steam turbines.

The LVRTs are implemented for position measurement on
governor valves, throttle valves, reheat/stop valves, interceptor
valves, and many other control valves. 
Macro Sensors offers a variety of its three-wire LVRT-type linear
position sensors to General Electric for turbine valve monitoring
and control in electric power generation plants.  Units are available
in a variety of configurations and outputs to fit different applications.

For example, Macro Sensors’ VRT-750 series of 3/4-inch diameter
hermetically sealed LVRTs are used by some systems integrators
rebuilders to replace OEM GE-style LVRTs.  All popular units are
available from stock, with attractive pricing for electric power utilities
and turbine control systems integrators.  
Macro Sensors also offers a cross-reference guide for exact G.E.
and OEM replacement LVDTs and LVRTs that work with existing
OEM control systems and updated retrofitted controls. For more
