MADE IN THE USA


The HGSI GH-750-A series AC Spring Loaded Linear Variable Differential Transformer (LVDT) Position Sensors are used to monitor
and track the linear motion or position of a target. These spring-loaded ruggedized sensors are ideal for use in industrial and laboratory
applications including automotive R&D, motorsports, industrial, motion control, medical, military and aerospace.

The sensor shaft is spring loaded and guided by a pair of precision sleeve bearings. These hermetically sealed sensors are constructed
entirely of stainless steel and are resistant to dust, water, temperature, shock, and vibration. For the air-extend option, the shaft is
extended by introduction of a low pressure (10-30 psi), clean, dry air supply, with a regulated flow, through a 1/4 barbed fitting on the
end of the unit. With the release of pressure, an internal spring returns the probe to its fully retracted position.

The GH-750-A series will operate with most any conventional differential input AC LVDT signal conditioner, but operation with
ratiometric signal conditioning is not recommended. HGSI offers a full line of compatible AC LVDT signal conditioners.
