MADE IN THE USA
The HGSI GBT-375-A series spring loaded linear variable differential transformer (LVDT) gauging probes are 3/8 inch diameter pencil-type gauging probes used for ultra-precise dimensional measurement. These spring loaded sensors are ideal for use in industrial and laboratory applications including QC, SPC, metrology, and dimensional gauging.
The sensor shaft is spring loaded and guided by a precision linear ball bearing assembly. The non-rotating probe shaft minimizes radial play and effects of side loading. These sensors are constructed of stainless steel and are resistant to dust, temperature, shock, and vibration.
The GBT-375-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. Please contact us for a recommendation.
