ASG Releases GHS-19 Series LVIT Gaging Sensors

Alliance Sensors Group recently introduced its GHS-19 series of spring-loaded linear variable inductive transducer (LVIT) gaging sensors.

The contactless devices were designed for dimensional gaging and position measurements in factory automation and industrial and commercial applications where the sensing element cannot be attached to the object being measured. Using LVIT technology with its simple coil design, the GHS-19 series promises excellent stroke-to-length ratios resulting in much shorter housings.

The GHS-19 serves as a low-cost drop-in replacement for spring-loaded LVDTs, with the same connector and pinouts. It offers a 19-mm (0.75-inch) diameter aluminum or stainless-steel body with a 1/2-20 UNF-2A threaded nose 38 mm (1.5 inches) long and two 19 mm (0.75 inch) hex jam nuts for drop-in installation in place of spring-loaded DC-LVDT gage heads.

The sensors’ 0.25 dia. probes are equipped with a No. 9 contact tip, producing a maximum tip force of 0.45 kgf (1 pound). They are offered with a PT02A-10-6P. Operating from a variety of DC voltages, the sensors are available with a choice of four analog outputs, and they all include ASG’s proprietary SenSet field calibration feature. Available in full scale ranges from 13 to 100 mm (0.25 to 4.0 inches), the series’ contactless operation prevents sensor wearout from dithering or rapid cycling.
