The GHS-19 series of LVIT (Linear Variable Inductive Transducer) spring-loaded position sensors by Alliance Sensors Group are contactless devices designed for dimensional measurements in QA labs, or position measuring applications in factory automation systems, and in various industrial and commercial applications, such as: automotive testing, mil/aero test stands, robotic arms, and packaging equipment. An ideal solution for when the sensing element cannot be attached to the object being measured. GHS-19s are offered in nominal full scale ranges from 0.25 to 4.0 inches (6.4 to 100 mm) with excellent resolution and high stroke-to-length ratios. The maximum tip contact force on the item being measured is 1 pound.
GHS-19 sensors have a 0.75 inch (19 mm) diameter aluminum or stainless steel body with a 1/2-20 UNF-2A thread 1.5 inches (38 mm) long with two 19 mm (0.75 inch) hex jam nuts for drop-in installation in place of a spring-loaded DC-LVDT gage head. These sensors utilize a probe equipped with a No. 9 contact tip, and are offered with a PT02-10-6P (6-pin) connector. Operating from a variety of DC voltages. These sensors are available with a choice of one of four analog outputs. They all include ASG's proprietary Senset™ field recalibration feature.
