H. G. Schaevitz LLC, Alliance Sensors has just released its GHS-19 series of spring-loaded LVIT (Linear Variable Inductive Transducer) gaging sensors. As contactless devices, they are meant for both dimensional gaging and position measurements, be it in factory automation or in other various industrial and commercial applications. That is, for instance, automotive testing, mil/aero test stands, robotic arms, and packaging equipment, where the sensing element cannot be attached to the object being measured. Thanks to the simple coil design of the LVIT technology, the GHS-19 series offer top-of-the-range stroke-to-length ratios.
Taking a closer look:
GHS-19 sensors have a 0.75 inch (19 mm) diameter aluminum or stainless steel body with a 1/2-20 UNF-2A threaded nose 1.5 inches (38 mm) long and two 0.75 inch (19 mm) hex jam nuts for drop-in installation in place of spring-loaded DC-LVDT gage heads. The sensors’ 0.25 dia. probes are fitted with a No. 9 contact tip, producing a maximum tip force of 1 pound (0.45 kgf). They also come with a PT02A-10-6P. Operating from a variety of DC voltages, up to four analog outputs are available for it which they include ASG’s proprietary SenSet™ field calibration feature.
Summary of the GHS-19 Features:
• Low cost drop-in replacement for spring-loaded LVDTs, with same connector and pinouts
• 0.75 inch (19 mm) diameter aluminum or stainless steel body with1/2-20 mounting thread
• EXCELLENT stroke-to-length ratio means much shorter housings
• Full scale ranges from 0.25 to 4.0 inches (13 to 100 mm)
• 1 pound (0.45 kgf) maximum tip force
• Contactless operation prevents sensor wearout from dithering or rapid cycling
