The LA-19-A series AC-LVDT (Linear Variable Differential Transformer) position sensors by H.G. Schaevitz LLC dba Alliance Sensors Group are contactless devices designed for industrial and commercial applications, such as: factory automation, metal and paper mills, valve position, robotic assembly systems, and engine throttle position feedback. These general purpose linear position sensing devices have excellent price-to-performance and stroke-to-length ratios, making the LA-19-A AC-LVDT sensors ideal for use in test and measurement laboratories, industrial automation equipment, and many OEM positioning sensing applications.
LA-19-A series AC-LVDTs are offered in 11 ranges from ±.050 to ±10.0 inches (±1.27 to ±254.0 mm) with excellent linearity and infinite resolution. LA-19-A series AC-LVDTs operate from a nominal 3 Vrms, 2.5 to 3.3 kHz excitation source. They are packaged in a 0.750 inch (19.0 mm) OD stainless steel housing, come with either a unified or metric threaded 0.25 inch (6.35 mm) diameter core, have a 0.313 inch (8.0 mm) ID bore for good core-to-bore clearance, feature 12 inch (300 mm) long lead wires, and operate over a wide temperature range.
When mated with ASG’s industrial AC-LVDT DIN-Rail-Mountable Signal Conditioner, a LA-19-A series AC-LVDT becomes part of a complete measurement solution.
ASG's AC-LVDTs are also offered in larger body and longer range versions, including the LA-9.5, LHA-19, LA-21, LA-25, and LA-27.
