The LHA-19-A series AC-LVDT (Linear Variable Differential Transformer) linear position sensors by H.G. Schaevitz LLC dba Alliance Sensors Group are hermetically sealed, contactless devices designed for industrial and commercial applications, such as: factory automation, metal and paper mills, valve position, robotic assembly systems, pharmaceutical and food processing, and outdoor wet environment applications. These ruggedized linear devices have excellent price-vs-performance and stroke-to-length ratios, making the LHA-19-A AC-LVDT sensors ideal for use in power generation and industrial automation equipment, and many OEM positioning applications.
LHA-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. LHA-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 SS housing and are offered with either an imperial or metric threaded 0.188 inch (4.8 mm) diameter core, PTO2-10-6P (6-pin) connector, and have a 0.235 inch (6.0 mm) ID for good core-to-bore clearance. They feature a wide operating temperature range.
When mated with ASG’s industrial AC-LVDT DIN-rail-mountable signal conditioner, the LHA-19-A series AC-LVDT becomes part of a complete measurement solution. ASG's AC-LVDTs are also offered in other diameters and longer range versions, including the LA-9.5, LA-19, LA-20.6, LA-21, LA-25, and LA-27.
