Original Press Release:

New LA-25-R LVDT Linear Position Sensor by Alliance Sensors Group for Extreme Environments

H. G. Schaevitz LLC, Alliance Sensors Group is proud to release its LA-25-R series LVDT linear position sensors designed to handle the extreme industrial environments found in steam and hydro power plants; paper, steel, and aluminum mills; die and stamping presses; building and bridge monitoring; and industrial automation and fluid power systems. Available in ranges from 3 inches (75 mm) to 15 inches (375 mm) full scale, the LA-25-R is ideal for roller gap positioning, process valve displacement, and head box and actuator position feedback with the durability needed to withstand hostile conditions. Its open bore design works well in factory environments where debris such as lubricant and chemical mists, airborne grit and dust, and typical industrial wash down can flow through the bore. The robust LA-25-R LVDT linear sensor has a sturdy one-inch (25.4 mm) diameter heavy wall housing of aluminum or stainless steel and is offered with a choice of several radial connectors or a cable in a metal cord grip.

For the LA-25-R series LVDTs, ASG offers a variety of mountings, including saddle-type clamps, a two-hole flange that screws onto its front bushing, and single hole mounting through a bulkhead up to 1/8 inch thick. The LA-25-R's core is enclosed in a core extension rod assembly from which it can never break loose, while offering a sturdy male thread for easy mechanical connection. When mated with ASG's SC-100 industrial LVDT DIN-rail-mountable signal conditioner, an LA-25-R LVDT becomes an ideal solution for heavy duty industrial applications for position sensing.
