LVDT Linear Position Sensors

Alliance Sensors Group LA-27-A series LVDT linear position sensors are designed to handle extreme industrial environments. This robust linear sensor has a thick wall aluminum housing (also available in stainless steel), a core enclosed inside of the core extension rod assembly that cannot break loose, while offering a sturdy male thread for easy mechanical connection, and a pair of double contact shaft seals to keep fluids and solid contaminants out of its bore. The sensor’s electrical termination includes the choice of an axial connector or a cord grip with a cable.
An LA-27-A LVDT is ideal for roller gap positioning, head box feedback, process valve displacement, and actuator position feedback with the durability to withstand the harsh environments found in steam and hydro power plants; paper, steel, and aluminum mills; and industrial automation and fluid power systems. It can operate in such hostile factory environments as lubricant mist, cutting oil spray, and airborne grit or dust, and it survives typical industrial steam cleaning and wash downs. Mated with ASG’s SC-100 industrial LVDT DIN-rail-mountable signal conditioner, the LA-27-A LVDT becomes an ideal solution for heavy duty industrial applications requiring position sensing. For operating an LA-27-A as a steam valve position sensor in a power plant, ASG’s model S1A signal conditioner, which is designed specifically for that application, is recommended.
