Bestech Introduces LA-25-A Series LVDT Linear Position Sensors

LA-25-A series Linear Variable Displacement Transformer (LVDT) sensors from Bestech Australia are ranging from 75 mm to 375 mm anddesigned to handle extreme industrial environments.

The LA-25-A is ideal for roller gap positioning, process valve displacement, head box and actuator position feedback with the durability to withstand the harsh 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. It can operate in hostile factory environments such as lubricant and chemical mists, airborne grit and dust, and typical industrial wash downs.


The LA-25-A LVDT linear sensor features a sturdy 25.4 mm diameter heavy wall housing of aluminum or stainless steel, two double-contact shaft seals that keep fluids and solid contaminants out of its bore, and offers a choice of axial connectors or a cable in a metal cord grip.

The LA-25-A series is robust and permits a variety of mountings, including standard saddle-type clamps, a two-hole flange that screws onto its front bushing. The LA-25-A's core can never break loose as it is enclosed in a core extension rod assembly, and offering a sturdy male thread for easy mechanical connection. When integrated withSC-100 industrial LVDT DIN-rail-mountable signal conditioner, an LA-25-A LVDT supplied by Bestech Australia becomes an ideal solution for heavy duty industrial applications for position sensing.
