Alliance Sensors Group announces the new LA-25 series LVDTs for use in steel, aluminum, and paper mills as well as in fluid power systems and hydro plants.
The LA-25 is robust and designed to survive heavy-duty applications in harsh environments. Typical LVDTs offered to the heavy industrial marketplace are 0.75 inches in diameter with lead wires. This robust linear position sensor has a 1.00-inch OD aluminum housing (stainless steel housings are available) with a wall nearly 5 times as thick as typical LVDTs, and terminated with either a cable in a cord grip or heavy-duty axial connector. The durability of its housing protects an LA-25 sensor from damage when stepped on or having material dropped on it. The LVDT’s housing has a threaded end nose that can go through a 0.88 hole in a bulkhead or bracket up to 0.13 thick, permitting single hole mounting using an optional mounting kit containing a hex nut and lock washer.
Other LVDTs are offered with a 0.188 inch OD core that is not usually captive to the LVDT body and can easily be lost, damaged, or broken loose from its mating rod. An LA-25 LVDT’s core is enclosed inside a 0.375 diameter stainless steel connecting rod assembly from which it can never break loose, and which moves within a bronze bushing equipped with two double contact shaft seals to keep out dust, dirt, and fluids. The rod has a 5/16-24 UNF male-threaded end for connection of the user’s work piece or optional end pieces available from Alliance Sensors. A radially terminated version with rod ends attached to the core rod and the back end of the sensor is also available.
Available in full ranges from 3 inches to 15 inches, an LA-25 is ideal for roller gap measurement, head box feedback, control valve shaft position, and hydraulic actuator position feedback. It has the ruggedness to withstand the harsh environments in steam power plants; paper, steel and aluminum mills; fluid power systems; and hydroelectric plants. Rated IP-67, the LVDTs can survive the usual industrial wash downs and equipment cleaning. When mated with an Alliance Sensors model SC-100 LVDT DIN-rail mountable industrial signal conditioner with push button calibration, an LA-25 LVDT becomes part of an optimum solution for practically any heavy industrial position measuring applications.
