LVDT Position Sensor Heavy Duty LA-25 Series
The Alliance Sensors Group LA-25 Series LVDT linear position sensors are designed to handle extreme industrial environments. This robust linear sensor has a sturdy one-inch (25.4 mm) diameter aluminum housing (also available in stainless steel), two double contact shaft seals to keep fluids and solid contaminants out of its bore, and is offered standard with an axial Euro-style connector or cable, and also can be obtained in a through-bore version with a radial connector or cable outlet.An LA-25 LVDT can be utilized where a user might not have previously considered an ordinary LVDT. Available in full scale measurement ranges from 3 inches (75 mm) to 15 inches (375 mm), the LA-25 is ideal for roller gap positioning, head box feedback, process valve displacement, and actuator position feedback with the ruggedness to withstand the harsh environments found in steam and hydro power plants; paper, steel, and aluminum mills; and industrial automation and fluid power systems. Sealed to IP-67, the LVDT can operate in hostile factory environments that include lubricant mist, cutting oil spray, and airborne grit and dust, as well as surviving ordinary steam cleaning and wash down. The unit is rated for continous operation at 250 °F (125 C) (higher temperature versions are available), and should the application require it, the LA-25 can be offered in a mild radiation resistant version. The LA-25 line permits a variety of mountings, including standard saddle-type tubing clamps, a two-hole flange that screws onto the front bushing of the LA-25 housing, and a single hole mount through a bulkhead up to 1/8 inch thick with a lock washer and hex jam nut threaded onto the same bushing. The LA-25’s core is enclosed inside of the core extension rod assembly and can never break loose. The connecting rod has a sturdy 5/16-24 UNF (or M8x1.25) male thread for easy mechanical connection. When mated with the Alliance Sensors’ SC-100 industrial LVDT DIN-rail-mountable signal conditioner with push button calibration, the LA-25 LVDT becomes the ideal solution for heavy duty industrial applications involving position sensing. Optional core extension rod fittings The LA-25 and LA-27 can be mounted where one would have never considered using an LVDT previously. The unit is rated for 350degF with a 400degF option available. The strength of the housing protects the sensor from being stepped on or having material dropped on it. This lowers cost of ownership and down time from damaged sensors. When mated with the Alliance Sensors SC-100 industrial LVDT Din rail mountable signal conditioner with push- button calibration, the LA-25 or LA-27 LVDT becomes the ideal solution for heavy duty industrial applications. Besides the LA-25 and LA-27 LVDT, Alliance Sensor Group also offers a line of heavy duty LVDTs for power plants, industrial manufacturing, and process control applications as well as supporting signal conditioning electronics.
