Heavy Duty LVDT Linear Position Sensor Product Lines from Alliance Sensors Group div. of H. G. Schaevitz LLC


Moorestown, New Jersey, April 26, 2021…Alliance Sensors Group div. of H. G. Schaevitz LLC has developed a broad line of LVDTs for power generation and heavy industrial applications. Alliance Sensors Group’s engineers have extensive experience in the LVDT field and have listened to its customers to include features that have often been requested such as encapsulating the core so it cannot break loose from its core connecting rod. ASG LVDTs are used for steam valve position sensing in power plants and for heavy duty operations in steel, aluminum, and paper mills, or on stamping presses, press brakes, and mining machinery, where an ordinary LVDT will not survive.


Standard Features for all ASG Heavy Duty LVDTs:

- Full scale ranges from 3 to 16 inches (75 to 400 mm)

- Core totally enclosed in 3/8 inch (9.5 mm) diameter extension rod with 5/16-24 or M8 male threaded end

- Environmentally sealed to IEC IP-68


PG Series:

- Continuous operation to 350° F (175 C)

- No connector - - sensor has screw clamp terminals for AWG 24-14 wires

- Two double-contact shaft seals keep out contaminants

- Super duty version available with double wall thickness


LA-25 and LA-27 Series:

- 25 and 27 mm diameter heavy wall aluminum or stainless steel housing

- Two double-contact shaft seals keep out contaminants

- Axial cable or connector terminations

- Continuous operation to 220° F (105 C) or to 350° F (175 C) on select models


LA-21 Series:

- 20.5 mm diameter housing

- Axial lead wires for individual connections to each winding

- Continuous operation to 350° F (175 C)



-  External auxiliary shaft seals for extremely severe environments

-  Mild radiation resistant versions for nuclear power plants (10 Mrads for 40 years)

              -  Mounting hardware including flanges, single-hole mounting kits, hold down clamps,

                   ball joint or swivel rod eye ends, extension rods, and tie bars for dual-mounted LVDTs


When mated with either ASG’s S2A LVDT signal conditioner for power generation applications or SC-200 LVDT signal conditioner for standard industrial applications, ASG can provide a complete position measurement solution.
