Moorestown, NJ. H.G. Schaevitz LLC, dba Alliance Sensors Group (ASG), announced the release of its LA-27-A Series LVDT linear position sensors, designed to handle the environment found around power-generation turbines. Available in ranges from 3” (75 mm) to 15” (375 mm), the LA-27-A is suitable for valve position feedback in steam and hydro power plants as well as for use in heavy-duty applications like factory automation, civil engineering, and fluid power systems. It can operate in hostile factory environments such as lubricant and chemical mists plus airborne grit and dust, and it can survive industrial wash downs. It works with the company’s Model S1A DIN-rail-mountable LVDT signal conditioner.
LA-27- A features:
- Stock ranges from 3” to 15” (75 mm to 375 mm)
- Core enclosed in 3/8” (9.5 mm) diameter extension rod with 5/16-24 or 8-mm male threaded end
- 050” (26.7 mm) diameter heavy wall aluminum housing (stainless steel available)
- Two double-contact shaft seals keep out contaminants
- Heavy duty connector or cable termination
- Continuous operation to 250°F (120°C)
- Environmentally sealed to IEC IP-68
Options:
- Stainless-steel housing
- External auxiliary shaft seals
- Mild radiation resistant version for nuclear power plants (30 Mrads for 40 years)
- Mounting hardware including flanges, single hole mounting kits, swivel rod eye ends, ball joints, extension rods, hold-down clamps, and tie bars for dual-mounted LVDTs
- Radial connector or radial cable versions available as LA-27-R Series
The company said the LA-27- A Series can replace LVRTs and LVDTs used on steam-control and transfer valves, adding that the core of an LA-27- A is totally enclosed in an extension rod assembly from which it won’t break loose, while offering a sturdy male thread for easy mechanical connection. An LA-27- A Series LVDT can be installed with ASG-provided mounting clamps that can be fastened using the same holes as utilized for steam-turbine LVRTs.
