The Alliance Sensors Group PGSD Series linear sensors are the first LVDT-based valve position sensors designed and engineered specifically for applications in electric power generating steam turbine control systems. Many features of the Alliance Sensors Group PGSD Series Position Sensors were requested by power gen controls engineers and are embodied in the PGSD Series Super Duty LVDT. The PGSD Series Position Sensors are available in full ranges from 3 to 15 inch, (76 to 380 mm).
Electrical connections via Euro-style screw clamp terminal block that takes no. 24 to no. 14 wire…no soldering required
3/4 NPS female conduit port accepts liquid tight connectors, cord grips, or flexible conduit fittings. 1/2 NPS female conduit adapter supplied with unit.
Optional mounting flanges, spherical rod eye ends, hold-down clamps, custom extension rods, and other installation hardware readily available
2-Year warranty … twice as long as the industry standard
For use on: Interceptor Valves, Governor Valves, Throttle Valves, Bypass Valves, Stop Valves
Rated for up to 350°F (175°C) operating temperature
Built-in over-temperature indicator for warranty coverage
3/8 inch diameter core extension rod…twice the diameter of typical LVDTs
Totally enclosed core cannot vibrate loose, break off.
Two double contact shaft seals keep grit and dirt out of the LVDT’s bore
Inline ball joint on core rod takes up minor installation misalignment
