(NewTek: Pennsauken, NJ) -- NewTek AC-operated LVDT position sensors often serve as a more reliable, precise, and cost-effective alternative to magnetostrictive linear position sensors in the monitoring and control of valves in power generation and hydroelectrical stations. Because power generation environments can reach temperatures of 250°C (475°F), magnetostrictive technology might fail or become inaccurate over time. While very accurate in benign applications, most magnetostrictive sensors cannot operate over 85°C as electronics must be placed very close to the “wand.”

With electronics separated from the LVDT coils, NewTek’s AC-operated linear position sensors continuously operate in power generation stations without failure at high temperatures. While the LVDT sensor remains in a harsher environment, NewTek’s NTC-6000 LVDT Signal Conditioner (which excites the AC-operated LVDT and provides a variety of output options for use in PLCS and other control systems) operates in a less harmful environment. By using a low operating frequency range (between 2kHz and 4 kHz), the LVDT and signal conditioning are able to be separated by 100 feet or more.
