(NewTek: Pennsauken, NJ) -- NewTek manufactures custom linear position sensing units in various strokes, sizes, and materials engineered to operate reliably in hostile environments where temperatures can reach up to 200 °C.

Unlike magnetostrictive position sensors and other electronic sensing technologies, which depend on integrated electronics that can degrade or fail under prolonged heat, NewTek AC-operated LVDTs contain no internal microelectronics at the sensing element. This design reduces thermal drift, eliminates the need for extensive shielding and cooling, provides superior survivability under sustained high temperatures, and allows simplified mechanical installation.

NewTek NTC LVDT Signal Conditioners power and process signals from these AC-LVDTs that operate directly in the hot zone. The external signal conditioner demodulates the low-amplitude AC output and converts it into DC voltage, current, or digital output for meters, PLCs, and other control systems. By keeping sensitive electronics away from the heat, the system ensures long-term reliability and performance.

Customization that fits specific needs

NewTek offers custom configurations of its high-temperature position sensors with custom mounting configurations, compact housings, multiple stroke lengths and sizes, as well as high temperature-resistant materials and construction. Each unit is engineered to meet the exact environment, mechanical, and performance requirements of a project.
