Position sensors for hostile environments
NewTek Sensor Solutions
High-temperature LVDT (linear variable differential transformer) position sensors (photo) operate in applications with extreme temperature environments where other position-sensing technologies, such as encoders, magnetostrictive sensors and potentiometers, cannot survive. With standard a.c.-operated LVDTs available with temperature ratings up to 400°F (204°C) and custom linear position sensors available with temperature ratings up to 1,000°F (538°C), the company offers sensors in a range of temperature ranges that offer the highest reliability in challenging applications, such as chemical processes (valve position at petrochemical plants), material testing chambers (specimen position monitoring), power plants (steam valve positioning), downhole oil drilling (cutter orientation, wellbore case profiling and wire and cable line tension measurement) and jet engines (valve positioning near engine cores). — NewTek Sensor Solutions, Pennsauken, N.J.
