Non-Contacting LVDT Position Sensors Address Downhole Drilling Apps

NewTek Sensor Solutions offers standard and custom LVDT Position Sensors that operate with reliability and infinite resolution in the high-pressure and high-temperature environments of downhole drilling applications.   Robust, rugged, and friction-free, the sensors ensure accurate position feedback to avoid costly downtime associated with failing sensors.  They are said to be ideal for use in a variety of downhole applications including cutter orientation to ensure accurate drilling direction, wellbore case profiling for active predictive maintenance, as well as wire and cable line tension measurement.  


Addressing the extreme temperatures and pressures present in drilling environments, the LVDTs are constructed with special materials that ensure reliable operation in temperatures up to 400°F (204°C) and pressures to 20,000 psi (1,380 bar).  Hermetically-sealed LVDTs withstand exposure to a variety of fluids including sulfides, acids, drilling mud, and other corrosive chemicals.  In the most demanding environments, linear position sensors constructed of exotic electrical materials, ceramics and special core materials meet temperature requirements up to 1,000°F (538°C).

New VNA technologies enable mmWave broadband testing to 220 GHz, helping researchers and engineers to overcome test challenges and simplify mmWave testing.

Application development in the mmWave frequencies is growing. Broadband testing over hundreds of GHz of bandwidth is subject to repeatability/accuracy deficits, and engineers demand solutions to help overcome challenges and simplify mmWave testing.


NewTek also offers subminiature LVDT configurations with a 3/8” outer diameter and low-mass core to fit in areas and devices with limited space and vented units that withstand a combination of high pressures, temperatures, shock, and vibration.  For more information, visit NewTek LVDT and contact Mike Marciante at 856-406-6877 to discuss application requirements.
