(NewTek: Pennsauken, NJ) -- NewTek has designed its 100th custom LVDT position sensor, with a vented body and modified lead lengths to address the operating specifications for a downhole drilling application.

Venting NewTek’s NT-R High Temperature Sensor ensured reliable performance in a downhole drilling tool that operated in a high-shock environment with pressures up to 10,000 psi and temperatures up to 400°F (204°C). With vented holes in the housing, the sensor can equalize pressure inside and outside to operate reliably in temperature extremes of –65°F to +400°F and operating pressures of 30,000 psi.

Most sensors do not often meet application requirements for position measurement right out of the box. But NewTek has the engineering and domestic manufacturing capabilities to customize versions of its standard AC- and DC-operated LVDT position sensors to meet unique operating and configuration specifications.

Customizations may include radiation and submersion resistance, higher temperature exposures, ratiometric output, high stroke-to-length ratios, specific electrical output requirements, ceramic and special core materials, and the use of special alloys such as monel, inconel, hastelloy, and titanium in the construction of the sensor body.
