LVDT Position Sensors Relish Harsh Environments With Limited Space

NewTek Sensor Solutions introduces a miniaturized series of ac-powered position sensors with a 3/8-in. diameter that provides reliable linear position feedback in rugged industrial applications with tight space and weight restrictions. Resistant to harsh and high-pressure environments, the M-375 Series LVDTs provide high response dynamic measurement for machine operations such as robotics, automatic inspection equipment, plastic injection molding, hydraulic cylinder and valve positioning, downhole drilling, and dimensional gaging. They also suit medical devices. 


With a corrosion-resistant, nickel-iron alloy housing and core, the environmentally-robust sensors operate in temperature extremes of -65°F to +275°F (-55°C to +°135C), with optionally extended ranges of   -65°F to 400°F (55°C to 204°C).   A vented design exposing the interior coil assembly equalizes pressure inside and outside the LVDT, enabling greater endurance to high pressure and temperature as well as shock and vibration.

The LVDTs are available in measurement ranges from ± 0.025 to ± 1 inch and provide linearity of < ± 0.25% over the full range with feature excellent repeatability of <0.01% of full range.  Cost-effective replacements to magnetostrictive sensors, these miniature position sensors are interchangeable with most manufacturer units and can serve as drop-in replacements.  For more details and specs, view the M-375 Series datasheet and visit NewTek Sensor Solutions.
