LVDT Position Sensors

NewTek Pre-calibrated Linear Position Sensors serve as long-term replacements for potentiometers (pots) that become unreliable over time due to their contacting operation and effects from vibration and other environmental parameters. As potentiometers rely on mechanical contact to provide position feedback, components wear out and are affected by heat, vibration, and humidity, making output progressively noisier and unreliable over time. Non-contacting and with no parts to wear out, NewTek LVDT Position Sensors offer frictionless operation and do not drift or get noisy even over extended periods. The excellent repeatability, temperature resistance, and resolution of LVDTs are critical for industrial applications that require measurement of very small movements such as TIR measurements, thermal expansion, and dimension quality.  (see chart and caption) Challenging operating conditions such as high shock and extreme temperatures also can limit a potentiometer’s performance and reliability. As a result, Mean Time Between Failure (MTBF) is typically lower for a potentiometer operating in a moisture-free and low vibration environment, than an AC-operated LVDT Linear Position Sensor working in a demanding application. The high reliability of NewTek LVDT Position Sensors in high vibration and shock environments make them more ideal than pots for use in the position measurement of machine tools, drilling tools for oil and gas, high-temperature steam valves, and other areas.
