Reliable in demanding environments
Designed for linear position applications involving heat, pressure, corrosion, radiation, or magnetic interference.
Linear Variable Resonance Technology
A new way to measure linear position where conventional sensors struggle.
LVR — Linear Variable Resonance — technology is designed for applications where temperature, noise, magnetic fields, radiation, corrosion, pressure, or remote electronics requirements can limit traditional analog sensors.
Why LVR Gets Attention
Reliable position feedback becomes harder when the environment gets extreme.
In difficult environments, the challenge is not just measuring position — it is doing so reliably. LVR is designed to help address common linear sensing problems such as signal instability, environmental exposure, and the need to keep electronics away from the sensing zone.
Supports remote electronics
The sensing element can operate in the harsh zone while electronics remain in a protected location.
A different sensing approach
LVR uses a frequency-based measurement method that can help reduce sensitivity to analog signal limitations.
LVR is well suited for hot environments such as those found in industrial kilns, where electronics may need to be isolated from the sensing zone.
Application-Driven Design
Built for applications where the environment drives the sensor choice.
Some linear position applications are limited less by the measurement range and more by the surrounding conditions. LVR is intended for cases where harsh operating environments make sensor selection especially challenging.
The goal is practical: make reliable non-contact linear position sensing possible in places where heat, radiation, pressure, corrosion, or magnetic-field exposure complicate the use of conventional approaches.
