    LORD MicroStrain Differential Variable Reluctance Transducer (DVRT) systems enable precise micro-position measurement for a wide variety of applications. From slow, slight movements over time to high frequency vibration, the DVRT system provides accurate, repeatable measurement. Each system consists of a sensor, cable, and signal conditioning module calibrated as one unit to ensure accuracy is maintained through the entire sensing solution. They are calibrated using a linear fit, multi-segment fit, and a polynomial fit, so interpretation of the measurements can be scaled to best suit the application requirements.

    A wide selection of inductive contact, non-contact, slide, and spring-actuated sensors are available in various stroke lengths. All have a very high linear stroke to body length ratio and fit in spaces where traditional LVDT’s are too large. The sensors are robust and capable of operating in extreme heat and corrosive environments over millions of cycles without degradation in performance.

    LORD MicroStrain offers three versions of signal conditioners including a stackable module for multi-sensor applications; a compact, lower-cost, module; and a temperature-compensated module for sensors with temperature gradients. Available data outputs include analog voltage, serial, and wireless data transmission.
