The Demod-DVRT-2 signal conditioner provides complete conditioning for all LORD MicroStrain displacement variable reluctance transducer (DVRT®) sensors. It offers exceptional resolution and linearity in a small, convenient module.
With a signal-to-noise ratio of 7600-to-1, the Demod-DVRT-2 conditioner improves on the technology previously offered in LORD MicroStrain’s original model. The Demod-DVRT-2 conditioner has a drift-over-time measure of 9 μV/hr, and with an operating temperature of -20° to 60° C, it is designed for applications where conditions previously prohibited use. Ideal applications include condition/deformation monitoring, assembly verification, precise feedback for motion control, and strain/deflection measuring.
“We are very pleased to unveil the Demod-DVRT-2 signal conditioner,” said Thomas Leamon, Engineering Manager for LORD MicroStrain’s displacement division. “We believe it is an essential technology for people who rely on displacement sensors in their work and research. With up to ten times improved resolution, it provides highly-accurate, repeatable measurement in a wide variety of situations. And after a simple re-calibration, our existing customers will be able to easily use the Demod-DVRT-2 signal conditioner with their current sensors for better performance.”
Each system consists of a sensor, cable, and signal conditioning module that are 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. An additional backplane accessory allows stacking of up to four Demod-DVRT-2 modules for increased channel capabilities.
