  • Wireless technology and a rechargeable battery make the DVRT-Link®-LXRS® ideal for remote, long-term monitoring of micro-miniature displacement measurements.
  • User-programmable sample rates up to 4096 Hz
  • Simultaneously transmit real-time data and log to memory
Datasheet Software

Designed for ease of use and general versatility, this printed circuit card provides complete temperature compensated conditioning for any sensors. The DEMOD-DVRT® -TC utilizes both alternating current and direct current excitation of the sensor’s inductive bridge to accurately measure position in the face of temperature gradients. Each card contains the requisite components to facilitate plug-and-play use, including active, jumper selectable low pass filters, input supply line filters with reverse input protection, and output line buffers. The DEMOD-DVRT® -TC sine wave excitation and synchronous demodulator provide excellent noise rejection and elimination of thermally induced potentials.

Datasheet

The DEMOD-DC in-line signal conditioner makes LVDT sensors as easy to use as a potentiometer. With integral signal conditioning electronics, simply connect power, ground, and analog out, and the DEMOD-DC outputs a buffered, high-frequency response voltage proportional to linear position. During the manufacturing process the analog output voltage is digitally trimmed, ensuring every LVDT’s offset and gain values produce optimal system output accuracy. The DEMOD-DC provides internal power regulation and reverse polarity protection and operates with a wide range of input voltages.
