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.

The DEMOD-DC® in-line signal conditioner makes DVRT® sensors as easy to use as a potentiometer. With integral signal conditioning electronics, the user connects 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 that every DVRT®’s offset and gain values match one another. The DEMOD-DC® provides internal power regulation and reverse polarity protection, and will operate with a wide range of input voltages.

Ideal for difficult sensing applications, the Non-Contact DVRT® is designed to measure the displacement and proximity of a metal target without physical contact. The measurement is unaffected by interposed nonmetallic, non-conductive materials, such as polymers and biomaterials. The stainless shell of the device houses two coils; one for sensing and the other for temperature compensation. The coils and Teflon® cable are mounted on a stable PEEK substrate. This assembly is potted into the stainless housing using high-grade, vacuum-pumped epoxy and includes integral strain relief. This packaging allows the sensor to be used in applications requiring long-term immersion in water and saline solutions.
