The DEMOD-DVRT2 is a high-performance, high-resolution, expandable DVRT signal conditioner designed for use with all LORD MicroStrain Displacement Variable Reluctance Transducer (DVRT’s).
Product Highlights
- Accurate, repeatable signal processing for all contact-types
- Modular form-factor for stand-alone single sensor use or use in a four-channel backplane with optional DIN-rail mount
- Filtered and buffered output provides clean, high-level signals to coaxial connections
High Performance
- Precision synchronous demodulation
- Differential amplifier raises AC voltages and provides optimum demodulator performance
- Paired and calibrated with each DVRT sensor for high accuracy outputs
- Line voltage transient filtering and constant current excitation source to the sensor bridge
Easy to Use
- Factory-adjustable output filtering and calibration-model options to match application needs
- Rapid warm-up time
- Analog backplane available for connection optimization
Cost Effective
- Complete position-sensing solution with no integration to other systems required
- Volume discounts
