The Models 5D30 and 5D30V are high-reliability conditioners for measurement of displacement, force, pressure, and other parameters obtained with a linear variable differential transformer (LVDT) or other variable transformer transducer.

The 5D30 delivers filtered analog output of +/-5 VDC, while the 5D30V produces +/-10 VDC. Based on the synchronous carrier-demodulator principle, both models can handle a remarkably wide range of signals (from 16 to 4000 mV/V/inch, full scale)—with no special "long-stroke" cabling required for high-output sensors. Three selectable operating frequencies are provided to best match the user’s specific transducer. Exceptional signal stability and accuracy over the entire input range are achieved through

• regulated, remotely sensed AC excitation
• precise linearity / symmetry correction and signal phase adjustment via software commands
• high-stability amplification
• configurable low-pass active filtering
• "absolute" and "two-point" software calibration
• effective signal isolation & ESD protection
