Overview

Model DM Digital Signal Conditioner for ac Powered Displacement Transducer.Model DM, for carrier transducers, is a low-cost bench, panel or rack-mounted instrument which contains a power supply, signal conditioner, amplifier (Bipolar 5 V output) and digitizer. The 4 1/2-digit LED display features bright, easy-to-read 14,2 mm [0.56 in] high characters. The compact 1/8 DIN size case measures 97 mm W x 48 mm H x 132 mm D [3.8 in x 1.9 in x 5.2 in]. Wires easily attach to the rear connector using screw terminals. The Model DM features a 5 kHz drive supply for the transducer, a stable signal amplifier and a novel demodulation technique that produces an enhanced accuracy result.
