The Model 1003 Transducer Indicator provides complete electronic support to AC and DC LVDT’s, or other DC powered transducers. The AC version provides an appropriate excitation voltage (at 3 or 7 KHz) for the LVDT and also demodulates the output, providing not only a digital readout, but a continuous analog output. This eliminates the need for a separate oscillator/ demodulator. The DC version contains a dual power supply for transducers requiring both positive and negative excitation. Ideal for use in the lab or in a high speed closed loop system, this versatile indicator comes standard with a 5 digit L.E.D. readout to provide maximum resolution.
