Transducer Indicator

Transducer Indicator

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.

Calibrating the unit is accomplished via membrane switches on
the front panel, eliminating the need for internal trim pot
adjustment. The user can calibrate the unit by simply entering
the full scale endpoints, the zero position, and decimal point
location. This allows a readout in inches, degrees, or other
engineering units corresponding to the application. During the
calibration, there are 6 user defined setpoints: two high, two low,
and the high and low hysteresis points for the system. When the
specified tolerances are exceeded, indicator lights are illuminated,
providing a visual signal to the user. Optional relays, which
correspond to the distinct set points, will add another level of

automation to the user’s process. A tare function, which allows
the meter to be zeroed anywhere along the transducer’s travel, is
standard. This feature can be used to measure the deviation from
a standard within the working range of the sensor.
The Model 1003 features a continuous analog output for use as
an input to a control process or A/D converter. Optional RS232C
Serial output is offered for direct connection to PC based data
acquisition systems, eliminating the need for external signal
conditioning. All connectors necessary for indicator operation
are provided, as well as a complete instruction manual.
