Table 1. Specifications
Model 3178
Transducers:
4-arm bridges, 90 to 1000 ohms. nominally 0.5 mv/v to 5
mv/v, full scale.
Cables:
4-, 5-, or 7-wire, depending on application; 1000 feet
maximum length.
Bridge Excitation:
Regulated 3.28 kHz ac; nominally 2 vac.
Balance Adjustments:
10-turn coarse and fine; will balance 1.5 mv/v
initial unbalance.
Span Adjustments:
10-turn coarse and fine; 0.5 to 5 mv/volt, full scale.
Analog Outputs:
Two
analog outputs available; 0 to ±5 volts with 50%
overrange, 5 milliamperes maximum. Bandpass is dc to 2 Hz or dc to
400 Hz. Active low-pass filters provide for rolloff of 60 dB per decade
above cutoff frequency. Full-scale slew time is 1.4/f seconds, where f
is the cutoff frequency.
Output Ripple and Noise:
0.15% of full scale (rms) maximum for
400-Hz output; 0.02% of full scale (rms) on 2-Hz output.
Accuracy:
0.05% of full scale.
Dimensions:
1.7 x 4.41 x 8.5 (HWD inches).
Operating Temperature Range:
0 to +130 degrees F.
Power Requirements:
105 to 135 volts ac, 50 to 400 Hz at 5 watts
maximum.
