1GENERALDESCRIPTIONANDSPECIFICATIONS
The Model 10A30-2C is for measurement of displacement, force, pressure, and other
parameters obtained with a
variable reluctance transduceror linearvariable dif-
ferential transformer (LVDT)
. Based on the synchronous carrier-demodulatorprin-
ciple, it supplies regulated, remotely sensed AC excitation for two independent
transducer channels—thus allowing direct measurement of
thickness(when the two
inputs are summed) or of
taper(when their difference is calculated). It then demodu-
lates, filters, and amplifies the resulting signals to produce system outputs precisely
proportional to LVDT core displacement. The 10A30-2C automatically adjusts to the
signal phase shift of the transducer in use, thereby insuring optimum sensitivity and
linearity. Special input provisions exist for “long-stroke” LVDT's (full-scale range of ±1
inch or greater).

Transducer Types
: 5- or 7-wire LVDT's capable of 3280-Hz operation and having pri-
mary impedance of 80 ohms or greater (all Daytronic LVDT transducers are suit-
able); 3- or 5-wire variable reluctance transducers
Sensitivity Range: Accommodates full-scale ranges from ±0.010 in. (±0.25 mm) to
±6.0 in. (±15.24 cm), when used with Daytronic or equivalent transducers; for System
10 channel “type” codes assigned to 10A30-2C data channels, see Table 1, below
Standard Input (rms, full-scale): 78, 156, or 312 mV/V
Long-Stroke Input (rms, full-scale): 525 mV/V, 1.05 V/V, or 2.10 V/V
Excitation (per channel): Nominal 3.0 V-AC (rms) at 3280 Hz; 40 mA (rms), maximum
Amplifier (per channel):
Common-Mode Range: ±5 V operating; ±12 V without instrument damage
Common-Mode Rejection Ratio: DC and at 60 Hz: infinite; at 3 kHz: -60 dB
Input Impedance: Differential: 400 kΩ; Common-Mode: 100 kΩ
Offset: Initial: ±3% of full scale; vs. Temperature: ±20 ppm/°C; vs. Time: ±0.01%
f.s./month
Gain Accuracy: ±0.02% of full scale typical, following calibration*
Gain Stability: vs. Temperature: ±50 ppm/°C; vs. Time: ±20 ppm/month
Filter (per channel):3-pole modified Butterworth; 3 dB down at 6 Hz; 60 dB
down at 60 Hz
(cont’d)
*Initial (uncalibrated) inaccuracy may be as great as ±3% of full scale. Maximum error that
could occur upon replacement of a Model 10A30-2C not followed by calibrationis ±6% of full
scale.
