Model 10A31-4 Four Channel AC LVDT Conditioner

is for measurement of displacement, force, pressure, and other parameters obtained with a variable reluctance transducer or linear variable differential transformer (LVDT). Based on the synchronous carrier-demodulator principle, it supplies regulated, remotely sensed AC excitation for four independent transducer channels. It then demodulates, filters, and amplifies the resulting signals to produce system outputs precisely proportional to LVDT core displacement. The 10A31-4 automatically adjusts to the signal phase shift of the transducer in use, thereby insuring optimum sensitivity and linearity. Special input provisions exist for “longstroke” LVDT's (full-scale range of ±1 inch or greater).

For each of its four analog inputs, the 10A31-4 produces two displayable outputs: one with “normal” analog filtering and one with high bandwidth characteristics. All four channels share a common sensed excitation of 100 mA (rms), maximum. For cables over 25 feet in length, this limits the distance from the sense point to the transducer to about 20 feet of 18-
gage wire.

Transducer Types which the Model 10A31-4 will accommodate are 5- or 7-wire LVDT's capable of 3280-Hz operation and having primary impedance of 80 ohms or greater (all Daytronic LVDT transducers are suitable);3- or 5-wire variable reluctance transducers with sensitivity Range: full-scale ranges from ±0.010 in. (±0.25 mm) to ±6.0 in. (±15.24 cm), when used with Daytronic or equivalent transducers. 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.
