DESCRIPTION

The ATA-2001 is a general purpose, AC line-powered, LVDT/RVDT analog conditioner with digital setup and

calibration. The embedded microprocessor generates a PWM-shaped sine wave and handles all calibration

functions. It also controls the demodulation, filtration and synchronization of the LVDT or RVDT transducer

signal. All settings are stored in non-volatile memory for restoration on power up. Zero, Gain and Phase

adjustments are accomplished via the use of splash-proof front panel pushbuttons and digital voltage dividers.

Intended for the most demanding industrial applications, the ATA 2001 is CE certified, and has been rigorously

tested to the highest industrial standards for EMI, RFI and ESD.

Designed for universal compatibility with 4, 5 and 6 electrical connection transducers, the ATA-2001 provides a

wide range of oscillator frequencies, gains and two excitation voltages, affording maximum interface versatility.

The very high drive current of 45mA allows operation with transducer input impedances as low as 12 Ohms

(with 0.5 VRMS excitation). With high gain capability and low noise, the ATA 2001 provides measurement

resolutions beyond any product currently available.

The unique auto fall-back synchronization feature allows reliable master/slave operation, for prevention of

amplifier cross talk, without the worry of sync signal loss. If the internal processor in a slave amplifier detects an

unstable or missing sync signal, the internal clock will take over, continuing at the pre-selected nominal

frequency. Upon restoration of a normal sync pulse, the oscillator will return to the slave mode.

The ATA 2001 is contained within a rugged, one-piece, extruded aluminum housing which provides optimal

amplifier performance under the most rigorous EMI and RFI conditions. An integral panel mounting system

provides for convenient 1/8 DIN standard, panel installation. A pre-punched 19” rack adapter is also available to

accommodate up to eight amplifiers per adapter installation.

Also see our other signal conditioner models, LDM-1000 (DIN rail mount, VDC and 4-20mA output), LVM-110

(VDC input/output), LiM-420 (4-20mA transmitter), PML-1000 (1/8th DIN panel meter, VDC, current and RS485

outputs), and our IEM-422 (NEMA-13 rated 4-20mA transmitter).
