About the ATA-2001 LVDT & RVDT Amplifiers

The ATA-2001 LVDT Amplifier is a general purpose, AC line-powered LVDT/RVDT conditioner featuring state-of-the-art design principles. The new SMT (Surface Mount Technology) design uses an embedded microprocessor to generate a PWM-shaped sine wave and control all calibration functions. The processor is also employed in the
demodulation, filtration and synchronization of the LVDT signal. All settings are stored in non-volatile memory for
restoration on power up. Zero, Span and Phase adjustments are accomplished via the use of splashproof front Panel pushbuttons and digital voltage dividers, eliminating the need for drift-inducing screw adjust potentiometers. All amplifier controls are accessible outside of the rugged aluminum enclosure.

The new ATA 2001 is CE certified, and is intended for the most rigorous, industrial applications. The ATA 2001
has been tested to the highest industrial standards for EMI, RFI and ESD. The ATA 2001 is designed for universal
compatibility with all 4, 5 and 6 lead LVDTs. A wide range of oscillator frequencies combined with two excitation
voltages, 3.5 and 0.5 Vrms, provide maximum versatility. The high power carrier amplifier has more than twice the
drive capability of previous designs. Able to power low impedance LVDTs at higher amplitudes, the ATA 2001 provides measurement resolutions beyond any product currently available. The ATA 2001 is contained within a rugged, extruded aluminum housing. The one-piece design 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. Pre-punched 19”
rack adapters are available from Althen to accommodate up to eight amplifiers per adapter installation.
