Signal conditioner made for demanding industrial applications

The ATA-2001 from Measurement Specialties is a general purpose, AC line-powered, LVDT/RVDT analog conditioner with digital setup and calibration. Intended for the most demanding industrial applications, it is CE certified and has been rigorously tested to the highest industrial standards for EMI, RFI and ESD. 

The ATA-2001 is rich with features. Its 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. In addition, all settings in the ATA-2001 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. 

Designed for universal compatibility with four, five and six 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 45 mA allows operation with transducer input impedances as low as 12 Ohms (with 0.5VRMS 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 offers convenient 1/8 DIN standard panel installation. A pre-punched 19-inch rack adapter is also available to accommodate up to eight amplifiers per adapter installation. 

Ideal applications include: power-gen turbine control, head box slice lip position control, roller gap position feedback and precision metrology labs.

The ATA-2001 Analog LVDT/RVDT Signal Conditioner is available from Durham Instruments, a provider of measuring instruments based in Pickering, Ont. For more information on ATA-2001, contact Durham Instruments.
