High resolution - Industrial ruggedness

The Gurley HR2A High-Resolution Interpolator is a versatile electronics package that augmentsyour Gurley encoders capabilities, improving resolution by as much as 80x. The units may beused with virtually all available counter circuits, dedicated encoder interface cards andprogrammable logic controllers.The HR2A interpolator can generate any number of quadrature square waves from 1 to 20 timesthe line count on the disc or scale, or fixed duration pulses at 1, 2, or 4 times any interger from 1
to 20.It features an on-board low-dropout voltage regulator. Optional up/down or pulse/directionoutput formats are available. A zero-index (reference) signal is available in gated ҽ cycle, gated cycle, or fixed duration pulse format to give you greater flexibility. Advantages: Gurley Precision Instrumentsܒ philosophy of using lower resolution discs or scales coupled with
electronic interpolation has several distinct advantages. Highly accurate and stable optical signals are easy to obtain. Final encoder resolution and frequency response can be extended beyond the naturalphysical limits imposed on direct readout techniques. A greater variety of resolutions can be derived from existing optical masters. Mechanical positioning of the optical components is less critical, which enhances long-termstability and reliability with regard to vibration and temperature. >
