Omnicoder™ Non-Integral Encoder

|||||
| Miranova Systems has developed a new breed of optical encoders. While packaged in an industry standard shell, the Omnicoders’™ proprietary features prove to be anything but standard. Outputs ranging from 0.001 to 4999.999 counts per revolution coupled with re-programmability allow unparalleled versatility over any other encoder. Accurate to nearly one arc minute with a high frequency response of 125 KHz suits most applications requiring speed and precision. The Omnicoder™ uses a virtually indestructible Mylar disc to read position, offering superior durability over the more common glass disc. With a standard operating temperature range of -40°C to +85°C, extreme environmental conditions do not present a problem. All of these features form a new tool for the industry, offering a solution for countless applications. With speed, flexibility and accuracy, the Omnicoder™ performs where other encoders cannot. Applications: Printing Industry A printing press manufacturer needed to synchronize two web presses. After setting up the presses, he discovered one press had an oversize drum that ran at slightly less RPMs than the other press, 0.9733281332935 less to be exact. The first press had a 1,000 count encoder attached to it and would normally be used to drive the second press. Traditionally, a gear train would have to be constructed to drive a second encoder at the required counts per revolution. The solution was to attach an Omnicoder™ to the first press with a non-integer output of 973.328133 counts per revolution. The second press receives its output drive signal from this non-integer output. Problem solved. Film Manufacturing A film manufacturer designed a machine to put marks on film every half inch. The film passes over a drum that is 9.0 inches in diameter. They required the marking pulse to be accurate to within 0.01 inches over an 8-hour shift. The solution was to use an Omnicoder™ attached directly to the drum with the output pulses triggering the film marking tool. The output of the Omnicoder™ was programmed for 56.64866764616278292327 counts per revolution. With this setup, the Omnicoder™ was able to sustain accuracy to within 0.001413 inches, and would maintain this over the life of the encoder. Oil Well Logging A well logging company wanted a simple way to indicate the depth of his well logging instrumentation in 0.01-inch increments. The solution was to connect an Omnicoder™ to a 6.0-inch sheave over which the instrument cable passed. The Omnicoder™ was programmed for 1884.95559215387594307758 counts per revolution. When attached to a simple quadrature counter readout, he had a depth indication in inches with accuracy that exceeded his highest expectations. Bottle Filling Machine A special feature of the Omnicoder™ is the ability to output two independent quadrature signals, each with a different count per revolution. This feature was taken advantage of by a bottle manufacturer who realized considerable savings in synchronizing two parts of a bottling machine from the conveyer belt drive. The Omnicoder™ was attached to the drive roller of the conveyor belt to connect the different parts together. |
