The M1890-R

AVG Automation would like to introduce you to a unique position encoder, the Programmable Position Transducer or PPT. The PPT is an absolute position sensing device which accepts resolver inputs, converts position data to 5-digit BCD output, and is prescalable and presettable over a wide-range of electronic gear ratios. It operates in a single-or multi-turn mode with high-accuracy and can resolve linear distances of 1 part in 100,000 whether it be 0.001" (0.025 mm) over 100" (2540 mm) or 1 foot (304.8 mm) over 18.93 miles (30.46 km) of travel.

The versatile electronic design assures simple interface to other limit setting or control devices. The PPT consists of two parts, one is a position sensor mounted on the machine shaft and the other is a  programma-ble unit mounted in the machine control panel.

The position data from the sensor is converted to binary data by an internal ratiometric converter in the programmable unit, processed in the microprocessor together with other program variables and displayed on the front panel display. A parallel BCD output is also made available to provide information to other systems requiring positional data.
