Utilizing an incremental encoder as the sensor, the UniMeasure EP Series position transducer provides a quadrature square wave output. With interface electronics capable of times 2 or times 4 counting mode, a true resolution increase of 2 or 4 may be obtained. .
The actual resolution of an EP transducer differs slightly from unit to unit because of tolerances associated with the wire rope diameter and the capstan upon which the wire rope winds.
In applications where the output count is interpreted as a percentage of total travel, resolution differences from unit to unit are not critical. In applications where the digital output is to be interfaced to a digital display to give an output in engineering units, the calibration constant supplied with the transducer may be used to calculate a suitable scale multiplier to produce the correct engineering units.
