Dancer Roll Position Transducer
Press Release Date: March 31 2004
Body Text: Sussex, NJ - March 31, 2004 - Datatran Labs, inc. has introduced a heavy duty, high precision, geared potentiometer designed to provide dancer roll position feedback signals.
This industrial quality transducer has a large stainless steel input shaft, supported by double sealed and prelubricated ball bearings. The input shaft is coupled to and isolated from a conductive plastic potentiometer element by either one or two stages of precision gearing. The input shaft will handle up to 80 pounds of radial load. The potentiometer does not contain internal stops and thus cannot be damaged by excessive dancer roll travel. The unit is mounted in a steel box with a screw-on cover. Both foot and flange mounted configurations are offered.
The potentiometer is rated for 1 watt and will provide better than 1% linearity with essentially infinite resolution. The rated life expectancy, at full power, is more than 20 million complete cycles. Over 700 gear ratios ranging from .06 turns to 25 turns of the input shaft for full travel are offered. The large range of gear ratios allows the unit to provide full travel on most dancer roll installations. Full potentiometer rotation ensures that the output signal will provide the maximum resolution and contain the minimum amount of induced electrical noise. External user connections are made to a terminal block, inside the enclosure. All units will operate from -65 degrees to +125 degrees C.
Common options include special input shafts, stainless steel enclosures, zero backlash gears, low torque models, plug-in connector and electronic end of travel limit switches. The dancer position transducer is available now, directly from the factory or selected industrial distributors. List prices start at $320.00 (Quantity one).
