SHORT LONGFELLOW SERIES • LINEAR POSITION TRANSDUCER
The Short Longfellow is frequently used for measuring linear
position or displacement up to 6 inches on a wide variety of
manufacturing and process equipment. The mechanical design of the
unit’s front and rear bearings, anodized extruded aluminum housing,
stainless steel shaft and precious metal wipers are suitable for a factory’s
harsh environment.
Based on the proprietary MystR® conductive plastic film, it provides
a high resolution, absolute position measurement without external signal
conditioners.
Intrinsically Safe for Class I, II, and III Division 1, Groups A, B, C, D,
E, F and G for Hazardous (indoor/outdoor) NEMA 4 locations.
V max = 30 V, I max = 100 mA, Ci = 0, uF, Li, = 0 mH.
