LONGFELLOW® II METRIC SERIES • LINEAR POSITION TRANSDUCER
The new Longfellow II Metric Series has a rugged long-life design
featuring greater resistance to vibration and a smooth high quality
signal. It has a solid stainless steel shaft, longer front-end bearings, a
vibration-free damped element, a spring-loaded ball joint and a high
precision precious metal wiper. Carrier guides extruded the full length
of the housing insure smooth operation even under severe side load
conditions.
The Longfellow II Metric is a direct drop-in replacement for existing
Waters, Data Instruments, Novotechnik, Gefran or Sfernice units. The
newly designed internal components provide improvements which
were developed after worldwide testing and field experience.
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,
