Description
The LongFellow ®II incorporates design innovations to increase
transducer life and provide greater resistance to vibration, while
providing a smooth high -quality signal for demanding factory
control applications. 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 extrude the full length of the housing to insure smooth
operation even under severe side load conditions.
The newly designed internal components provide improvements
based on worldwide testing and field experience.
Intrinsically safe for Class I, II and III Division I, 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, Li,=0mH.
