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.
