Proven History of Successful Railway Applications
with Thousands of Railway Train Control Systems!
Meets CENELEC/AREMA Standards.
The Jewell LCF-501-R Series accelerometers are
configured specifically to yield a combination of
high accuracy and ruggedness in Outline Diagram
railway applications. The inertial sensor moving
system is supported by a taut-band torsional
suspension, which is floated in a silicone damping
fluid.
