Roll Force kelk

KELK Strain Extensometers. Extensometers are simple, economical sensors attached to rolling mill housings to measure the strain in the housing posts resulting from roll force. Roll force can be derived from these measurements, but due to outside influences, these calculated results can never be as accurate as direct load cell force measurement.
