The Honigmann RFS® 150 E is a single roll tension sensor designed to measure the running line tensions of yarn, wires, optic fibers, cables, tapes/bands, wraps/webs, foils and similar process materials. Existing rollers with 20-180 degree wrap angles can be converted for use as RFS measurement locations.

The RFSE features a unique strain-gauge design delivering extremely precise and stable measurements providing maximum overload protection. They are used in a variety of low and high-range applications, such as measuring 1 or 2 grams on fine denier yarns/fibers to applications measuring wire/cable up to 500 Kg.

High precision mechanical design ensures the calibrated accuracy of the RFS remains unchanged throughout the sensor’s service life. The measurement is not influenced by the force introduction point, i.e. the sensor is not affected by lever arm action or any axial tilt torques which might occur.

Measurement Principle
The force acting radially at the bearing journal, along the measurement vector, causes a microscopically small, elastic deformation of the complex load cell. This deformation is registered at a pre-determined position by way of strain gauges and is then evaluated electronically. The high mechanical stiffness of the load cell enables measurement with virtually no excursion. This tension measurement principle is based on the evaluation of the force applied radially and transferred to the sensor by way of the bearing journal. This force is determined by the reversing geometry and the line tension.

The RFSE features a built-in strain-gauge amplifier providing a 0-10 VDC or 4-20 mA output proportional to the capacity. This sensor requires an unregulated 24 VDC power source and only requires a "zero" adjustment via adjustment pot on the rear portion of the sensor body.
