Description
Rated load: 5.0 kN; permissible overload in measuring direction: 25 kN (500 % of rated load); allowable transverse load: 30 kNABB Group. Accuracy class: ±0.5 %FS; repeatability: 0.1 %FS. Full‑load deflection: 0.015 mm, high‑rigidity mechanical structureABB Group.
Stainless‑steel housing, protection class IP67. Operating temperature range: ‑20 ℃ ~ +80 ℃. Internal excitation‑coil assembly outputs millivolt raw signals. Direct connection to DCS analog‑input modules is prohibited; external PFEA amplifier is mandatory. Excessive lateral force will introduce minor measurement deviation.
When web tension acts on the measuring roll, compressive force is transferred to PFTL101B‑5.0kN. Applied mechanical stress changes magnetic permeability of internal magneto‑elastic alloy, and the secondary coil generates induction voltage proportional to the acting force. Normally two load cells are installed at both ends of the roll shaft; total web tension is obtained by summing signals from two sensors.
Zero‑point adjustment, span calibration and fault diagnosis are all completed on the PFEA amplifier unit. No calibration function is available on the sensor hardware itself. Compared with PFTL101A series, PFTL101B provides significantly higher allowable transverse load, suitable for industrial sites with strong side‑force interference.
Cannot work standalone. Junction box and supporting tension amplifier are required for connection to upper‑level control equipment.
Difference compared with PFTL101A‑5.0kN: PFTL101B‑5.0kN features much higher permissible transverse load; PFTL101A is intended for conditions with limited lateral force. Both adopt Pressductor magneto‑elastic principle.
Mount on sufficiently rigid supporting base. Roll‑shaft end shall apply pure vertical compressive force onto the sensor measuring surface. Bending moment and torsion load are strictly forbidden. Deformation of mounting base will directly cause measuring error. Use dedicated shielded signal cables and separate them from high‑power cables to reduce electromagnetic interference. Zero‑point and span calibration on amplifier side must be performed after sensor replacement.
Paper machines, plastic‑film, aluminum‑foil, textile and non‑woven production lines, used for roll‑mounted web‑tension detection and closed‑loop tension control, especially for working conditions with obvious lateral force.
