Description
Rated load: 2.0 kN; permissible overload in measuring direction: 10 kN (500% rated load); allowable transverse load: 30 kN. Accuracy class: ±0.5 %FS; repeatability: 0.1 %FS.
Stainless‑steel housing, protection class IP67. Operating temperature range: ‑20 ℃ ~ +70 ℃. Deflection under full load: 0.015 mm, high rigidity structureABB Group. Internal excitation‑coil structure outputs millivolt raw signals, direct connection to DCS analog input modules is prohibited; external PFEA amplifier is required. Excessive lateral force will bring minor measuring deviation.
When web tension acts on the measuring roll, compression force is transmitted to PFTL101B‑2.0kN. Mechanical stress changes magnetic permeability of internal magneto‑elastic alloy, and secondary coil outputs induction voltage proportional to applied force. Normally two sensors are installed at both ends of the roll shaft; total web tension is obtained by summing signals of two load cells.
Zero‑point adjustment, span calibration and fault diagnosis are all completed on PFEA amplifier unit; no calibration function is available on sensor hardware itself. Compared with PFTL101A series, PFTL101B provides much higher allowable lateral force, more suitable for industrial sites with large side‑force interference.
Cannot operate independently. Junction box and supporting tension amplifier are necessary for connection to upper‑level control equipment.
Difference compared with PFTL101A‑2.0kN: PFTL101B‑2.0kN supports much higher permissible transverse load; PFTL101A is for applications 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 sensor measuring surface. Bending moment and torsion load are strictly forbidden. Mounting‑base deformation 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 must be performed at amplifier side after sensor replacement.
Paper machines, plastic film, aluminum foil, textile and non‑woven production lines, for roll‑mounted web‑tension detection and closed‑loop tension control, especially for working conditions with obvious lateral force.
