Description
Rated load: 1.0 kN; permissible overload in measuring direction: 5.0 kN (500 % rated load); allowable transverse load: 10 kN. Accuracy class: ±0.5 %FS; repeatability: 0.1 %FS. Full‑load deflection: 0.012 mm, high‑rigidity mechanical structure.
Stainless‑steel housing, protection class IP65. Operating temperature range: ‑20 ℃ ~ +70 ℃. Internal excitation‑coil assembly outputs millivolt‑level raw signals. Direct connection to DCS analog‑input modules is prohibited; external PFEA amplifier is mandatory. Excessive lateral force will cause minor measuring deviation.
When web tension acts on the measuring roll, compressive force is transferred to PFTL301E‑1.0kN. Applied mechanical stress changes magnetic permeability of internal magneto‑elastic alloy, and the secondary coil outputs 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 PFTL101 series, PFTL301E features compact installation dimension, optimized for narrow‑width web production lines.
Cannot operate independently. Junction box and supporting tension amplifier are required for connection to upper‑level control equipment.
Difference compared with PFTL101A‑1.0kN: PFTL301E has smaller overall footprint for limited installation space; PFTL101A is standard size for general‑purpose tension measurement. 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. Mounting‑base deformation will directly lead to 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 with narrow web width, for roll‑mounted web‑tension detection and closed‑loop tension control.
