Description
Rated load: 2.0 kN; safe overload: 150 % of rated load; ultimate breaking load: 3‑times rated load. Combined measurement error: ±0.5 %FS; repeatability: 0.1 %FS. Sensitivity: 2 mV/V ±0.1 %.
Stainless‑steel housing, protection class IP65. Operating temperature range: ‑20 ℃ ~ +80 ℃. Built‑in magnetostrictive coil assembly, outputs millivolt‑level raw signals. Raw output cannot be directly connected to DCS analog‑input modules; external PFEA amplifier is mandatory. Excessive lateral force will cause measurement deviation.
Tension force from the roll shaft acts on PFTL101A‑2.0kN load cell and changes magnetic properties of internal alloy material, generating induced voltage proportional to applied tension on secondary coils. Normally two sensors are installed at both ends of the measuring roll; total web tension is obtained by summing signals from 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. Optimized for light‑to‑medium tension‑measurement conditions.
Cannot operate independently. Junction box and matched tension amplifier are required for connection to upper‑level control equipment.
Difference compared with PFCL201C series: PFTL101A‑2.0kN is compact pillow‑block sensor for light‑medium tension; PFCL201C series features higher overload resistance for heavy‑duty tension applications.
Mounted on rigid supporting base. Roll‑shaft end shall apply pure vertical compressive force onto sensor measuring surface. Bending moment and torsion load are strictly prohibited. Deformation of mounting base will directly lead to measuring error. Use dedicated shielded signal cables and separate them from high‑voltage 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, used for roll‑mounted web‑tension detection and closed‑loop tension control.
- ABB Millmate PFTL101A‑2.0kN Pressductor pillow‑block tension load cell for light‑to‑medium web‑tension measurement.
