Description
Rated load: 20 kN; extended allowable load: 30 kN; transient overload capacity: 200 kN; allowable transverse load: 10 kN. Accuracy class: 0.5%FS; repeatability: 0.1%FS.
One‑piece stainless‑steel housing, IP65 protection rating. Operating temperature range: ‑30 ℃ ~ +80 ℃, with high industrial vibration and shock resistance. Built‑in excitation coil structure outputs millivolt‑level raw signals. It cannot be directly connected to DCS analog input cards and requires external PFEA amplifier for signal conditioning. Transverse force may cause measuring deviation if excessive.
Based on magnetostrictive effect: when web tension acts on the roll, force is transferred to PFCL201C load cell, changing magnetic properties of internal magnetic material, and secondary coil outputs weak induction signal proportional to tension. Normally applied in pairs, one PFCL201C‑20kN installed at each end of the roll; total tension is obtained by summing signals from two sensors.
Zero‑point and range adjustment are not available on the sensor itself. All calibration and parameter configuration are completed on the backend PFEA amplifier. Good anti‑transverse‑force performance, only sensitive to vertical force, suitable for high‑speed continuous production lines.
Cannot operate standalone; junction box and tension amplifier are required for connection to control system.
Difference compared with PFTL series: PFTL is strain‑gauge type tension sensor; PFCL201C is magnetostrictive pillow‑block load cell with superior overload resistance for medium‑heavy‑duty tension applications.
Pillow‑base mounting. Roll shaft end presses directly onto the sensor bearing surface. Only vertical compressive force is permitted; bending moment and torsion are forbidden. The mounting base shall possess sufficient rigidity, since base deformation will result in measuring error. Use dedicated shielded cables and keep them separated from power cables to reduce electromagnetic interference. Zero‑point and span calibration on amplifier side are mandatory after sensor replacement.
Paper machines, cold‑rolled steel strip, aluminum foil, film and non‑woven fabric production lines for roll‑type tension detection and closed‑loop tension control.
- ABB Millmate PFCL201C‑20kN pillow‑block tension load cell with proprietary Pressductor magnetostrictive measuring principle, much higher overload resistance than conventional strain‑gauge sensors.
- Rated capacity 20 kN, robust stainless‑steel housing, IP65 protection for dusty and humid industrial environments.
- Outputs raw millivolt signals only; PFEA tension amplifier is mandatory, direct connection to DCS AI modules is not allowed.
- Installed in pairs at both roll ends for total web‑tension measurement, excellent anti‑transverse‑interference performance.
- No on‑board calculation or calibration; all parameters are configured on backend amplifier.
- Industrial spare part mainly used for maintenance and retrofitting of legacy production lines.
