ABB PFTL201C

Product Brief:​

The PFTL201C is not electronic​ — it is the sensor​ (transducer) that mounts between machine frames / roll bearing housing and a reaction pad. When compressive force is applied along its axis, the internal ferromagnetic core’s permeability changes → induces proportional AC voltage in the secondary coil (excited by PFEA111/113’s AC source).

Description

ABB PFTL201C

  • Technical Specifications (typical PFTL201C — verify cert sheet):
    • Rated Force: 10 kN (other std ranges: 1, 2, 5, 20, 50, 100, 200, 500 kN)
    • Excitation: AC 5–10 V rms @ 2–5 kHz (supplied by PFEA amplifier)
    • Output Signal: ≈0–30 mV (proportional to force × excitation — exact sensitivity on calibration cert)
    • Nonlinearity: ≤0.1 % FS
    • Hysteresis: ≤0.05 % FS
    • Repeatability: ≤0.02 % FS
    • Temperature Effect on Zero: ≤0.02 % FS / °C
    • Temperature Effect on Span: ≤0.01 % / °C
    • Operating Temp.: –20 °C to +70 °C (some versions –40 °C to +80 °C)
    • Overload Capacity: 150 % FS safe (some 200 % mechanical limit — check cert)
    • Material: Alloy steel or stainless steel (nitride hardened) — cylindrical body with machined loading surfaces
    • Mounting: Sandwiched between roll bearing housing & reaction plate / load cell seat — secured by dowel pins (prevent side shift) — loaded in pure compression
    • Cable: 4-wire (Excite+/–, Sig+/–) + shield — typical length 5/10/15 m — outer jacket PUR/PE (oil/flex resistant)
    • Protection: IP67 (with proper cable gland & cap)
    • Certifications: ATEX / IECEx (some versions Ex-e / Ex-i compatible — use with barrier if Zone 1/21)
  • Functional Features / Application / Material / Structure / Working Principle / Installation / Precautions:
    • Used in pairs (left & right of a roll) to measure total strip tension = sum of two PFTL201C readings; differential indicates off-center
    • In press force: single PFTL201C under press ram to monitor forging/closing force (peak hold in PFEA113)
    • Installation:
      1. Ensure reaction seats (top & bottom) are flat, parallel, free of burrs
      2. Place PFTL201C between seats — align dowel pins (if furnished) to prevent horizontal movement — do NOT bolt through PFTL body​ (only dowel pins / set screws to locate — main load transferred through end faces)
      3. Tighten securing set screws / clamps to specified torque (AB doc — typically just enough to prevent slip, NOT to preload cell)
      4. Connect 4-wire + shield to PFEA — observe Excite/Sig pairing (miswire → reads negative or near-zero)
      5. After PFEA powered → perform tare (no load / web slack) → set FS = 10 kN → verify output with known weight or roll dead weight
    • Precautions:
      • Pure Compression Only:​ Side loads, bending moments, torque on cell degrade accuracy & may damage — use proper seats & dowel pins
      • No Shock Loading >150 % FS:​ Although mechanical limit higher, repeated shock >150 % shortens life / shifts zero
      • Cable Not Load-Bearing:​ Strain relief required — do NOT let cable support its own weight / pull on terminals
      • Tare at Zero Load:​ With web cut / roll lifted off — if impossible (continuous line) use calculated tare from known empty roll weight subtracted in PFEA — verify periodically
      • Spare:​ Keep PFEA amp spare (electronic); PFTL201C mechanical spare justified if long lead time — store in original pkg upright (no load on cell)
