Model FH and FV Tension Transducers

The F series transducer is a heavy-duty, flat transducer designed to accurately measure web tension in machines having live-shaft idler rolls.

One F transducer mounts under the pillow block bearing at each end of the roll shaft. Designed for use in demanding tension measurement environments, the F transducer shell has a single-piece aluminum base with a removable stainless steel top plate. A rubber seal between the base and top plate prevents water intrusion or other contamination. The transducer’s electrical connector is located at the end of a short cable for simpler access during installation.

The F series transducers supersede the former UPB style tension transducers.

The F transducer is available in a V (vertical) configuration for use when the applied force is roughly perpendicular to the top plate of the transducer. It is also available in an H (horizontal) configuration for use when the applied force is oriented more parallel to the transducer top plate. The F transducer mounts on a stable machine frame surface using one bolt (size 2), or two bolts (size 3) on each end.

The F transducer is available in two sizes. Load ratings range to 1200 lbs in the size 2 and 5000 lbs. in the size 3.


  • Corrosion-resistant stainless steel and aluminum construction.
  • Attached cable with amphenol connector.
  • Tethered top plate safety feature prevents separation from transducer in the unlikely event of beam breakage.
  • Robust overload protection. Load stops limit beam deflection to 125% of rated output.
  • Designed to meet CE mark requirements for Measurement & Control equipment: EN61326 for EMI.
  • Designed to meet the IP 65 standard for ingress protection.


  • Low-maintenance design.
  • Entire length of top plate is clear for pillow block installation.
  • Can be installed in any orientation.
  • Mechanical stop provides protection from overloads.
  • Splash resistant.
  • Use with live-shaft or dead-shaft idler rolls.


  • Drill and Tap (D&T). Drill and tap the top plate.
  • Extended Range output (XR). Produces twice the output signal for a given load rating. Must be used with electronics having extended range option.
  • Oversized Top Plate (OTP). For mounting of oversized pillow block bearing
  • Permanently Attached Cable with Tinned Leads (PT). Instead of cable connector.

Note: Some people refer to tension transducers as load cells. That's okay.
