As a supplier of genuine E+L (Erhardt+Leimer) parts in Bangladesh, Prime Engineering explains what these E+L load cells do, which model your machine likely uses, and how to choose the right replacement.
What Is an E+L Load Cell?
An E+L load cell is a force transducer mounted on a roller shaft that measures the tension of the fabric or web passing over it. As the fabric pulls against the roller, the load cell’s strain gauge bridge deforms slightly and converts that mechanical force into an electrical signal, which is sent to the machine’s tension controller. The controller then adjusts motor speed or braking to keep web tension constant.
A properly working E+L load cell gives you:
- Accurate, real-time tension measurement, essential for consistent fabric feed and finish quality
- Automatic tension correction, since the controller reacts to the load cell’s signal continuously
- Overload protection, preventing fabric damage from sudden tension spikes
- High measuring accuracy, even across a wide range of forces depending on the fabric type and process
- Long service life when properly matched to shaft diameter and load range
E+L Load Cell Series Prime Engineering Can Supply
PD 21/22 — Flange load cell, steel
The most common E+L load cell type, available across shaft diameters from 12 mm to 65 mm and measuring forces from 0.05 kN to 10 kN. Suited to most stenter, dyeing, and slitting line tension points.
PD 25/26 — Flange load cell, aluminum
A cost-effective, anodized aluminum alternative to the steel PD 21/22, used where a lighter-duty or budget-friendly option fits the application.
PD 23/24 — Stainless steel flange load cell
Built for harsh ambient conditions — moisture, chemical exposure, or corrosive environments — common in wet-processing and dyeing sections.
PD 27 — Flange load cell for rollers with single-end bearings
A lower nominal force (60 N) design specifically for rollers supported on one end only.
PD 50 — Block load cell
Offers a large measuring range with a 1:25 resolution ratio, used where tension varies significantly during a process.
If you’re not sure which model your machine needs, check the nameplate on the existing load cell for the shaft diameter and nominal measuring force (kN) — send us a photo and we’ll confirm the exact replacement.
Signs Your E+L Load Cell Needs Replacement
- Tension readings on the control panel are erratic, frozen, or read zero
- Fabric tension visibly fluctuates even though the controller shows a stable setpoint
- Fabric wrinkling, stretching, or uneven feed despite no mechanical fault elsewhere
- Visible damage, corrosion, or bent flange on the load cell body
- Tension fault or sensor-error codes on the machine’s controller
Because a load cell failure often looks like a fabric or mechanical problem at first, it’s worth checking the sensor and its wiring before assuming the issue is elsewhere on the line.

Frequently Asked Questions
What does the “nominal measuring force” on a load cell mean?
It’s the maximum rated force (in kN or N) the load cell is designed to measure accurately — matching this to your process tension range is critical for both accuracy and load cell lifespan.
Can a load cell be repaired instead of replaced?
Strain-gauge load cells are sealed precision components; once the internal gauge or bridge is damaged, replacement is almost always more reliable than repair.
How do I know which shaft diameter I need?
Measure the roller shaft where the load cell mounts, or check your machine’s original documentation — E+L flange load cells are available in diameters from 12 mm to 65 mm.
