Precision in the Toughest Conditions: How Shear Beam Load Cells Work
Single ended shear beam load cells are robust force sensors designed to measure loads applied in a shearing direction — that is, parallel to the sensing axis. Unlike bending beam cells, these rely on shear strain detection to provide more stable and accurate measurements under fluctuating or dynamic load conditions.
The working principle is simple: the load applied at one end of the beam causes shear strain, which is captured by bonded strain gauges. This converts mechanical force into an electrical output (typically 2.0 mV/V), allowing precise digital readouts for industrial weighing applications.
These cells are typically bolted at one end, with the other end free to flex slightly under load — making them ideal for dynamic or partially distributed weight loads.
Load Cells by Sands Industries
Precision Force Measurement from Milligrams to Megatons
Sands Industries supplies high-accuracy load cells for industrial, OEM, and research applications. From crane overload protection to automated filling systems and sim racing pedals, our load cells are designed for performance, repeatability, and integration. We offer custom engineering and local support for projects across Australia.
Dual-Purpose Force Detection: Tension & Compression
Though they’re mostly used in compression mode (e.g., in tanks, silos, and platforms), single ended shear beam load cells can also be used in tension if mounted correctly.
In Compression:
- Platform Scales: Mid- to large-scale weighing platforms
- Hoppers & Mixing Vats: Batch weighing in food and chemical plants
- Tank & Silo Scales: Bulk material level monitoring
In Tension:
- Suspended Bins or Feeders
- Conveyor Belt Weighing
Because they offer high resistance to off-axis loading, shear beam cells outperform many other types in mixed-use scenarios. Their low profile also makes them easier to integrate into existing industrial frameworks without structural modification.
Built for Harsh Industrial Environments
Engineered for durability, these load cells are typically constructed using tool steel or stainless steel with hermetic sealing or welded housings. Many models comply with IP67/IP68 protection ratings, making them suitable for:
- Dusty and powder-intensive environments (e.g., flour mills, cement plants)
- Wet or washdown areas (e.g., meat processing, dairy facilities)
- Outdoor installations (e.g., grain silos or livestock feeders)
In industries where shock, vibration, or thermal cycling is a concern, shear beam designs offer more stability than other form factors. Some models also include built-in damping to reduce signal noise.
Wiring, Calibration, and Safety Best Practices
Proper installation and calibration are essential to achieve accurate and consistent results from a shear beam system.
Installation Tips:
- Mounting Surface: Must be rigid and level to avoid mechanical distortion
- Orientation: Load must be applied parallel to the sensing axis only
- Anti-Lift Restraints: Required to avoid side-load or tipping damage
- Mounting Kits: Use factory-recommended load cell mounts with integral stops and checking
Electrical Wiring:
- Use shielded 4-wire or 6-wire cables (for remote sensing compensation)
- Keep distance from motor cables to avoid EM interference
- Connect to digital indicators, PLCs, or industrial weighing terminals
Calibration:
- Start with zeroing under no-load conditions
- Calibrate with known weights (dead load method preferred)
- For legal-for-trade applications, use certified calibration weights
Safety Checks:
- Overload Protection: Mechanical limiters or bumpers
- Grounding: Prevents damage from static or lightning
- Ingress Sealing: Use IP67/IP68-rated cells for washdown areas
