Easy to install ESMLS04 Shear beam load cells for belt scales
Working Principle
When an external force is applied to the sensor, the web experiences shear strain, causing the resistance of the strain gauge to change. The strain gauges are usually arranged in a Wheatstone bridge, which converts the resistance change into a voltage signal output, thereby reflecting the magnitude of the external force.
Product Features
- 1. High cost-performance ratio: simple structure, mature manufacturing process, and high material utilization.
2. Easy installation: one end fixed, the other end subjected to force.
3. Excellent anti-eccentric load performance: shear stress distribution is relatively insensitive to the position of the load point.
4. Wide range coverage: mature products available from a few kilograms to tens of tons.
5. Low profile height: flat design.
6. Easy networking: standardized dimensions and output.
7. Good sealing: mature laser welding technology.
APPLICATION SCENARIOS
1. Platform scale / small floor scale: weighing with 3–4 sensor groups, stable accuracy.
2. Hopper / tank / silo weighing: chemical, food, and building materials batching systems.
3. Belt scale / quantitative packaging scale: dynamic / static weighing on production lines.
4. Truck scale / rail scale: large range, high reliability weighing.
5. Testing machine / force monitoring: material testing, equipment load monitoring.
