High precision and stability ESMLS04M Shear Beam Weighing Sensor Module for Platform scale
Working Principle
The cantilever beam weighing module is based on the strain measurement principle. Its core is an elastic beam fixed at one end and free at the other. When a load is applied to the free end, the beam bends, with the top surface under tension and the bottom surface under compression. Strain gauges pasted on the surface of the beam deform accordingly, causing a change in resistance.
Four strain gauges form a Wheatstone bridge, converting the resistance change into a faint voltage signal proportional to the weight. The module's unique spherical pressure head automatically eliminates eccentric load and installation tilt errors, while the limit device resists horizontal impact forces. Finally, the instrument amplifies this signal and converts it into a weight reading, achieving high-precision and stable weighing.
Product Features
1. Extremely easy to install: plug and play, no complex adjustments required
2. Strong resistance to eccentric load / lateral force: spherical support self-aligns, minimal eccentric load error
3. Good stability: vibration and shock resistant, minimal long-term zero drift
4. Reliable protection: fully sealed, suitable for humid, dusty, and corrosive environments
5. Simple maintenance: easy to replace and calibrate
APPLICATION scenarios
1. Industrial Tank Weighing: Silos, reaction kettles, mixing tanks, storage tanks (3~4 point support)
2. Platform Scales / Small Floor Scales: Logistics, warehousing, workshop floor weighing
3. Batching Systems: Quantitative batching scales for chemical, food, and pharmaceutical industries
4. Conveyor / Packaging Scales: Dynamic check weighing and packaging measurement on production lines
5. Warehousing / Tank Level Monitoring: Converting weight to determine material levels
