ESMLS09A1 Micro Membrane Box Sensor for packaging scales

The flat membrane box weighing sensor features an ultra-thin, flat, integrated stainless steel structure with a fully welded sealing process. Its protection level can reach IP67 and IP68, making it dustproof, waterproof, washable, and corrosion-resistant, suitable for complex working conditions such as humidity, dust, and applications in the food and chemical industries. It has a top-and-bottom surface pressure design, with low installation height and minimal space occupancy, making it ideal for embedded and countertop installations. The sensor provides excellent resistance to eccentric load and lateral forces, with uniform force distribution and strong stability. It has high rigidity, minimal deformation, and fast response, suitable for both static weighing and dynamic production line detection. It offers high overall accuracy, low zero-point drift, and stable long-term performance. With a purely compression-based structure and no moving or friction parts, it has a long service life and is easy to maintain. The standard 2.0 mV/V output is compatible with weighing instruments, transmitters, and PLC systems, widely used in industrial weighing scenarios such as platform scales, material tank batching, pressing force monitoring, automated production lines, and robotic force measurement.

Working Principle

ESMLS09A1 Membrane Box Weighing Sensor elastomer (diaphragm) undergoes elastic deformation under an external force, causing the resistance of the strain gauges pasted on its surface to change accordingly. The measuring circuit converts the resistance change into an electrical signal, which, after amplification, outputs a voltage or current signal proportional to the external force, thereby achieving the conversion from weight to electrical signal.

Product Features

1. Ultra-thin flat structure, low installation height
Slim appearance, stressed on the upper and lower surfaces, small volume, suitable for space-limited, embedded, or countertop installation.

2. Strong resistance to eccentric load and lateral force
Integrated elastomer design in the load cell, uniform stress distribution, good adaptability to eccentric loads and lateral forces, high stability.

3. High accuracy and good stability
Comprehensive accuracy 0.02%–0.1% FS, low temperature drift, long-term zero stability, suitable for industrial continuous weighing.

4. Fully sealed, high protection level
Stainless steel welded sealing, commonly IP67/IP68/IP69K, dustproof, waterproof, wash-resistant, suitable for humid, dusty, and food wash environments.

5. Fast response, suitable for dynamic weighing
Good rigidity, small deformation, fast dynamic response, can be used for batching, assembly lines, and online inspection.

6. Simple structure, mainly compression-resistant, wide applicability
Only bears pressure, not easily damaged by overload, no moving friction parts, long service life, low maintenance.

7. Easy installation, good interchangeability
Top and bottom surfaces, flange/through-hole installation, easy to fix, convenient for forming weighing modules and multi-point parallel weighing.

8. Corrosion-resistant material
Optional 304/316 stainless steel, acid and alkali resistant, corrosion-resistant, suitable for chemical, food, and pharmaceutical industries.

9. Standardized signal output
2.0 mV/V standard strain signal, compatible with all weighing instruments, transmitters, and PLCs.

10. Suitable for platform scales, press-fit testing, silo weighing, assembly line weighing, robot force measurement, and other scenarios.
