ESMLS09 miniature membrane box-type load cell sensor for platform scales

The ESMLS09 micro load cell weighing sensor adopts an integrated load cell structure design, featuring a compact size and low profile, specifically designed for high-precision pressure and weight measurement in confined spaces. The sensor core uses high-quality metal elastomer and built-in high-precision strain gauge Wheatstone bridge. When force is applied, the elastomer undergoes slight deformation, accurately converting the physical force into an electrical signal output, with excellent linearity and repeatability. The product is compact and sturdy, with strong resistance to off-center load and lateral force, low alignment requirements during installation, and convenient to use. The overall design is sealed, providing good protection and adaptability to complex industrial environments such as humidity and dust. The sensor covers a wide measurement range, responds quickly, is highly stable, and supports multiple standard signal outputs, making it easy to interface with data acquisition devices and control systems. It is widely used in 3C electronics assembly, medical devices, automation equipment, small-scale dosing systems, robotic force control, and precision testing equipment, making it an ideal choice for force measurement and weighing in small spaces requiring high precision.

    Working Principle

    ESMLS09 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. The membrane housing is made of stainless steel or alloy steel.
    2. It is flat and round in shape, with a compact structure.
    3. It resists lateral forces and eccentric loads.
