Low price ESMLS07 Bellows Weighing Sensor Module for Hopper scale

The ESMLS07M bellows cantilever beam weighing module is a modular weighing component that integrates a sensor, mounting base, and limiting device. Centered around the bellows cantilever beam weighing sensor, it is equipped with dedicated connectors and protective structures, allowing direct installation and use without complex adjustments. The module features fully welded stainless steel bellows sealing with an IP68 protection rating, effectively resisting moisture, dust, and acid-alkali corrosion, making it suitable for harsh environments such as the food and chemical industries. Its core sensor offers high accuracy, with a comprehensive precision of ±0.02%~±0.1% FS, outstanding anti-eccentric load and lateral force resistance, and a measurement range of 5kg~500kg, meeting medium to small range weighing needs. The module has a compact and low-profile design for easy installation, can operate stably with single-sided cantilever mounting, and comes with shielded cables for stable signal transmission, allowing direct connection to weighing instruments and PLC systems. It is widely used in platform scales, hopper scales, filling equipment, batching systems, and laboratory precision weighing, combining high accuracy, reliability, and ease of operation, significantly reducing on-site installation and debugging costs, making it an ideal modular solution for industrial automation weighing and precision measurement.

    Working Principle

    When an object is placed on the ESMLS07 bellows sensor, the bellows undergo elastic deformation under pressure or tension, causing a change in the resistance of the strain gauge. The detection circuit converts this resistance change into an electrical signal, which is then amplified and filtered, ultimately producing an electrical signal proportional to the load, which is used to display the weight of the object.
