Zemic BM11 Introduction
The Zemic BM11 is a stainless‑steel, single‑ended bending beam load cell designed for high‑precision weighing in industrial and commercial applications. With its hermetically sealed IP68 construction and OIML R60 C3/C4 certification, this loadcell offers excellent protection against moisture, dust, and harsh environmental conditions. The BM11 is widely recognized among load cells for its long‑term stability, consistent accuracy, and reliability in continuous operation. Thanks to its compact design and flexible mounting options, it is often considered a near‑universal solution for medium‑capacity weighing systems, even though it is primarily intended for compression rather than tension measurement.
Installation
Correct mechanical installation is essential to fully benefit from the accuracy of the BM11 load cell:
1- Mount the loadcell on a flat, rigid base using the recommended fixation bolts (M8 or M10 depending on capacity).
2- Ensure the mounting surface is clean, level, and free from deformation to avoid unwanted bending stresses.
3- Use proper mounting accessories or feet to allow controlled horizontal movement while preventing lift‑off.
4- The load introduction point must be positioned exactly as specified to maintain correct bending beam behavior.
5- Tighten all bolts to the recommended torque values and avoid over‑tightening, which may affect sensor performance.
Loading
For reliable and repeatable weight measurement:
1- Apply the load vertically in compression on the designated loading area of the load cell.
2- Distribute the load evenly to prevent eccentric loading, which can reduce accuracy and sensor lifespan.
3- Avoid side forces, shock loads, and dynamic impacts, even though the BM11 supports 150% safe overload and 300% ultimate overload.
4- The BM11 is not intended for tension applications; using it in pull‑type setups may compromise performance.
5- After installation, allow the sensor to stabilize before performing zero adjustment and system calibration.
Zemic BM11 Applications
– Commonly used in platform scales, bench scales, and floor scales requiring high‑accuracy zemic load cells.
– Ideal for belt scales, bagging machines, and automated weighing systems with medium capacity ranges.
– Well‑suited for smaller hopper and tank weighing systems operating under compression loads.
– Reliable choice for industrial environments demanding hermetically sealed, IP68‑rated loadcell solutions.
– Frequently selected in OEM projects where consistent performance and long‑term stability are essential.
– Acts as a versatile and almost universal weighing component for compression‑based applications, though not suitable for tension measurement.
