Zemic HM9B Load Cell
The Zemic HM9B Load Cell is one of the types of load cells produced by Zemic. This type is a dual shear beam load cell. It converts applied shear stress into an electrical signal output. It is highly recommended for applications with much electronic weighing equipment like tracks, trucks, and hoppers. It is made from nickel plated alloy steel which is durable to handle large weights.
The Zemic HM9B is made of nickel plated alloy steel. This ensures the load cell’s improved hardness, durability, toughness, and ability to withstand corrosion. Alloy steel is also used in jet engines, nuclear power plants, and other spacecraft.
The weighing accuracy class of the Zemic HM9B load cell is OIM R60 C3. The C3 accuracy class is given to load cells with high accuracy specification. Load cells in the C3 Accuracy Class classification are mostly used with weighing machines used for mixing different construction materials like sand and cement.
The maximum compression force capacity of HM9B load cells can range from 10t to 50t. Overload is allowed but to a certain extent only.
The safe overload capacity of this load cell is 150% of its maximum load capacity. Exceeding 150% may put the load cell in danger of being deformed.
The maximum overload allowed is 300% of the maximum load capacity. Exceeding 300% will deform the load cell and cause inaccurate measurements.
Load cells need to be properly mounted in the right position. Improper mounting of the load cells will result into wrong readings and inaccurate results. Overloading weighing device is sometimes unavoidable which may result permanent deformation of the load cell. Permanent load cell deformation will make calibration impossible. Another common problem with load cells is electrical damage. Being exposed to significant electrical currents damage the resistors in the load cells.
