Keli QS Load Cell
Description
The Keli QS Load Cell is one of the types of load cells produced by Keli. It has a steel ball loading configuration. Its recommended applications are with truck, railway, blending and almost all weighing devices. The Keli QS load cells are made of alloy steel. Alloy steel is known for its strength and ability to handle large loads.
Built Material
The Keli QS load cell is manufactured using nickel-plated alloy steel. This ensures the load cell’s improved hardness, durability, toughness, and ability to withstand corrosion. This load cell is commonly used in railways scales and truck scales.
Accuracy
The weighing accuracy class of the Keli QS load cell is OIML 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 tank weighing and light scales.
Maximum Capacity
The maximum compression force capacity of QS load cells ranges from 5t to 50t. Overload is allowed but to a certain extent only.
Safe Overload
The maximum 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.
Ultimate Overload
The maximum overload allowed is 200% of the maximum load capacity. Exceeding 200% will deform the load cell and cause inaccurate measurements.
Common Problems
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.
