Calibration Weight: Magnetic Permeability ≤1.05

Component Specifications

Definition

A calibration weight is a precisely manufactured mass standard with certified accuracy, used to verify and adjust the measurement accuracy of weighing instruments. These weights are traceable to national or international measurement standards and are essential for maintaining measurement integrity in quality control, laboratory testing, and production processes where precise weight measurements are critical.

Working Principle

Calibration weights operate on the principle of gravitational force comparison. When placed on a weighing scale, the weight exerts a force proportional to its mass due to gravity. The scale's load cell or mechanical system converts this force into an electrical signal or mechanical displacement, which is then compared against the known mass value of the calibration weight to determine measurement accuracy and make necessary adjustments.

Materials

Stainless steel (typically 316L or 304), brass, cast iron, or aluminum with protective coatings. High-precision weights may use austenitic stainless steel for minimal magnetic permeability and corrosion resistance.
