AZA 0931 Integral Proving Rings: The Standard for Accurate Force Calibration by Azalab

The Azalab AZA 0931 Integral Proving Rings are highly precise and indispensable instruments designed for the accurate calibration and verification of force-measuring systems in a wide range of material testing machines. These include Universal Testing Machines (UTMs), Compression Testing Machines (CTMs), spring testing machines, and other load-applying equipment used in civil engineering, metallurgy, and various material science laboratories. In an era where measurement accuracy directly impacts product quality and safety, ensuring the reliability of force data is paramount. The AZA 0931 provides a robust, reliable, and NABL-traceable solution for maintaining the highest standards of accuracy in force measurement across India.

The Principle of Force Measurement with AZA 0931 Integral Proving Rings

A proving ring is a fundamental force-measuring device that operates on the principle of elastic deformation. It consists of a precisely machined, high-grade alloy steel ring that is designed to deflect in proportion to an applied compressive or tensile load. The term “Integral” signifies that the deflection measuring device, typically a sensitive dial gauge or an electronic transducer, is directly mounted within the body of the ring, ensuring a compact and robust unit.

Here’s how it works:

1. Load Application: When a force (either compressive or tensile, depending on the ring’s design) is applied across the diameter of the ring, it causes a slight elastic deformation or deflection.
2. Deflection Measurement: This deflection is accurately measured by the internal dial gauge or electronic transducer, which is mounted diametrically across the ring.
3. Calibration Factor: Each AZA 0931 Integral Proving Ring comes with a unique calibration certificate. This certificate provides a “calibration factor” or a graph that relates the measured deflection (in divisions on the dial gauge or units from the transducer) directly to the applied force (in kN or kgf). By applying known loads using the proving ring, testing machines can be accurately calibrated, ensuring that their indicated load values are correct and traceable to national/international standards.
