Multi-capacity load cell prototype

Abstract

<p class="Abstract"><span>This article illustrates an advanced approach in force measurement standards. It gives a spot on the design, manufacturing and evaluation for a prototype of force transducer with multi-capacity. This prototype has three adjustable capacities (5kN, 10kN and 15kN) and works on compression mode. The introduced design offers a comparative load cell looking forward to replace three force transducers with the same capacities (5kN, 10kN and 15kN) which are commercially available. Experimental results reveal satisfactory agreements with that calculated with analytical method and results simulated using finite element techniques. The detailed metrological characteristics of this multi-capacity load cell will be published later.</span></p>

Difference between calibration and practical force proving instruments

“…Precision load cells are used to disseminate traceability from primary standard to working standards through secondary and reference standards. Load cells represent one form of the electrical force proving instruments, and may be characterized as transfer or working standards based on their metrological characteristic [2]. Load cells are based on using special designed structures which perform elastically in a predictable and repeatable manner in relative to the applied force, which is translated into a voltage by the resistance change in the intimately bonded strain gages on the sensor structure.…”
