All load cells come with a marking such as "IP57". What does this marking tell you? This article gives a brief but detailed explanation of the Ingress Protection rating on all load cells.
Precise uncertainty calculations in force measurement require testing that can be lengthy and expensive. Instead, load cell manufacturers seek compliance to standards from organizations such as NIST, ensuring their products perform to industry-consensus tolerances.
This article presents general ways of evaluating uncertainty in force measurement applications. It also applies this information to the uncertainty figures given with load cell product specifications.
Precise uncertainty calculations in force measurement require testing that can be lengthy and expensive. Instead, load cell manufacturers seek compliance to standards from organizations such as OIML, ensuring their products perform to industry-consensus tolerances.
In load measurement applications, strain gauge load cells are a popular choice. They're cost-effective, accurate and highly configurable. Learn about strain gauge advantages and circuitry configurations.
The optical strain gauge is a versatile alternative to conventional electronic strain gauges. Their construction gives them distinct advantages in multiple applications.
Large-scale, complex weighing systems often require a combination of multiple load cells to record accurate measurements. In this case, a junction or summing box combines measurement signals from these distributed load cell devices. The load cell trimming process is crucial to ensure combined signal accuracy.
Load cell specifications generally cover three things: (1) what output voltage can you expect for a given load, (2) how much error can you expect for a given output and (3) how to safely operate the load cell. This article explains some of the most common load cell manufacturer's specifications.
Various industries have a need for weighing or measuring forces as part of performing their principal tasks. Strain gauges and piezoelectric sensors are two common transducer technologies that serve these industries.
