Do you want to weld (and not glue) your strain gauge? Then you will learn the necessary steps here. This is a step-by-step tutorial on strain gauge welding.
This article gives some hints on how to perform lead-free soldering of strain gauges professionally and how to ensure a high reliability in your measurement.
In this article, you can get an introduction to fiber-reinforced composites.
PCBs are exposed to mechanical and thermal impacts not only during their manufacturing process but also during their transport and action. Strain values are the only reliable calculations for measuring the mechanical deformation of PCBs.
Installing strain gauges on concrete surfaces does not have to be difficult. Bear in mind three key criteria and the rest will be a cakewalk. Read on to find out what these criteria are and what you have to take into account.
Keep cool and get reliable measurement results with strain gauges even when the temperature changes. The article explains what you need to know!
In this tutorial, you will learn how to set up strain gauge rosettes using HBK's catman®AP data acquisition software and a QuantumX MX1615 data acquisition system.
Using shunt resistors to check strain gauge measuring systems is common. This paper describes that with improved 3-wire and 4-wire techniques, shunt signals can serve as precise calibration signals.
This article describes the basic principles of strain measurement using strain gauges, from the strain itself via the variation in resistance to the eventual electrical signal, and compares the magnitude of error of the voltage-fed bridge circuit and the current-fed circuit.
