What are Strain Gauges? Strain gauges convert mechanical deformation into measurable resistance changes through the piezoresistive effect. Small resistance shifts are detected using a Wheatstone bridge with amplification and temperature compensation. Common types include linear, diaphragm, rosette, torsion, and dual-parallel gauges—each suited to specific stress directions and materials. Used widely in structural testing, load and pressure measurement, and industrial condition monitoring, strain gauges provide precise data essential for safety, performance, and predictive maintenance across engineering applications.

Installation Obstacles: Invasive In-Pipe Immersion Sensors When it comes to process piping systems, temperature of in-pipe media is often a necessary measurement – and one that needs to be monitored accurately. Traditionally, in-pipe immersion sensors are used. However, invasive in-pipe immersion sensors are often not ideal for use within process piping systems. Here are 3 considerations to take before installing immersion sensors in process piping systems.
