Understanding strain gauge
It converts force, pressure, tension, weight, etc. into a change in electrical resistance that is then measured. A strain gauge is a sensor whose resistance varies with applied force. Stress and strain happen when outside forces are applied to a stationary item. Stress and strain are terms used to describe opposing internal forces within an…
Understanding Pirani Gauge
by
The Pirani gauge is a reliable thermal conductivity gauge that is used to monitor pressures in vacuum systems. Marcello Pirani came up with the idea in 1906. By effectively using a resistance thermometer as the heated element, the Pirani gauge eliminates the use of a thermocouple to detect temperature (as in the thermocouple gauge). In…
Understanding Pressure Gauge
by
A pressure gauge is a device that measures the amount of fluid in a container. Pressure gauges are necessary for setting up and regulating fluid power equipment, as well as troubleshooting them. Fluid power systems would be unpredictable and unreliable without pressure gauges. Gauges verify that there are no leaks or pressure variations that could…
