Strain Gauge Basics – Part 2 – Shunt Calibration
As mentioned in the previous post, in order to relate the measured voltage difference across the bridge circuit to a strain measurement, we need a way of calibrating the system. In most systems, including the Prosig acquisition systems, this is done by including a high-precision shunt resistor across one of the legs in the bridge.…
Bearing & Gearbox Vibration Analysis Using Demodulation Techniques (Part 1)
Bearings and gearbox vibration are fundamental issues for rotating machines in many industrial applications. These are critical components; any failure can prove expensive in repair costs and downtime. Because of this condition, monitoring has become increasingly important over the years, usually centred around vibration measurements taken at critical locations, either continuously (online) or as part…
Strain Gauge Basics – Part 1
The use of strain gauges with Prosig’s data acquisition systems is well understood and has been used in many real-world applications over the years [see What Is A Strain Gauge? by James Wren here on the blog and also available as Strain Gauges Explained in the Prosig Noise and Vibration Measurement Handbook]. The following post…
