I’m often asked whether the Prosig P8000 systems support strain gauges. And what configuration of strain gauge bridges are supported? The answer is all types of all the different configurations. Continue reading Does the P8000 support strain gauges? And which types?3502class="post-3502 post type-post status-publish format-standard hentry category-p8000 category-tutorial tag-bridge tag-bridge-resistor tag-cables tag-resistance tag-strain-gage tag-strain-gauge"
The cable resistance can be a significant factor in the accuracy of the overall measurement. It is very important indeed to consider this point.
Prosig software allows the cable resistance to be entered by the user. Once this resistance has been entered, any calculations or calibrations carried out will be based on the known values of the bridge resistors as well as the resistances of all of the cables.
In most cases this will be negligible except if long cables are used.3499class="post-3499 post type-post status-publish format-standard hentry category-p8000 tag-amplifier-gain tag-bridge-factor tag-calibration tag-excitation tag-strain-gage tag-strain-gauge tag-wheatstone-bridge"
The number of active arms in a strain gauge Wheatstone bridge is known as the bridge factor.
As a simple guide when selecting bridge factors the following rules apply; Continue reading How should the bridge factor be selected when using strain gauges?3242class="post-3242 post type-post status-publish format-video hentry category-p8000 category-tutorial category-video tag-calibrate tag-calibration tag-measurement tag-prosig tag-strain tag-strain-gauge tag-test tag-video post_format-post-format-video"
James Wren (Prosig UK) steps through how to calibrate a strain gauge for use with a Prosig P8000 system.
