A load cell is a transducer which converts force into a measurable electrical output. Although there are many varieties of load cells, strain gauge based
The cameras send the feed to a central control center where a producer selects feeds to send to the television monitors that fans can view
An RTD is a temperature sensor which measures temperature using the principle that the resistance of a metal changes with temperature
A strain gauge is a type of electrical sensor. It's primary use is to measure force or strain. The resistance of a strain gauge changes when force is applied and this change will give a different electrical output. Strain gauges use this method to measure pressure, force, weight and tension.
