10.3.2 Force and torque measuring devices
Force and weight can be measured by comparison as in a lever-type balance
which is an ON/OFF system. A spring balance or load cell can be used to generate
an electrical signal that is required in most industrial applications.
Analytical or lever balance is a device that is simple and accurate, and operates
on the principle of torque comparison. Figure 10.4c shows a diagram of a balance.
