The working principle of a force sensor: A Wheatstone bridge consists of four rod gauges. Because the strain gauges are firmly connected to the elastic body, they undergo the same deformation as the elastic body, and the small-volume force sensor is adjusted, resulting in a change in resistance. The Wheatstone bridge output signal provides this deformation information to calculate the force applied to the valve stem gauge. More specifically, force sensors can integrate sensors with amplification, calculation, and other physical quantities (such as temperature, pressure, angle, acceleration, vibration, etc.). Users can directly read or use force values and other physical changes via wired, wireless, or bus transmission modes to ensure the safety of mechanical equipment applications. What are the working principles and functions of a force sensor?
Force sensor working principle
Force sensors utilize most mechanical principles, including the three-part mechanical theory, hence the name "force sensor." While there are different types of force sensors, their principles are similar. Because they relate to force, force sensors are also widely used in weighing connections. Based on this solution, force sensors are used in many ground pumps and for weighing some large moving objects.
Force sensor function
In fact, this type includes more complex rod-tube and rod-beam types. Sensor elements include thin films, plastic boxes, bellows, Bourdon tubes, etc. Elastic rod elements include skeleton beams, fixed beams, irregular beams, ring beams, thin-walled cylinders, etc. They can be combined into different types according to different needs. Strain pressure sensors are mainly used to measure the dynamic or static pressure of flowing environments, such as gas or liquid pressure at the inlet and outlet, and pressure in internal combustion engine pipelines.
