Why do you need a load cell amplifier?

A load cell amplifier is a device that can increase the strength of signals coming from a load cell. Sometimes, the signals produced by the load cell can be feeble and low strength signals may not work with certain components of the measuring system like a data logger for load cells or load meter.

Why do sensors need amplifiers?

The input of sensors is characteristics of the environment for example temperature, pressure and etc. and their output is a small electric voltage or current. Since the output current or voltage is very small, it must be amplified in order to be suitable for use in electronic systems.

How does a load cell work Arduino?

A load cell is an electronic sensor for measuring weight and force. When a force is applied to it, a weak electrical signal at the millivoltage level appears on its output wires. In fact, the load cell is a transducer which converts force into measurable electrical output.

What is strain gauge load cell?

Strain gauge load cells are a type of load cell where a strain gauge assembly is positioned inside the load cell housing to convert the load acting on them into electrical signals. The weight on the load cell is measured by the voltage fluctuation caused in the strain gauge when it undergoes deformation.

What type of amplifier circuit is used in load cell?

These strain gauges are arranged in what is called a Wheatstone Bridge Amplifier Circuit (aka Load Cell Amplifier Circuit). This means that four strain gages are interconnected as a loop circuit and the measuring grid of the force being measured is aligned accordingly.
