Strain Gauge Load Cell

The resistance strain gauge sensor is the sensitive component of the resistance strain gauge, and the measured amount of the measured material (such as force, displacement, etc. > is converted into an electrical signal device.Sensor of elastic element subjected to physical quantity being measured and deformation occurs, paste the resistance strain gauge on it happening in the elastic element deformation into the change of the resistance, through measuring instrument, the change is proportional to the measured quantities into and analog electrical signals and output.


Definition

The resistance strain gauge sensor is a device that converts the measured volume (such as force, displacement, etc.) into an electrical signal.


Theory

Sensor of elastic element subjected to physical quantity being measured and deformation occurs, paste the resistance strain gauge on it happening in the elastic element deformation into the change of the resistance, through measuring instrument, the change is proportional to the measured quantities into and analog electrical signals and output.


Characteristic

The measuring accuracy of the resistance strain gauge sensor is better than 0.1%, which can work long and steady in various environments.

Because its output signals are electrical signals, it is convenient to realize the digitization and automation of physical measurement.In order to achieve this, the design of elastic elements should be ensured that the parts of the resistance strain gauge are sufficiently obvious.

Elastic elements must be used with high fatigue strength and toughness good quality materials such as 35CrMnSiA, beryllium bronze, stainless steel etc.


Classification

The common resistance strain gauge sensor can be divided into measuring force, pressure, torque, load, displacement, velocity, acceleration, flow and other sensors according to different measured physical quantities.
