Today Load Cells (strain Gauges) - it is A Device for Measuring the Deformation

Load cells (strain gauges) are the main primary conversion device physical weight values into standard electrical signal. The signal from the secondary pickoff subsequently processed converters (light weight, a weight processor, an analog-digital converter, etc.).

Load cells (strain gauges) - it is a device for measuring the deformation of different designs based on the determination of the displacement (or displacement) of the elastic element. Sensors can measure the bias as a linear shift (in forward movement) and rotation angle (by rotating).

There are many ways to measure the strain used in accordance with the principle of transformation: the thin-film, optical polarization, optical fiber, or simply reading a line of mechanical load cell. Of electronic load cells, the most widely Thin-film sensors.

There are different types of strain gauges, depending on the application:

force measuring load cells measure force and load;

weighing load cells measure weight;

strain gauge pressure measured pressure in different environments;

accelerometers, acceleration sensors;

strain gauges movement;

strain gauge torque.

The most typical application of strain gauges are weight scales. Depending on the design of the platform used weight load cells of different types:

cantilever beam load cells or strain gauges;

s-shaped load cells;

strain gauges "Puck" or membrane-type strain gauges;

strain gauges "barrel" or column-type load cells.

Construction of strain gauges.

Thin-film strain gauges are resilient element which is fixed gage. Under the force (weight of the load), the deformation of the elastic element with strain gage. By changing the resistance of the strain gauge can calculate the degree of deformation that is proportional to the force applied to the structure.

The principle of weight measurement using strain gauges based on the weight of the weighed load balancing with the resilient force of a mechanical strain gauge and the subsequent conversion of this force into an electrical signal for subsequent processing.

Load cells are the most vulnerable components of the weighing system. During the operation on the weight load cells act: aggressive environment, impact dynamic loading, electrostatic effects (welding), vibration, etc. Therefore, during periods of maintenance before installation in equipment as well as in emergency situations, there is a need for diagnostic weight strain gauges.

Load cells - the main element of the weight and force measuring equipment with high accuracy.

Load cells - the force transducer that measures mass by converting the measured quantity (mass) to another measured quantity (output) with the influence of gravity and air buoyancy acting on the object to be weighed.

S shaped type load cells are used to make false hopper scales, crane scales, test systems, tensile testing machine, as well as modernization of mechanical scales.

Due to the high metrological characteristics of the strain gauges S shaped type are widely used in many industrial applications the weight measurement.
