Application 1: testing machine

The measurement of the force value of the testing machine is completed by the force sensor, the expander and the data processing system. It is known from the data mechanics that under the condition of small deformation, the strain ε at a certain point of an elastic element is directly proportional to the force on the elastic element, and also to the elastic deformation. Taking the sensor of S-type testing machine as an example, when the sensor is under the effect of tension, because there is a strain gauge on the surface of the elastic element, because the strain of the elastic element is in a positive proportion to the size of the external force P, the strain gauge is connected into the measuring circuit, the output voltage can be measured, and then the output force can be measured.

The commonly used sensors of the testing machine are:

Spoke sensor series

S-type tension and pressure sensor series

The different range of tension determines the different sensors used, and also determines the structure of the tension machine. Different testing machines have different requirements for the mounting hole and measuring range of the sensor. Chcontech provides various non-standard size spoke sensors to meet the production requirements of different manufacturers, which are widely praised in the industry.
