How it works in two common tension sensors

What is the intermediary of the tension sensor? Do you know? It is an elastomer, which is affected by external forces, and prevents it from changing, and then converts it into a corresponding electrical signal, thereby achieving a series of subsequent operations. When the elastomer deforms, the resistance strain gauges also change together.

Today, the small series of pull sensor manufacturers introduce two kinds of commonly used, let’s take a look at it.

(1) Resistance strain sensor

The strain gauge in the tension sensor has the strain effect of the metal, and under the influence of the external force, some mechanical deformation occurs, so that the resistance value changes accordingly. Resistance strain gauges are generally divided into two major categories of metal and semiconductor. Metal strain gauges can be divided into wire type, foil type and film type. The characteristics of semiconductor strain gauges are high sensitivity, small lateral effects, etc...

(2) Resistance strain vibration sensor

Let's first take a look at its principle: every point of vibration measurement requires a small instrument, and its interior must have a "mass elastic system." When measuring vibration, we must fix the object on the instrument. When vibration occurs during use, the strain gauge accelerometer will combine well with the principle of inertial force of the system and play a good application in practical test work.

The above is a brief introduction to the principle of two types of tension sensors. For those who want to know more about the related knowledge, we can pay more attention to our ocean sensing.
