I. principle of weighing transducer
The weighing sensor, which is called The weighing sensor in English, is a device that converts the weight of the measured object into an electrical signal for output. The simplest and closest application to life is the electronic scale. When we step on it, we give the scale an external force. The weighing sensor senses the external force and converts it into an electrical signal and displays it on the screen. Then we know our weight. Next we will give a detailed introduction to the structure and principle of its weighing sensor. Come up quickly.
Two, weighing sensor principle - structure
The weighing sensor is mainly composed of four parts: sensing element, transforming element, measuring element and auxiliary power supply. The sensing element is used to directly sense the weight of the object under test and output other quantities related to its mass (such as elastomer in resistance strain type weighing sensor, whose mass is expressed by deformation). The transformer is used to convert the output of the sensing element into a measurable signal (e.g., the resistance strain gauge in the resistance strain gauge weighing sensor, which transforms the deformation into resistance); the measuring element is used to convert the measurable signal output from the transformer element into a signal (e.g., the bridge circuit in the resistance strain gauge weighing sensor, which converts the resistance into resistance). Converted to electrical signals; auxiliary power supply is used to provide energy sources for measuring components to output electrical signals.
Three, weighing sensor principle
Next, we take the resistance strain gauge weighing sensor as an example to talk about the principle of weighing sensor. In the resistance strain gauge weighing sensor, the sensing element is an elastomer, the transforming element is a capacitor, and the measuring element is a bridge circuit. Finally, the change of resistance is converted into an electric signal by a bridge circuit, and thus the process of converting the weight of the object into an electric signal is completed.
Four, weighing sensor principle - Application
In our real life, there are examples of gravity being converted into electrical signals that can be used to automate a situation. For example, a dynamic weighing bridge at the entrance of a highway converts the weight of the vehicle passing through it into an electrical signal. If the electrical signal indicates its overload, the traffic signal light can be controlled to be a red light, indicating that it is not allowed to enter the highway. If the signal indicates that it is not overloaded, the traffic signal light can be controlled to be a green light, indicating that it is allowed to be. Get into the freeway. This kind of dynamic weighing bridge is often located in the lane of toll station, and its weight can be converted into electrical signals to automatically calculate the amount of payment.
