Nomenclature of linear displacement sensors
The function of linear displacement sensor is to convert linear mechanical displacement into electrical signal. In order to achieve this effect, the variable resistance slide is usually fixed on the fixed part of the sensor, and different resistance values are measured by the displacement of the slide on the slide. The sensor rail is connected […]
Principle of load cell_ Shape structure and weight measurement form of load cell
1. What is a load cell Load cell is used to convert weight signal or pressure signal into electricity signal. 2. What is the measuring principle of load cell The load cell is composed of a metal resistance strain gauge measuring bridge, which is made of the principle that the metal resistance wire is elongated […]
The skill of choosing suitable load cell
1、 Selection of sensitivity Generally, within the linear range of the controller, the higher the expected sensitivity is, the higher the expected sensitivity is. Because only when the sensitivity is high, the output signal value matched with the measured value is relatively large, which is conducive to signal analysis. However, when the sensitivity is high, […]
Working principle analysis of dynamic torque sensor
The general contact with industrial technology may know, what is the dynamic torque sensor? But how does it work? After reading the introduction, you will have the answer in your heart! Torque sensor is a kind of precision instrument for measuring various kinds of torque, revolutions and mechanical thermal efficiency. The static torque sensor is […]
Principle and function of negative oxygen ion sensor
The negative oxygen ion in the air is formed by oxygen molecules in the air combined with free electrons, with negative charge and redundant electrons. It has the reputation of “air vitamin” and “air vitamin”. Air negative oxygen ions have the characteristics of long migration and high activity. Medical research shows that air negative oxygen […]
Four kinds of sensors commonly used in smart home
Smart home is a systematic product concept, and sensor is the “bridge” connecting traditional home equipment such as doors and windows, lighting and so on. Through a variety of sensor devices, the scene of smart home is realized, and users can really enjoy the fun of smart home. What kinds of sensors are commonly used […]
Application of temperature and humidity sensor in household air purifier
With the improvement of people’s living standards, people pay more and more attention to health, which makes the air purifier more and more popular. Accurate detection of air index is an important prerequisite for air quality control. Among them, including the most basic index — the detection of air temperature and humidity, which requires the […]
Basic knowledge of sensors
At present, human society has entered the information age, people mainly rely on the development of information resources from the acquisition, transmission and processing. The sensor is in the interface position between the research object and the test system, which is the first of the detection and control system. Therefore, sensors become the window of […]
Analysis of open loop hall scheme for Hall current sensor
Design of Hall current sensor First of all, we need to understand the concept of Hall effect: when a small current IC passes through the semiconductor perpendicular to the external magnetic field, the carrier will deflect, and an additional electric field will be generated perpendicular to the direction of current IC and magnetic field B, […]
