A pressure switch is an electrical contact device that drives a switch through the action of gas or liquid pressure. It is mainly composed of power or pressure sensitive components (feeling external pressure), mechanical linkage mechanism (transmitting pressure), micro switch (executed by normally open and normally closed contacts) and other parts. Understanding the working principle of the pressure switch helps us to use it better. The following will provide you with the knowledge of the working principle, application and adjustment method of the pressure switch.

In the 21st century and even in the future, it is an inevitable trend for enterprises to implement advanced automation, and instruments and meters will be indispensable for the operation of equipment. Pressure gauges refer to instruments that use elastic components as sensitive components to measure and indicate pressure higher than the environment. Since the main body is mostly made of stainless steel and has strong sealing performance, it has strong corrosion resistance, which undoubtedly expands the scope of use in the industrial field. Therefore, it is essential to understand the specific application range of the pressure gauge. Today let's learn the application and structural knowledge of pressure gauges.

Hydraulic jack is a kind of the simplest lifting equipment that lifting height is little (less than 1m). The hydraulic jack has compact structure, stable operation and self-locking effect, so it is widely used. Jacks are mainly used in factories, mines, transportation and other fields as vehicle repairs and other lifting, support and other work. Its structure is light and strong, flexible and reliable, and can be carried and operated by one person. As a tool with a wide range of uses, the hydraulic jack can only play its role better if you understand its principle. Next, let's learn how the hydraulic jack works and how to use it.

When there is a fire, the smoke will cause hypoxia of the human body. When the smoke reaches a certain concentration, the human body will have difficulty breathing due to lack of oxygen. When the smoke enters the lungs, it can cause death by suffocation due to its weakened ability to combine oxygen and carbon dioxide. When smoke enters the body through the respiratory system, it raises the awareness of respiratory diseases. To protect people's health and safety, smoke detectors were created. Smoke detector is to monitor the concentration of smoke to achieve fire prevention, it is a kind of advanced technology, stable and reliable detector and is widely used in a variety of fire alarm systems. So let's learn what smoke alarms can do.

Since GPRS DTU is mostly used in remote monitoring sites, the stability of GPRS DTU becomes very important. Many users choose GPRS DTU, and it is not enough to finish the selection work only by doing some simple tests in the early stage. If you choose an unstable GPRS DTU and apply it in large quantities, it is tantamount to planting a time bomb for your own monitoring system. So how can you test the stability of GPRS DTU comprehensively and quickly at the beginning? This has become an important topic.

Data Transfer unit is a wireless terminal device specially used to convert serial port data into IP data (or convert IP data into serial port data), and then transmit it through the wireless communication network. DTU has been widely used in electric power, environmental protection, LED information release, logistics, hydrology, meteorology and other industries. Although the applied industries are different, the applied principles are the same. Most of the DTUs are connected to industrial equipment, such as PLC, single-chip microcomputer and other automation products, and then establish a wireless communication connection with the background. With the increasing development of the Internet today, the use of DTU is becoming more and more extensive. It provides assistance for information and industrial integration of various industries and between industries.

Digital force gauges are widely used in various industries such as pharmaceuticals, cosmetics, food, packaging, automobiles, electrics, electronics, and machinery. It is an indispensable force measuring tool in product manufacturing, quality management, research and development. The digital dynamometer is based on the traditional mechanical dynamometer structure that uses knives, knife bearings, and levers as the measurement structure and is displayed by mechanical transmission. It is reformed to use sensors to convert electrical signals into electrical signals for measurement and display, so as to achieve the purpose of force measuring instruments. In structure, there are only a small number of mechanical parts in the detection part and others are composed of electronic devices. Therefore, the digital force gauge is an integrated instrument and equipment with the force-electric sensor as the core and the electrical signal measurement and display as the main body.

The photoelectric smoke detector is composed of a light source, a photoelectric element and an electronic switch. It is developed by utilizing the basic property that the smoke generated during a fire can change the propagation characteristics of light. The photoelectric smoke detector adopts a photoelectric sensor with a special structure design, which has the advantages of high sensitivity, stability and reliability, low power consumption, beautiful and durable, and easy to use. Its circuit and power supply can be self-tested, and analog alarm tests can be performed.

In order to make buildings safer and avoid the probability of fire, most people have installed smoke alarms in buildings, but many people don’t know much about smoke alarms. How can we solve the problem if it keeps beeping? Is the smoke alarm going off for no reason because formaldehyde exceeds the standard? In fact, this has nothing to do with formaldehyde, it may involve a variety of reasons.

The temperature sensor converts the relationship between various physical properties of materials and temperature into effective output signals. As the core component of the thermometer, there are many types. According to its measurement method, it can be divided into two categories: contact type and non-contact type. According to the characteristics of its material and device, it can be divided into thermal resistance type and thermocouple type. The current temperature sensor is very small, so it has great applications in many aspects of actual production, which brings a lot of convenience and practicality to our life.
