The proximity sensor is a general term for sensors that detect objects without touching them instead of contact detection methods such as limit switches. The sensor converts the movement and presence information of the detected object into an electrical signal. Among the detection methods that convert the information into electrical signals, some methods utilize the eddy current generated in the metal body of the detection object due to electromagnetic induction, methods that change the capacity of the electrical signal due to the proximity of the detection object, and methods that use a sharp stone or a guide switch, etc. ATO.com will introduce the basics such as the principle of operation, types, and applications of the proximity sensors in detail in this article.

The Diaphragm valve is a diaphragm as the opening and closing parts close the flow path, cut off the fluid, and the valve body cavity and bonnet cavity separated from the stop valve. The structure of the diaphragm valve is very different from the general valve, is a new type of valve, and is a special form of stop valve, its opening and closing parts are a piece of soft material made of diaphragm, the valve body cavity and the bonnet cavity and drive parts separated, is now widely used in various fields.

The magnetic drive pump is a new type of sealless pump that uses the principle of permanent magnet transmission technology to achieve contactless transmission of torque. There is no mechanical connection between the driving shaft and the driven shaft, and no dynamic seal is required in the structure. Therefore, this type of pump has no seal and can achieve zero leakage. The magnetic drive pump is especially suitable for transporting flammable, explosive, volatile, toxic, and hazardous materials. For corrosion and precious liquids, magnetic pumps are mostly used in situations where the magnetic drive pump can only leak slightly or even without leakage, as well as in high vacuum situations where mechanical seals are difficult to handle.

The clamp meter is a combination of a current transformer and an ammeter. Usually, when measuring current with an ordinary ammeter, it is necessary to cut off the circuit to stop before the ammeter can be accessed for measurement, which is very troublesome, and sometimes the normal operation of the motor does not allow this to be done. At this time, the use of a clamp ammeter is much more convenient, you can not cut off the circuit to measure the current.

A potential transformer (PT for short, also known as Voltage Transformer, VT for short) is similar to a transformer and is an instrument used to convert voltage. A potential transformer is an indispensable electrical appliance in power transmission and power supply systems such as power plants and substations. A precision voltage transformer is an instrument used in electrical testing laboratories to expand the measurement limit and measure voltage, power, and electrical energy.

Electric ball valve is a modern control equipment, usually used for pipeline media remote opening and closing (connecting, cutting off the medium) control, but also industrial automation process control in an important pipeline pressure components, widely used in industrial automation control field. It can accurately control the opening and closing of the ball valve through the electric actuator to realize the precise adjustment of the flow and pressure of liquid, gas and corrosive media. In an electric ball valve, the ball can be rotated within the seat to control the on-off and flow of fluid. The electric actuator is connected to the ball to realize the on/off operation through the electric signal. The control system is responsible for receiving the signal and controlling the movement of the actuator to adjust the status of the valve.

Check valve refers to the opening and closing parts for the round valve and rely on their own weight and media pressure to produce action to block the medium backflow of a valve. Belong to the automatic valve category, also known as check valve, check valve, backflow valve or isolation valve. Flap movement is divided into lift and rotary type. Lift check valve and globe valve structure is similar, only the lack of valve stem to drive the valve flap. The medium from the inlet side (lower side) inflow, from the outlet side (upper side) outflow. When the inlet pressure is greater than the weight of the valve and its flow resistance and when the valve is open. Conversely, the medium backflow valve is closed.

A CNC router machine is a processing machine tool that is widely used in machine tool equipment. It can perform plane milling, plane cavity milling, outline milling, three-dimensional and more complex surface milling, and can also perform drilling, boring, thread cutting, and other holes. The powerful functions of the CNC router machine enable it to be widely used in the industrial field.

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.
