A sensor is a detection device. The sensor can sense the measured information, and can transform the sensed information into electrical signals or output other required information forms according to certain rules. In this way, sensors meet the requirements of information transmission, processing, storage, display, recording and control.

The characteristics of the sensor include: miniaturization, digitization, intelligence, multi-function, systematization and networking. It is the first part to realize automatic detection and automatic control. The existence and development of sensors allow objects to have senses such as touch, taste, and smell, and make objects slowly become alive.

A vacuum cleaner is a device that causes suction in order to remove dirt from floors and other surfaces. The dirt is collected by either a dust bag or a cyclone for later disposal. We've heard of workers on the factory floor dying of pneumoconiosis, and this is a reality. The harsh production workshop environment has done great harm to people's health. As events revealed, improving the environment of production workshop area has become an important task of enterprise. Industrial vacuum cleaners can handle several hundred litres of dust. However, it will generate huge noise in use. This article will introduce several methods to reduce the noise of industrial vacuum cleaner.

A PLC takes in inputs, whether from automated data capture points or from human input points such as switches or buttons. Based on its programming, the PLC then decides whether or not to change the output. A PLC's outputs can control a huge variety of equipment, including motors, solenoid valves, lights, switchgear, safety shut-offs and many others.

A load cell, also known as a load or force transducer, is a sensor that measures applied forces. Load cells are capable of measuring both tension (force required to pull something) and compression (force required to push something). In order to measure these forces, the sensor creates an electrical output that changes depending on the amount of resistance being applied.

Programmable relay stores some typical relay logic control program in internal memory in advance and realize some simple logic control and sequence control function by the user program combination and calls. The user program uses the ladder diagram or functional diagram language through panel, intuitive and easy to understand. The switching signal input by the button, switch etc.

A load cell is a force transducer. It converts a force such as tension, compression, pressure, or torque into an electrical signal that can be measured and standardized. As the force applied to the load cell increases, the electrical signal changes proportionally. We covered How to use PLC to monitor the data of load cell transmitter in our previous blog. Today we'll show you how to use HMI to display the data of load cell in real time.

A load cell is a force transducer. It converts a force such as tension, compression, pressure, or torque into an electrical signal that can be measured and standardized. As the force applied to the load cell increases, the electrical signal changes proportionally. The most common types of load cell used are strain gauges, pneumatic, and hydraulic.

In the automated production process of industries such as food and beverages, daily chemicals, medicine, semiconductors, etc., in order to ensure the consistency of product quality, the era of direct manual monitoring and intervention in the production process has gone. Liquid level measurement and monitoring are playing an increasingly important role. It can be said that the measurement and monitoring of the liquid level directly affects the quality of the product, and even whether the production process can be carried out smoothly.

A three phase converter is needed when the "phase" required does not match the "phase" available. In other words, the equipment needs three phase power and only single phase power is available. Phase converters operate by converting single phase power into three phase power. They can also provide split phase voltages from the three phase power source. A three phase converter is used to allow operation of three phase equipment when single phase electrical services are the only power available or vice versa. The majority of the time phase converters are utilized to produce three phase power from single phase power sources as utility companies will associate higher fees for three phase electrical services due to the extra transformers, cabling, and metering required. In this article, we will introduce how to convert single phase to three phase converter.

The working principle of the constant pressure water pump is as follows:

1. The VFD drives the water pump, and the pressure sensor/transmitter feeds back the pressure signal to the VFD to form a closed loop system.
2. When the water pipe pressure is less than the set value, the VFD wakes up and starts pumping water.
3. When the pressure does not reach the set target, the operating frequency will continue to increase to the rated frequency of the pump.
4. When the pressure is greater than the set pressure, the operating frequency will decrease.
5. When the pressure is greater than the sleep pressure, the frequency decreases to the sleep frequency for a period of time, and then stops pumping water.
6. When the pressure is lower than the wake-up pressure, the pump starts to run again.

We all know vertical centrifugal pumps and horizontal centrifugal pumps, both of which are centrifugal pumps. It can be used in everyone's daily life. So what is the difference between these two pumps? And what are the differences? For this issue, ATO.com will give you a brief explanation so that you can have a more detailed understanding of these two pumps.

Diaphragm pump is a new type of mechanical transportation equipment, which can be used for all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids. Diaphragm pumps are divided into pneumatic diaphragm pumps and electric diaphragm pumps, and their materials are engineering plastics, aluminum alloys, stainless steel, cast iron, etc.

An electric actuator is a drive device that provides linear or rotary motion. It uses certain driving energy and works under the action of a certain control signal.

Limit switches are used to control the travel and limit protection of mechanical equipment. In actual production, the travel limit switch is installed in a pre-arranged position. When the module installed on the moving parts of the production machinery hits the travel switch, the contacts of the travel limit switch act to realize the switching of the circuit. Therefore, the limit switch is an electrical appliance that switches the circuit according to the travel position of the moving part, and its working principle is similar to that of a button. Limit switches are widely used in various machine tools and hoisting machinery to control their travel and perform terminal limit protection. In the control circuit of the elevator, the travel limit switch is also used to control the speed of opening and closing the car door, the limit of automatic door opening and closing, and the upper and lower limit protection of the car.

An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators.

The use of air compressors is very extensive. It can be used in instrument control and automation devices, such as tool change in machining centers.
