Torque sensors, also known as torque meters, are divided into two categories: dynamic and static. Dynamic torque sensors can also be called torque sensors, torque speed sensors, non-contact torque sensors, and rotational torque sensors, etc. Today we will introduce two types of torque sensor. We hope that after reading this article, you can have a better understanding about a torque sensor.
Computer Numerical Control (CNC) routers are a class of machine shop equipment used to remove material from specific locations on wood or metal. Since each material has different advantages and disadvantages, there are different types of CNC milling machines. Computer numerical control refers to computer programming used to control and program routers. CNC routers are used to create patterns or cuts as needed. Industrial CNC routers used in factory settings are much more expensive than hobbyist models. CNC routers are attached to a table and programmed to remove material in a specific pattern or shape from a piece of wood or metal. The engraving machine is usually connected to a three-speed or four-speed motor system.
The limit switch is a commonly used small current master electrical appliance. It utilizes the collision of the moving parts of the production machinery to make or break the control circuit to achieve certain control purposes. Usually, this ATO limit switch is used to limit the position or stroke of mechanical movement, so that the moving machinery can automatically stop, reverse movement, variable speed movement or automatic round-trip movement according to a certain position or stroke.
A sound level meter is a basic noise measuring instrument, which is an electronic instrument. But it is different from objective electronic instruments such as voltmeters. When converting an acoustic signal into an electrical signal, it can simulate the time characteristic of the human ear's response speed to the sound wave; the frequency characteristic with different sensitivity to high and low frequencies and the intensity characteristic of changing the frequency characteristic at different loudness. A sound level meter is a subjective electronic instrument.
Soft starter is an AC motor control device that combines soft start, soft stop, energy saving and multi-function protection. It can be used in place of motor starters to reduce the inrush current surge caused by large loads. So how does a soft starter start and stop a motor with a bypass contactor?
Data transfer unit is suitable for many and scattered and complicated geographical environments. It can be connected to data terminals such as PLC, RTU, rain gauge, liquid level gauge, etc. Data transfer unit is widely used in power, environmental protection, LED information release, logistics, hydrology, meteorology and other industries. In the follow, the article will introduce remote transmission of data transfer unit.
This is because the structure of the inverter is AC-DC-AC. Whether single-phase 220V or three-phase 380V, the input AC power must first pass through a three phase rectifier bridge or a single-phase rectifier bridge to convert the AC power into DC power, and then use the point The capacitor filter is removed, and it becomes a DC power supply with relatively flat ripples. Next, the three-phase bridge-type urinal controlled by the chip converts the DC power supply into a three-phase AC power supply whose frequency and voltage can be controlled arbitrarily.
A pressure sensor is a device that can sense the pressure signal and convert the pressure signal into a usable output electrical signal according to a certain law. It usually consists of a pressure-sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors. ATO pressure sensor is the most commonly used sensor in the industry. It is widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electricity, ships, machine tools, pipeline and many other industries.
A Digital counter is an LED control instrument, which can be used for distance measurement, packaging counting and position control. The input signal can be various waveform pulse signals and sensor signals. The input signal can be various waveform pulses and sensor signals, such as grating, proximity sensor, photoelectric sensor, contact switch, encoder, etc. (NPN, PNP). The digital counter can be directly connected to the computer and PLC. It is widely used in food, machinery, packaging and other industries.
VFD is generally a power control device that converts a power frequency power supply into another frequency by using the on-off function of power semiconductor devices. The main circuit of the variable frequency drive can be roughly divided into two categories: the voltage type is a frequency converter that converts the DC of the voltage source into an AC, the filter of the DC circuit is a capacitor; the current type is a frequency converter that converts the DC of the current source into an AC, its DC loop filter is inductance.The following ATO will introduce you how to set 120V to 220V VFD panel
The automatic holding circuit is often used in various electrical cabinets and is a simple logic circuit. Of course, this simple logic circuit can be built in a large number of PLCs, it is the basis of PLC logic instructions.
Data transfer unit is abbreviated as DTU, is a wireless data acquisition device specially used to convert serial port data to IP data or convert IP data to serial port data. It is transmitted through a wireless communication network. Today we are going to carry ou wireless control, between computer and varible frequency drive via to different model of DTU. This is varible frequency drive.
Three-phase unbalance refers to the inconsistency of the three-phase current (or voltage) amplitudes in the power system, and the amplitude difference exceeds the specified range. Due to the unbalanced load added by each phase power supply, it belongs to the fundamental wave load configuration problem. The occurrence of three-phase unbalance is related to the user's load characteristics, as well as the planning and load distribution of the power system. This article will introduce the method to solve the three-phase unbalance.
A laser machine is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". This article will introduce the structure of laser machine.
In addition to panel control and terminal control, we can also use the RS485 interface (Modbus RTU protocol) for remote control of ATO’s variable frequency drives. RS485 interface is quite useful for the centralized control and monitoring of equipment. This type of control plays an indispensable part in automatic industrial control. That's why we write this blog to illustrate how we can use the Modbus RTU protocol to control the VFD.
Can a three-phase 220V-240V motor work with a single-phase 220V supply? ATO single-phase VFD can do it. It can convert 1-phase 220V-240V into 3-phase to supply power to a three-phase motor, and can also reduce the inrush current when the motor starts.
