The torque sensor calibration device is 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. Torque sensors are the detection of torsional torque sensing on various rotating or non-rotating mechanical components. ATO torque sensors convert physical changes in torque into precise electrical signals. It can be used in the manufacture of viscometers and electric (pneumatic, hydraulic) torque wrenches, with the advantages of high precision, fast frequency response, good reliability and long life.

Economy linear stepper motor is a stepper motor with lead screw, this stepper motor can be used in many high-precision requirements including precision calibration, precision fluid measurement, and precise positional movement, it can directly move linearly, which can make the machine miniaturized. The step size of the linear stepper motor is determined by the step angle of the motor and the pitch of the internally threaded nut and the lead screw. In order to ensure high working efficiency, there must be a certain degree of freedom between the rotor and the lead screw, which requires a certain gap between the two, which is about 0.03 to 0.08 mm backlash.

HMI, short for human machine interface, is a medium for interaction and information exchange between systems and users, which realizes the conversion between the internal form of information and the form acceptable to humans. Human-machine interfaces exist in all fields that participate in the exchange of human-machine information. So, how do HMI and PLC control VFD?

Variable frequency drive (VFD) is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. The variable frequency drive is mainly composed of rectification, filtering, inverter, braking unit, driving unit, detection unit and micro-processing unit. It adjusts the voltage and frequency of the output power supply by switching on and off the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the VFD has many protection functions, such as overcurrent, overvoltage and overload protection, etc. Now, we will talk about ATO VFD analog output setting and wiring.

A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis. PLCs were first developed in the automobile manufacturing industry to provide flexible, rugged and easily programmable controllers to replace hard-wired relay logic systems. In this article, we will introduce the counter function of PLC.

A stepper motor is a motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. Each time a pulse signal is an input, the rotor rotates an angle or moves forward one step, the angular displacement or linear displacement it outputs is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. Therefore, the ATO stepper motor is also called a pulse motor.

Do garage door openers have power? Insert a light into the socket. If the light does not come on, check the fuse box or circuit breaker. Are all doors unlocked? Re-read the installation instructions warnings. Is there ice or snow under the door? The door may have frozen to the ground. Clear obstacles. The garage door spring may have broken. Ask a qualified person to replace it.

An automatic transfer switch (ATS) is a device that automatically transfers a power supply from its primary source to a backup source when it senses a failure or outage in the primary source. When a failure occurs in a primary power system, the ATS invokes a standby power source, such as an uninterruptable power supply. An ATS can also start up more long-term backup power systems, such as local diesel generators, to run electric equipment until utility power is restored.

CNC router machine is an automatic processing equipment developed on the basis of general milling machines. The processing technology of the two is basically the same, and the structure is also somewhat similar. CNC milling machines are divided into two categories: without tool magazine and with tool magazine. Among them, the CNC milling machine with a tool magazine is also called a machining center.

The transmitter is a device that converts physical measurement signals or ordinary electrical signals into standard electrical signals (4~20mA, 0~20mA, 1~5V, 0~ 10V, etc.) output or can be output by communication protocol (CANBUS, MODBUS, PROFIBUS, etc.) ATO offers high-performance current transmitters, level transmitters, voltage transmitters, temperature transmitters, load cell transmitters, pressure transmitters, temperature and humidity transmitters, and PH transmitters.

The ATS, or automatic transfer switches, are basically the go-between utility power and generator power. There is a common load fed from the transfer switch usually to all your emergency panels. During a test or an actual power failure, there is a time delay before the ATS sends a signal to your generator, starting it. When the voltage and frequency of your generator is acceptable by the voltage sensing network, it sends a signal over to the mechanism. It will open up normal power and then close the generator. Now you're online and everything is stable at this point. When normal power, or utility comes back online there is a time delay preventing the generator from switching back- just in case normal power is unstable for a while.

Photoelectric sensor is controlled by converting changes in light intensity into changes in electrical signals. It is generally composed of three parts, which is divided into transmitter, receiver and detection circuit. The transmitter is aimed at the target and emits a light beam, which generally originates from semiconductor light sources, light emitting diodes (LEDs) and laser diodes. The beam is fired uninterrupted, or the pulse width is changed. The receiver consists of photodiodes or phototransistors. In front of the receiver, optical elements such as lenses and apertures are installed. Behind it is the detection circuit, which filters out the valid signal and applies it. The through beam type is that the transmitting end emits red light or infrared light, and the receiving end receives it.

Blowers are equipment or devices which increase the velocity of air or gas when passed through equipped impellers. They are mainly used for flow of air/gas required for exhausting, aspirating, cooling, ventilating, conveying etc. Air blower machines are a simple and effective electrical device used in homes and industries to blow away dust from every nook and corner. For gadgets and electronics that have delicate parts that cannot be cleaned with a cloth, this is when you need air blowers to remove dust with its continuous air pressure. This durable and efficient machine saves a good amount of time and effort consumed in cleaning and dusting tasks.

Mechanical vibration and noise are key factors when designing a brushless DC motor. Uncontrolled noise and vibration often cause rapid system degradation, affect efficiency, and adversely affect wear on this control system. This is especially true of sensitive medical equipment, robotics, commercial systems, and handheld devices. Noise and vibration can have a significant impact on system performance, reliability, and operating costs. For handheld devices, vibration can be transferred to the user, causing safety concerns and pressure injuries. Whether in a hospital, laboratory or office, excessive noise from motors running around people can be a health hazard.

With the development of laser technology, laser sensor has become a new type of measuring instrument. It consists of a laser, a laser detector and a measuring circuit. Its advantages are fast speed, high precision, large range, strong anti-light and electrical interference ability, etc. And it can realize non-contact long-distance measurement. It has a wide range of applications in industrial fields.

A common feature of linear DC power supply is that its power device regulator tube works in the linear region, and the output is stabilized by the voltage drop between the regulator tubes. Due to the large static loss of the adjustment tube, a large radiator needs to be installed to dissipate it. Because the transformer works on the power frequency (50Hz), the weight is large. The advantages of this type of power supply are high stability, small ripple, high reliability and easy to make multiple channels.

The brushless DC vibration motor consists of a motor body and a driver and is a typical mechanization product. The star winding of the motor is mostly made into a three-phase symmetrical star connection, which is very similar to the three-phase asynchronous motor. A magnetized permanent magnet is attached to the rotor of the motor. In order to detect the polarity of the motor rotor, a position sensor is installed in the motor. The driver consists of power electronic devices and integrated circuits.

VFD is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit and micro-processing unit. The VFD adjusts the voltage and frequency of the output power supply by turning on and off the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the inverter has many protection functions. Such as overcurrent, overvoltage, overload protection and so on. VFD is frequently used for speed regulation of AC motors or reducing the impact on the power grid on start-up.

The stability and reliability of power supply are related to the lifeblood of patients. Advanced equipment also poses challenges to power supply. During the use of medical equipment, there will be problems such as inability to work under DC and AC, electrical failure, inability to start, and output. Alarm failure, leakage, burns, button failure and other phenomena caused by equipment also occur frequently. Therefore, in this case, a special voltage regulator for medical equipment is generally used to maintain the stability of the output voltage. However, as long as it is a voltage stabilizer, it can be regarded as a special voltage stabilizer for medical equipment, but a voltage stabilizer that meets the requirements of medical equipment is a high-quality voltage stabilizer among the voltage stabilizers.

Photoelectric sensor is a switch based on the photoelectric effect, which produces a photoelectric effect after being irradiated by visible light and converts the light signal into an electrical signal for output. It converts luminous flux into electricity. In addition to measuring light intensity, it can also measure various physical quantities such as size, displacement, speed, temperature, etc. by light transmission, occlusion, reflection and interference, so it is an important sensitive device with a wide range of applications. There is no direct contact with the measured object during photoelectric measurement, and the quality of the beam is approximately zero. There is no friction in the measurement and almost no pressure is applied to the measured object.
