What is a SAW Sensor? Types, Working and Applications29 March 2021
The SAW (Surface Acoustic Wave) sensor is a new type of micro-sensor that has developed in recent years. It is an acoustic surface wave device as a sensor element that will be measured through the acoustic surface wave device. The speed or frequency of the wave is reflected and converted into the sensor output by the electrical signal.
Applications of Sensors on CNC Machine Tools13 September 2021
With the continuous update and development of CNC machine tools and sensors, some sensors have been eliminated, such as resolvers and other sensors. Similarly, some newer sensors have also been eliminated. The constant emergence has led to the renewal and improvement of CNC machine tools.
The History of Thermometers12 August 2026
Hello everyone, I am Rose. Today I will introduce you thermometers. Thermometers are tools that can accurately judge and measure temperature and are divided into pointer thermometers and digital thermometers. According to the difference of the purpose of use, a variety of thermometers have been designed and manufactured.
Introduction to DC Amplifier07 November 2025
An amplifier that can amplify DC signals is called a DC amplifier. A DC amplifier amplifies a DC signal or an alternating signal that changes very slowly with time.
What is the Difference between an Integrated Circuit and a Chip04 August 2026
An integrated circuit (IC) is an electronic circuit whose components and interconnections are formed together on semiconductor material. A chip is a less rigid word. Depending on the speaker, it may mean the bare silicon die, the IC on that die, or the packaged device sold for assembly onto a circuit board. For precise engineering work, use wafer, die, package, and packaged IC instead of expecting the word chip to identify one manufacturing stage.
Introduction to Voltage Stabilizer03 September 2020
A voltage stabilizer is a device that stabilizes the output voltage. The voltage stabilizer is composed of a voltage stabilizer circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate to change the position of the carbon brush of the voltage stabilizer. The coil turns ratio is automatically adjusted to keep the output voltage stable.
Rheostat Basics: Types, Principle and Functions25 December 2025
A rheostat is a device that can adjust the size of the resistance and can be connected to the circuit to adjust the size of the current. A general rheostat is composed of a wire with a larger resistance and a device that can change the contact point to adjust the effective length of the resistance wire. Rheostat can limit the current and protect the circuit, and change the voltage distribution in the circuit.
Introduction to Microprocessors18 August 2020
The microprocessor is the central unit of a computer system performing arithmetic and logic operations which typically involve adding, subtracting, moving numbers from one field to another, and comparing two numbers. It's often simply referred to as a processor, a central processing unit, or a logic chip.
15 Key Elements of Diode Selection26 November 2021
Hello everyone, I am Rose. Welcome back to the new post today. Diodes are one of the most common components in our circuit boards. So, what factors should be considered when selecting models?
What is a Digital Integrated Circuit and How Do We Use It?20 October 2025
Digital integrated circuits are digital logic circuits or systems made by integrating components and wires on the same semiconductor chip. According to the number of included gate circuits or components, digital integrated circuits can be divided into Small Scale Integrated (SSI) circuits, Medium Scale Integrated(MSI) circuits, Large Scale Integration (LSI) circuits, Very Large Scale Integrated (VLSI) circuits, and Ultra Large Scale Integration (ULSI) circuits.
What is Server and Why does a Server Crash?14 September 2021
The server provides computing or application services for other clients (such as PCs, smartphones, ATMs, and other terminals or even large equipment such as train systems) in the network.
Introduction to EPROM and EEPROM08 January 2026
EPROM (Erasable Programmable Read-Only Memory) is a kind of ROM memory with erasable function and can be reprogrammed after erasing. Before writing, the contents inside must be irradiated with ultraviolet rays on the transparent window on its IC card to clear it. EEPROM (Electrically Erasable Programmable Read-Only Memory), a memory chip that does not lose data after power failure. EEPROM can erase the existing information and reprogram it on the computer or special equipment.
