Characteristics and Working Principle of IGBT27 July 2020
IGBT, Insulated Gate Bipolar Transistor, is a composite fully controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and IGFET, (Insulated Gate Field Effect Transistor). It has the advantages of both the high input impedance of MOSFET and the low on-voltage drop of GTR.
What are Weight Sensors?27 July 2020
A weight Sensor is a device that converts the quality signal into a measurable electrical signal output. When using the sensor, we must first consider the actual working environment, which is very important for the correct selection of the weight sensor. Besides, it's also related to whether the sensor can work normally, its safety and service life, and even the reliability and safety of the entire weighing instrument.
Working Principle and Development of Magnetic Sensors24 July 2020
A magnetic sensor converts changes in the magnetic properties of sensitive components caused by magnetic fields, currents, stresses, strains, temperatures, light, etc. into electrical signals, and detects devices of corresponding physical quantities in various ways.
Utmel Customer Rating Standard, Rights and Interests24 July 2020
In order to improve the service quality, and protect the rights and interests of customers actively cooperating with us, Utmel plans to divide our customers into two categories: cooperative customers and potential customers.
What is an Inductive Sensor?24 July 2020
An inductive sensor is a device to realize non-electric measurement by using the change of coil self-inductance or mutual inductance. Using inductive sensors, displacement, pressure, vibration, strain, flow and other parameters can be measured. It has a series of advantages such as simple structure, high sensitivity, large output power, small output impedance, strong anti-interference ability, and high measurement accuracy, so it is widely used in the electromechanical control system.
50 World Famous Sensor Manufacturing Companies24 July 2020
In recent years, the world sensor market has been developing stably, and companies all over the world are racing to accelerate the development and industrialization of sensors. Eastern Europe, Asia Pacific and Canada have become the fastest-growing regions in the sensor market, while the United States, Germany, and Japan still occupy the largest sensor market. Here we’re going to introduce the top 50 well-known sensor manufacturing companies in Europe, North America and Asia.
What is a Capacitive Sensor?23 July 2020
Capacitive sensors use various types of capacitors as sensing elements. It is a conversion device that converts the measured physical or mechanical quantities into changes in capacitance which is actually a capacitor with variable parameters. Capacitive sensors are widely used for measurement of displacement, angle, vibration, speed, pressure, composition analysis, medium characteristics, etc.
An Overview of Digital Signal Processor23 July 2020
A digital signal processor (DSP) is a processor composed of large-scale integrated circuit chips to complete digital signal processing tasks. Digital signal processing is the theory and technology of representing and digitally processing signals. Digital signal processing and analog signal processing are a subset of signal processing.
Introduction to Flash Memory23 July 2020
Flash memory is a non-volatile computer memory storage medium that allows multiple erases or writes during operation. This technology is mainly used for general data storage, as well as the exchange and transmission of data between computers and other digital products, such as memory cards and USB flash drives.
What is a Fiber Optic Sensor?23 July 2020
Fiber optic sensor is a sensor that converts the state of the measured object into a measurable optical signal. The fiber optic sensor is to send the light beam incident from the light source to the modulator through the optical fiber, and interact with the external measured parameters in the modulator so that the optical properties of the light such as light intensity, wavelength, frequency, phase, polarization state, etc. will be changed.
Types and Application of Position Sensors23 July 2020
A position sensor is a sensor that can sense the position of the measured object and convert it into a usable output signal. There are mainly two types of position sensors: the contact type and proximity type. They’re usually applied in brushless DC motors or as Crankshaft and Camshaft position sensors in automobiles.
Basic Introduction to RF Connector22 July 2020
The RF connector is a component that connects to the coaxial cable, microstrip line or other RF transmission line to realize the electrical connection and separation of the transmission line, or to transfer different types of transmission lines. It belongs to the electromechanical integration product and acts as a bridge.
