Visual inspection is the use of machines to replace human eyes for measurement and judgment. Visual inspection refers to the conversion of the target being captured into image signals through machine vision products (i.e., image capture devices, divided into CMOS and CCD), which are transmitted to a dedicated image processing Read more
It takes the displacement signal of valve stem as the input feedback measurement signal, compares it with the output signal of controller as the set signal, and changes its output signal to the actuator when there is a deviation between the two, so that the actuator can act. It establishes Read more
Ultrasonic waves are mechanical waves with a vibration frequency higher than 20kHz. They have characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directionality, and can be directionally transmitted as rays. Ultrasonic waves have great penetration ability for liquids and solids, especially in solids that are not transparent Read more
Transmitters have evolved from sensors, and any sensor that can output a standard signal is called a transmitter. Standard signal refers to a signal whose form and quantity range of physical quantities comply with international standards. Due to the advantages of not being affected by inductance, capacitance, and load properties Read more
Transmitters are developed from sensors, and any sensor that can output standard signals is called a transmitter. Standard signals refer to signals whose physical quantity forms and quantity ranges meet international standards. Due to the advantages of DC signals, such as being immune to the effects of inductance, capacitance, and Read more

The reducer is an independent component consisting of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing. It is commonly used as a reduction drive between the prime mover and the working machine. It plays a role in matching speed and transmitting torque between the prime mover Read more
The liquid level sensor (static pressure level gauge/liquid level transmitter/liquid level sensor/water level sensor) is a pressure sensor dedicated to measuring liquid levels. The static pressure input type liquid level transmitter (level gauge) operates on the principle that the measured liquid’s static pressure is directly proportional to its height. Utilizing Read more
is an early electrical signal amplification device. The cathode electron emission part, control grid, acceleration grid, and anode (screen) leads enclosed in a glass container (usually a glass tube) are soldered to the tube base. The control grid is injected with an electronic modulation signal in a vacuum using an Read more
The Silk Road Economic Belt focuses on: bringing together China, Central Asia, Russia and Europe (the Baltic); linking China with the Persian Gulf and the Mediterranean Sea through Central and Western Asia; linking China with the Indian Ocean through Southeast Asia and South Asia. The 21st-Century Maritime Silk Road is Read more
