With the rapid development of the Internet, the demand for network bandwidth by network users is increasing. In order to meet the needs of the market, the backbone of the communication network has undergone tremendous changes, and the traditional access network, which has been changing little, has become a bottleneck in the entire network, and various new broadband access techn...

The structure of the fiber Bragg grating sensing system is analyzed. The functions of three different light source LEDs, LDs and erbium-doped light sources used in the fiber Bragg grating sensing system are analyzed. The operating principle of the FBG sensor and various temperature and stress are described. The difference measurement method describes several commonly used signa...

Fiber lasers are gradually replacing the leading positions of traditional lasers in laser marking, laser welding, laser cutting and other fields.

The electrical components that the pressure transmitter feels pressure are generally resistance strain gauges, which are sensitive devices that convert the pressure on the device under test into an electrical signal. The most widely used resistance strain gauges are metal resistance strain gauges and semiconductor strain gauges. The metal resistance strain gauge has two kinds o...

Correcting humidity is much more difficult than correcting the temperature. Temperature calibration often uses a standard thermometer as a standard, and the calibration standard of humidity is difficult to achieve. Dry and wet bulb thermometers and some common pointer hygrometers cannot be used for calibration, and accuracy cannot be guaranteed because of their requirements. Th...

Pressure sensors are mainly used in: supercharger cylinders, superchargers, gas-liquid booster cylinders, gas-liquid boosters, presses, compressors, air-conditioning refrigeration equipment and other fields.
