Diffused silicon pressure transmitters are widely used in petroleum, chemical, steel, electric power, light industry, environmental protection and other industrial fields to achieve gauge, negative or absolute pressure measurement and control of various fluid pressures. And it can be applied to a variety of harsh and hazardous environments and corrosive media.
1. During installation, the pressure sensitive component of the transmitter should be perpendicular to the direction of gravity. If the installation conditions are limited, the transmitter zero position should be adjusted to the standard value after installation.
2, the residual pressure can not be released, so the zero position of the sensor can not come down. The reason for eliminating this cause is to remove the sensor and directly check whether the zero position is normal. If the zero position is normal, replace the seal and try again.
3. The output of the pressurized transmitter does not change, and the output of the pressurized transmitter suddenly changes, and the pressure relief transmitter can't go back. The cause of this phenomenon is most likely caused by the pressure sensor seal.
4. Whether it meets the power supply requirements; there is no wiring error between the power supply and the transmitter and the load device. If there is no voltage on the transmitter terminal or the polarity is reversed, the transmitter can output no voltage signal.
5. The outer casing of the pressure sensor and transmitter should be grounded. The signal cable should not be mixed with the power cable. Strong electromagnetic interference should be avoided around the sensor and transmitter. Sensors and transmitters should be periodically verified in accordance with industry regulations during use.
6. When selecting the pressure sensor and transmitter, the user should fully understand the working conditions of the pressure measurement system, make reasonable selection according to the needs, make the system work in good condition, and reduce the project cost.
7. Transfer to the sides of the measuring diaphragm through the spacer and the filling liquid in the component. The measuring diaphragm and the electrodes on the insulating sheets on both sides each constitute a capacitor.
8. The pressure transmitter is required to be inspected once a week, once a month. It is mainly to remove the dust inside the instrument, and carefully check the electrical components. The current value of the output should be checked frequently. The pressure transmitter is weak inside. It must be separated from the outside world by strong electricity.

Pulsed Laser

The Laser is divided into continuous laser and pulse laser in operation. Pulsed laser refers to a single laser pulse width less than 0.25 seconds, every interval of a certain time to work once the laser, it has a large output power, suitable for Laser Marking, cutting, ranging and so on. Common pulsed lasers include yttrium aluminum garnet (YAG) laser, ruby laser, neodymium glass laser, as well as nitrogen molecular laser, excimer laser and so on. Q-tuning and mode-locking are the two most commonly used techniques for obtaining pulsed lasers. The pulse width of pulse laser is usually less than ess than 0.25 seconds, which performs well in the field of laser marking, laser cutting and laser ranging.

CNI researches and develops Q-switched pulsed laser. The laser head comes with cooling and precise temperature control system, and power supply comes with overcurrent and overheating protection function.
CNI lasers have narrow pulse width, high peak power, and features of stable energy, easy operation, reliable performance and long life time.
The wavelengths of CNI lasers are available from ultraviolet to infrared range:
244nm 257nm 261nm 266nm 289nm 335nm 349nm 351nm 355nm 447nm 457nm 473nm 488nm 523.5nm 526.5nm 532nm 556nm 589nm 656.5nm 660nm 671nm 786nm 905nm 914nm 946nm 1030nm 1047nm 1053nm 1064nm 1313nm 1319nm 1342nm 1573nm 3800nm 3900-4500nm 4600nm 4800nm
