GCRD6X series guided wave radar level gauge

Working principle	Guided wave radar is a measuring instrument based on the principle of time travel. Radar waves travel at the speed of light, and the travel time can be converted through electronic components
	Replace with level signal. The probe emits high-frequency pulses and propagates along the cable probe. When the pulse encounters the surface of the material, it is reflected back into the instrument
	The receiver receives and converts the distance signal into a level signal.RD6XThe series of radar level gauges adopts special correlation demodulation technology,
	It can accurately identify the time interval between the transmitted pulse and the received pulse, thereby further calculating the distance between the antenna and the surface of the measured medium.

Product Features	The radar level gauge adopts a new generation of processing technology and has the following advantages:
	1. Compact contact sensors with high precision and accuracy.
	2. The measurement effect is better for materials such as powder and particles. The measurement method will not be affected by fluctuations in pneumatic filling and temperature
	BornThe impact of a large amount of dust, filling noise, or airflow.
	3Energy concentration provides greater flexibility for the installation location of radar. Has stronger anti-interference ability, greatly improving measureMeasurement accuracy and stability.
	4. The antenna size is small, making it easy for radar installation on site, and it also has better adaptability for measuring small and special tanks.
	5. The measurement blind spot is small, which maximizes the measurement range of the radar.
	6. With shorter wavelength, it can penetrate into foam and neutralize serious condensate deposition, and is suitable for occasions with particularly difficult process conditions.
	7Transmitting pulse signals, the radar level gauge has extremely low transmission power and can be installed in various metal and non-metal containers, which is harmful to the human body and the environment areaNo harm caused.
	8. The signal remains stable when measuring surface fluctuations.
	9. Easy maintenance, obvious economic advantages in price, and wide applicability.
	10. The first radar in China to add LCD backlight function, making debugging more convenient under low light conditions.
	Due to the use of advanced microprocessors and unique echo processing technology, the RD6X series radar level gauge can be applied to various complex working conditions. The use of on-site adjustable display units allows customers to adjust the range, blind spots, language, damping time according to the situation, and supports functions such as full Chinese menu, waveform display, and false echo learning, which is at the forefront of domestic technology.

INSTALLATION REQUIREMENTS

• Basic requirements and instructions

Ensure that pole and cable antennas do not come into contact with obstacles throughout the entire range, so installation should avoid tank facilities as much as possible,

Such as: escalators, limit switches, heating equipment, brackets, etc. If there is a container connection in the radar installation, it is necessary to ensure that the connection is as close as possible

Short. The distance between the radar installation position and the tank wall should be greater than 300mm, and the optimal installation position for the arc top tank is between 1/2 and 1/3 of the radius.

When installing the radar, it should be kept away from the feeding port, and attention should be paid to ensuring that the microwave beam does not intersect with the feeding material flow.

During radar measurement, it is necessary to ensure that the measured medium does not enter the radar blind zone. If the on-site environment is complex, the installation position and expansion of the radar can be appropriately increased

The solution is to install a large connecting pipe diameter.

Instruments installed in explosion-proof areas must comply with the installation regulations of national explosion-proof hazardous areas. Explosion proof instruments can be installed on explosion-proof devices

In the required situation, the instrument must be grounded.
