CBRD805 anti-corrosion high-frequency radar level gauge Introduction: The radar level gauge antenna emits narrow microwave pulses, which propagate at the speed of light in space. When they encounter the surface of the measured medium, some of their energy is reflected back and received by the same antenna. The time interval between transmitting and receiving pulses is proportional to the distance from the antenna to the surface of the measured medium. Due to the high propagation speed of electromagnetic waves, it is difficult to confirm the time interval between the emitted pulse and the received pulse, which is very small (in the nanosecond range). The 26G series radar level gauge adopts a correlation solution that can identify the time interval between the transmitted pulse and the received pulse, thereby further calculating the distance from the antenna to the surface of the measured medium. characteristic: 1. Small beam angle, concentrated energy, and strong anti-interference ability; 2. The antenna size is small, making it easy to install and install antenna protective devices such as dust covers; 3. The measurement blind spot is small, and good results can also be achieved for measuring small cans; 4. Short wavelength, suitable for level measurement of small particulate matter. 5. Equipped with a microprocessor and EchoDiscovery echo processing, the radar level gauge can be applied to complex working conditions. 6. Adopting pulse working mode, the radar level gauge has low transmission power and can be installed in metal and non-metal containers without harm to human body and environment. Technical parameters: Features: Fully sealed PTFE antenna is corrosion-resistant and resistant to slight condensation. Application: Used in corrosive environments such as acid and alkali storage tanks. When installed and used on small tanks, waves smaller than 6G The beam angle determines that by installing appropriate short pipes, a small actual measurement blind spot can be obtained. Range: 10m Measurement accuracy: ±5mm Antenna structure: Fully sealed PTFE material Process temperature: (-40～130) °C Process pressure: (-0.1～0.3)MPa Frequency range: 26GHz Signal output: (4～20)mA/HART Power supply: two-wire/four wire system
