Advanced Microprocessors Guided Wave Radar Level Meter For Complex Applications
Working principle of Advanced Microprocessors Guided Wave Radar Level Meter For Complex Applications
The anti-corrosive and microwave pulse emitted by the guided wave radar propagates along the detection component (steel cable or steel rod), and encounters the tested media. Due to the sudden change of the dielectric constant, it causes reflection, and a part of the pulse energy is reflected back. The time interval between the transmitted pulse and the reflected pulse is proportional to the distance of the measured medium.
Input processing
Guided wave radartool that is a measuring equiptment aimed at the relation of time travel. The 701 thread & flange Anti-Corrtsion wave guided radar wave runs at the speed of light, and the moving time can be converted into purpose level signal by electronic components. The wise anf fuctional probe emits highly-frequency pulse and propagates along the cable or rod probe.
Output processing
By entering empty position like a tank height E(= zero), full tank height F(= full range) and some application parameters, the application parameters will automatically and dy adjust the meter to the measuring environment, corresponding to 4-20mA output.
Design features of Advanced Microprocessors Guided Wave Radar Level Meter For Complex Applications
◎Guided wave radar object level meter attempts advanced microwave processing technology and unique Echo Discovery Echo processing technology, contacting measurement, highly-accurated measurement, more accurate measurement. Besides, which is guided wave radar is not affected by external environment such as medium temperature and adhesion.
◎The 70-X series guided wave radar object level meter is suitable for versatile complicated working conditions and applications due to the versprocess connection modes and detection module types. For instance: high temperature, highly-pressured and low dielectric constant medium.
◎Pulse working moder, low emission power, can be installed in a large variety of corrosive, non-metal containers and non stainless steel no harshness to human body and the surroundings around.
