6m NYRD 704 Coaxial Connecting & Wise Guided Wave Radar Level Meter
Working principle of 30m Coaxial Connecting & Wise NYRD 704 Guided Wave Radar Level Meter In working site
The Coaxial Connecting & Wise 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 is a measuring equipment based on the principle of time travel. The radar wave runs at the speed of light, and the running time can be converted into aim level signal by electronic components. The probe emits high frequency pulse and propagates along the cable or rod probe.
Output processing
By entering empty tank height E(= zero), full tank height F(= full range) and some application parameters, the application parameters will automatically adapt the meter to the measuring conditions, corresponding to 4-20mA output.
Design features of 30m Anti-Corrtsion & PTFE NYRD 701 Guided Wave Radar Level Meter In High Temperature & Pressure
◎Guided wave radar object level meter adopts advanced microwave processing technology and unique Echo Discovery Echo processing technology, contact measurement, high measurement accuracy, more accurate measurement. Recently, 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 which is suitable for versatile complicated working conditions and applications due to the versprocess connection modes and detection module types. Such as: high temperature, highly-pressured and low dielectric constant medium.
◎Pulse working mode, low emission power, can be installed in a variety of corrosive, non-metal containers, no harm to human body and the environment.
