NYRD 705 Guided Wave Radar Level Transmitter For Liquid In High Temperature And High Pressure Environment
Working principle of NYRD 705 Guided Wave Radar Level Transmitter For Liquid In High Temperature And High Pressure Environment
The anti-corrosive and strong microwave pulse emitted by the guided laser wave radar propagates along the detection component (steel cable or steel rod), and encounters the tested media. According 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 substances.
Input processing
Guided wave radar equipment is a measuring instrument focus on the principle of time travel. The radar tool wave runs at the speed of light, and the proceeding time can be converted into purpose level signal by electronic acceeories and components. The probe emits highly-frequency pulse & solid 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, which will automatically adapt the meter to the measuring conditions, corresponding to 4-20mA output.
Design features of NYRD 705 Guided Wave Radar Level Transmitter For Liquid In High Temperature And High Pressure Environment
◎Guided wave radar object level meter is suitable to advanced microwave processing technology and unique Echo Discovery Echo processing technology, contacting measurement, high-accuracy measurement, more accurate measurement. cuttentluy, 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 kinds. Such as: high temperature, highly-pressured and low dielectric constant medium.
◎Pulse working mode, low emission power, can be put in a variety of corrosive, non-metal containers, no harm to human body and the environment.
