NYRD 702 Guided Wave Radar Level Transmitter 6m Contactable High
Accuracy
Working principle of NYRD 702 Guided Wave Radar Level Transmitter
6m Contactable High Accuracy
The high-frequency microwave pulse emitted by the guided wave radar
propagates along the detection component (steel cable orrod), and
encounters the measured medium. Beacause of 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 ratio to the distance
of the measured medium certainly.
Input process
Guided wave radar is a measuring tool based on the principle of
time travel. The radar wave runs at the speed of light, and the
running time can be converted into object level signal by
electronic components. The probe emits high frequency pulse and
propagates along the cable or rod probe.
Output process
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 environment,
corresponding to 4-20mA output.
Design features of NYRD 702 Guided Wave Radar Level Transmitter 6m Contactable High
Accuracy
◎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. At the same time, guided wave radar is not
affected by external environment such as medium temperature and
adhesion.
◎The 70X series guided wave radar object level meter is suitable
for various complex working conditions and applications due to the
various process connection modes and detection module types. Such
as: high temperature, high pressure and low dielectric constant
medium.
◎Pulse working mode, low emission power, can be installed in a
variety of metal, non-metal containers, no harm to human body and
the environment.
