Working principle of 5m Unique Echo Discovery Guided Wave Radar
Level Transmitter High Pressure NYRD 702
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 radar equipment is a measuring instrument focus on the
principle of time travel. The radar equipment wave runs at the
speed of light, and the running time can be converted into purpose
level signal by electronic components. The probe emits
highly-frequency pulse & liquild 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 environment,
corresponding to 4-20mA output.
Design features of 5m Unique Echo Discovery Guided Wave Radar Level Transmitter High Pressure NYRD 702
◎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. At the same time, 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.
