26G Radar Level Transmitter Sensor Gauge 4-20mA HART protocol
Product Description
The gided wave radar level transmitter,adopted 26GHz as
transmittion frequency,which make this series have specialties as
below:small beam angle,shich centralize energy,make WNKGDRD5X high
ability of anti-jamming,hence hign accuracy and reliable.Small
antenna size,easy to mount and easy to equip extra dust
protection,.Small blind zone,good accuracy even for small
vessels.Shorter wave-length,suitable for small power.
WNKGDRD55
Application:Level measurement in liquids,especially erosive
liquids, under easy process condition
WNKGDRD56
Features: Multiple patented antennas, anticoagulation,
anti-attachment, min transmitting angle: Solve the problem of large
blind zone and multiple echo that 6G radar has in small tanks.
Application:Level measurement in liquids . For example:oil tanks
WNKGDRD57Features: PTFE conic antenna, anticorrosion, anticoagulation.
Application: Measurement of strongly corrosive liquids in the food
and medical industries or health-class environment.
WNKGDRD58
Features: Multiple patented antennas, anti-dew, anti-
crystallization, anti-attachment, dustproof, centralized beam.
Solve the shortcomings of 6G radar antenna such as easy to block,
large size, large transmitting angle, incorrect measurement and
short
measuring distance, etc.
WNKGDRD59
Application:Storage/process vessels under hazardous process
condition
Measurement Range:70m
Measurement Accuracy:±15mm.
Detailed Images
PrincipleThe antenna of radar level instrument transmits a very narrow
microwave pulse which propagates at the speed of light in space.
When meeting the dielectric surface to be measured, part of its
energy is reflected and received by the same antenna. The time
interval of transmitting and receiving pulses is proportional to
the distance between antenna and dielectric surface to be measured,
and therefore the distance between antenna and dielectric surface
to be measured can be calculated.
How do we judge when selecting the right model? We need to pay
attention to two aspects: 1. Obstacle impact If the ultrasonic wave or electromagnetic wave
from the instrument touched obstacle, a disturbing wave will be
generated accordingly. In case of failure to choose other ideal
positions for installation, you could install by choosing the
instrument with small beam angle, or adopting wave guide or by-pass
pipe as well. 2. Influence of propagation medium a.Temperature b.
Pressure c.Corrosion of propagation medium d. If any stream or
powder out of propagation medium e. The issues concerning crystal
of volatile material or powder conglutination.
