Guided Wave 4-20mA Hart Radar Solid Level Transmitter Gauge
Principle
The 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.
Features
-Small beam angle (min 5º), centralized energy and stronger antijamming capability which have significantly improved the
measurment accuracy and reliability;
-Small antenna size which facilitates installation and addition of protective devices for antenna such as a dust-proof cover;
-Smaller unmeasurable zone which can help to obtain good results for measuing small tanks;
-Shorter wavelength which is more suitable for level measurement of small particulate matters.
