Product Introduction
Guided wave radar is measuring instrument based on the principle of time travel, the radar waves travel at the speed of light, the running time can be through the electronic components are converted into level signals. Probe a high frequency pulse and along the cable or rod probe propagation, when pulse meets the material surface is reflected back by the receiver instrument within the receiving and the distance signal into a signal.
Radar Level Measurement are applied in kind of vessels, storage tanks etc. that experience various processes and complicated conditions, and used in the external measurements that cannot be affected following by the change of physical property of the measured medium. It adopts two-wire system technology and is applicable to explosion-proof locations.
The maximum measured distance of the Non-contact and continuous measurement pulse-typed level measurement is 70m.
Characteristics
Ø Radar level meter adopts a recommended industry emission frequency of 26GHz, so it has beam
angle is small, concentrated energy, has stronger anti-interference ability and greatly improves the
precision and reliability of measurement.
Ø Small antenna size, easy to install and dustproof cover antenna protection device.
Ø Light weight about 1KG, easy to install.
Ø The measurement range of up to 70 meters, covering a large reservoir water level measurement.
Ø With a variety of output circuit interface and data acquisition system.
The pulse working mode, radar level meter transmit power is very low, no harm to human body and environment.
