GDGW51PA Radar level meter

GDGW51PA Radar level meter

Overview

GDGW51PA Radar level meter is a measuring instrument based on the principle of time travel. The radar wave runs at the speed of light. The running time can be converted into a level signal through electronic components. The probe sends out high-frequency pulses and propagates along the cable or rod probe. When the pulse meets the surface of the material, it is reflected back and received by the receiver in the instrument, and the distance signal is converted into a level signal.The reflected pulse signal is transmitted to the electronic circuit part of the instrument along the cable or rod probe. The microprocessor processes this signal to identify the echo generated by the microwave pulse on the surface of the material. The correct echo signal recognition is completed by the pulse software, and the distance D from the surface of the material is proportional to the time travel T of the pulse: D=C×T/2.

Working principle

GDGW51PA Radar level meter, the high-frequency microwave pulses emitted by the guided wave radar propagate along the detection component (steel cable or steel rod) and encounter the measured medium. Due to the sudden change of the dielectric constant, which causes reflection, 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.
