Brief introduction

The DRD6G series sensor is an advanced radar based level measuring instrument that measures a distance of 35 meters and can be used for level measurement of storage tanks, intermediate buffer tanks, or process containers. It outputs a 4-20mA superimposed HART signal.

2、 Principle

Microwave pulses are generated by electronic units and transmitted and received through an antenna system. Radar waves travel at the speed of light, and their travel time can be converted into level signals through electronic components. A special time extension method ensures stable and accurate measurements in a very short period of time. Even in complex working conditions where there are false echoes, new microprocessing techniques and tuning software can accurately identify the echoes of the material level.

input

The antenna receives reflected microwave pulses and transmits them to the electronic circuit. The microprocessor processes this signal and identifies the echoes generated by the micro pulses on the surface of the material. The correct recognition of echo signals is completed by intelligent software, with an accuracy of up to millimeter level. The distance D from the surface of the material is proportional to the time travel T of the pulse: D=CxT/2 (where C is the speed of light and the distance E from the empty tank is known, then the material level is L=E-D)

output

By inputting the empty tank height E (=zero), full tank height F (=full range), and some application parameters to set, the application parameters will automatically adapt the instrument to the measurement environment. Corresponding to 4-20mA output
