NYRD803 High Accuracy 0-35m Radar Level Gauge Horn Type 6.8GHz 4-20mA Radar Level Transmitter for Unstirred Liquids
NYRD803 Radar Level Transmitter Working Principle
Input:
The antenna receives the reflected micro pulse and transmits it to the electronic circuit. The microprocessor processes the signal and identifies the echo generated by the micro pulse on the material surface. The correct echo signal recognition is completed by pulse software, and the accuracy can reach millimeter level. The distance D from the material surface is proportional to the pulse time travel T: D=C×T/2(C is the speed of light)
Since the distance E of the empty tank is known, the material level L is: L=E-D.
Output:
It is set by inputting empty tank height E (= zero point), full tank height F (= full scale) and some application parameters. The application parameters will automatically adapt the instrument to the measurement environment, corresponding to 4-20mA output.
NYRD803 Radar Level Transmitter Design Features
Various process connection modes and types of detection components can be customized according to customer requirements.
With pulse working mode, the product has extremely low emission power and can be installed in various metal and non-metal containers, without harm to human body and the environment.
