The running time of the LKD800 series radar level gauge can be converted into a level signal by electronic components. A special time extension method can ensure stable and accurate measurement in a very short time. It is transmitted and received by an antenna system by transmitting extremely short microwave pulses with very low energy. LKD800 series radar level gauge can accurately analyze the echo of the material level even if the working conditions are complicated and there are false echoes. enter The antenna receives the reflected microwave pulse and transmits it to the electronic circuit, and the microprocessor processes the signal to identify the echo generated by the micro pulse on the surface of the material. The correct echo signal identification is completed by intelligent software, and the accuracy can reach millimeter level. The distance D from the material surface is proportional to the time travel T of the pulse: D=C×T/2 where C is the speed of light Since the distance E of the empty tank is known, the level L is: L=E-D output It is set by inputting the empty tank height E (= zero point), the full tank height F (= full scale) and some application parameters, and the application parameters will automatically adapt the instrument to the measurement environment. Corresponding to 4-20mA output. Application medium: LKD800 series radar level gauge is suitable for non-contact continuous measurement of the level of liquid, slurry and granular material. It is suitable for occasions with large temperature and pressure changes and the presence of inert gas and volatilization.
