Medium Contacting Type Guided Wave Radar Level Transmitter For Dielectric Constant

High Accuracy Guided Wave Radar Level Meter Medium Contacting Type Suitable For Dielectric Constant

High Temperature And High Pressure Resistance Guided Wave Radar Level Meter Operating Principle

The high frequency microwave pulse sent by the guided wave radar transmits along the detection component (steel cable or steel rod). When the wave encounters the measured medium, due to the sudden change of the dielectric constant, some of the wave pulse will be reflected immediately back to transmitter. The time interval between the transmitted pulse and the reflected pulse is proportional to the distance of the measured medium.

input

Guided wave radar is a measuring instrument based on the principle of time travel. The radar wave runs at the speed of light, and the running time can be converted into a level signal through electronic components. The probe sends out high-frequency pulse and propagates along the cable or rod probe. When the pulse meets the material surface, it is reflected back and received by the receiver in the instrument, and the distance signal is converted into the material level signal.

The reflected pulse signal is transmitted to the electronic circuit of the instrument along the cable or rod probe, and the microprocessor processes the signal to identify the echo generated by the microwave pulse on the material surface. Correct echo signal recognition is completed by pulse software. The distance D from the material surface is proportional to the time travel T of the pulse.

output

Set by inputting empty tank height E (=zero point), full tank height F (=full range) and some application parameters. The application parameters will automatically adapt the instrument to the measurement environment, corresponding to 4-20mA output.

Guided Wave Radar Level Meter Product Feature

The guided wave radar level meter adopts advanced microwave processing technology and unique Echo Discovery echo processing technology. With contact measurement, the measurement accuracy is high and the measurement is more accurate. At the same time, guided wave radar resists adhesion and is not affected by the external environment such as medium temperature and adhesion.

A variety of process connection modes and types of detection components make the 70X series guided wave radar level meter suitable for various complex working conditions and applications. For example:; High temperature, high pressure and low dielectric constant media.

It adopts pulse working mode, with extremely low emission power, and can be installed in various metal and non-metallic containers, without harm to human body and the environment.
