1、 Product application

The ZDW922 guided wave radar level switch series adopts microwave technology, advanced microprocessors, and unique EchoDiscovery echo processing technology, which has high sensitivity and is suitable for measuring media with small dielectric constants. The guided wave radar level switch adopts a pulse working mode, with extremely low transmission power, and can be installed in various metal and non-metal containers without harm to the human body and the environment.

2、 Principle

The guided wave radar level switch emits high-frequency microwave pulses through the detection rod. When the measured medium encounters the detection rod, the change in dielectric constant causes a change in the reflected microwave wave, which reflects the change in level. The internal CPU processor outputs it as the level switch quantity.
