Anti-corrosion radar level gauge

1. Product overview

DPRD11 is a 26G high frequency radar type level measuring instrument, which outputs 4~20mA analog signal, and the measuring distance can reach 20 meters. The antenna is further optimized, and the new fast microprocessor can perform higher-speed signal analysis and processing, so that the instrument can be used for: very complex measurement conditions in reactors or solid silos.

2. Principle

The radar level meter antenna emits narrow microwave pulses, which are transmitted downward through the antenna. After the microwave touches the surface of the measured medium, it is reflected back, and is received by the antenna system again and transmitted to the electronic circuit part to automatically convert it into a level signal.
