Brief introduction

The HHRD series sensor is a 26G high-frequency radar level measuring instrument that outputs a 4-20mA analog signal and can measure a maximum distance of up to 70 meters. The antenna has been further optimized and processed, and the new fast microprocessor can perform higher speed signal analysis and processing, making the instrument suitable for very complex measurement conditions such as reaction vessels or solid material silos.

2、 Principle

High frequency microwave pulses emit narrow microwave pulses, which are transmitted downwards through the antenna. After the microwave contacts the surface of the measured medium, it is reflected back and then received by the antenna system, which automatically converts it into a level signal for the electronic circuit. (Due to the extremely fast propagation speed of microwaves, the time it takes for electromagnetic waves to reach the target and reflect back to the receiver is almost instantaneous.)
