26GHz NYRD-PB-E Flat Radar Level Meter

The flat-panel radar level meter is a 26GHz high-frequency radar level measuring instrument with a maximum measurement distance of 40 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 in some complex occasions such as steam, foam, dust, crystallization, condensation, etc..

Radar Level Meter Operating Principle

The radar level antenna emits narrow microwave pulses, which are transmitted downward through the antenna. After the pulse touches the surface of the measured medium, it is reflected back and received by the antenna system again, and the signal is transmitted to the electronic circuit part and automatically converted into a level signal (because the pulse propagation speed is extremely fast, the electromagnetic wave reaches the target and is reflected back to the receiver. The time taken is almost instantaneous).

Radar Level Meter Design Features

◎ The antenna is small in size, easy to install; non-contact radar, no wear and no pollution.

◎ Unaffected by corrosion, foam, water vapor, temperature and pressure changes.

◎ The beam angle is small and the energy is concentrated, which enhances the echo ability and helps to avoid interference.

◎ The measurement blind area is smaller, and it can also achieve good results for small tank measurement.

◎ High signal-to-noise ratio for better performance even under fluctuating conditions.

Radar Level Meter Protection Class

 

This instrument fully meets the requirements of protection class IP66/67. Figure 6:

• How to Ensure Your Installation Meets IP67 Requirements:
• Make sure the sealing head is not damaged.
• Make sure the cable is not damaged.
• Make sure that the cables used meet the electrical connection specifications. Bend the cable down before entering the electrical interface to ensure that water does not flow into the housing, see ①
• Please tighten the cable gland,see②
• Please plug the unused electrical connections with blind plugs, see ③
