KLD 26GHz Series High Frequency 4-20mA HART RS485 Modbus Radar Level Meter Powder Level Meter

KLD 26GHz Series High Frequency 4-20mA HART RS485 Modbus Radar Level Meter Powder Level Meter

This radar level meter series utilizes a 26G high-frequency radar sensor. It can measure up to 80 meters, thanks to the newly developed microprocessor that enables faster signal analysis and processing. This ensures its suitability for measuring complex environments, such as reactors and solid silos.

1. Working Principle:

The radar antenna transmits a narrow microwave pulse, which reflects back upon reaching the surface of the tested medium and is then received by the antenna system. The signals are sent to the electrical circuit and converted into level signals. Due to the rapid transmission speed of microwaves, the time taken for the transmission to the surface of the tested medium and back is nearly zero.

​

2. Technical Features:

• Small antenna size, easy to install; non-contact radar, no wear, no pollution.
• Almost no corrosion, no bubble effect; almost not affected by steam in the atmosphere, temperature and pressure changes.
• Serious dust environment has little effect on the high level meter work.
• Shorter wavelength means better reflection for inclined solid surface.
• Small beam angle and concentrated energy enhances the echo ability and avoid interference.
• Small measurement blind area means accurate measurement also for small tanks.
• High signal-to-noise ratio means good performance also even under flucturation state.
• High frequency, which is the best choice for measurement of solid and low dielectric constant medium.
