LTR800 Radar Level Meter

LTR800 26GHz Pulse Radar Level Meter

Principle

The extremely narrow microwave pulse emitted by the antenna on radar level instrument can travel at the speed of light and part of its energy, which is reflected off the surface of target medium, is received by the very same antenna. The time lapse between pulse emission and reception by the antenna is proportional to the distance between the surface of target medium and the reference point on antenna. However, due to the fact that the electromagnetic wave is transmitted at extremely high speed, which leads to the tiny time lapse (nanosecond level) and makes it difficult to be identified, LTR800 series radar level instrument have adopted a special demodulation technology, enabling itself to detect the time lapse between pulse emission and reception correctly, and eventually generate accurate measurement result

Features

 The guided wave radar level instrument, adopted 26GHz as transmitting frequency, which make this series have specialties as below:

 1. Small beam angle, which centralize energy, make LTR800 high ability of anti-jamming, hence high accuracy and reliable.

2. Small antenna size, easy to mount and easy to equip extra dust protection

3. Small blind zone, good accuracy even for small.

4. Shorter wave-length, suitable for the measurement of powder, grain and etc. 

5. The guided wave radar level instrument, with pulses as its working tool and extremely low emission power, can be mounted on various metal or nonmetal vessels, harmless towards the environment and human beings. Equipped with advanced microprocessor and unique Echo Discovery echo processing technology, the radar level instrument can be used under various hazardous process conditions.
