The Working Principle of 26GHz high Frequency Radar Level Transmitter

DATE: 2018-07-18
BROWSE TIMES: 20

26GHz high frequency Radar level transmitter/measurement is precise, efficient, maintenance free, reliable and easy to install. Practically all liquids, solids and semi solids can be detected with radar level transmitter, regardless of temperature and density, fluctuations.


Radar Level Transmitter using the operating mode of emission-reflection-receiving. Its antenna transmits high frequency microwaves plus, these waves is reflected by the surface of the medium and received by the antenna again. The time from transmitting to receiving is proportional to the distance of the level surface. Radar level transmitter records the time of the pulse wave passing through, while the transmitting speed of the electromagnetic wave is a constant, you can calculate the distance from the medium surface to the radar antenna, and get the level or height of the medium. 


There are two types of radar level transmitter, one is frequency modulation continuous wave(FMCW) type, and the other one is pulse wave type. For the FMCW type, power consumption is high, so it needs 4-wire system, the electronic circuit is complicated. While for the pulse wave type, the power consumption is low, it is available to use 2-wire system and power of 24VDC. With intrinsic safety, high precision, it is used more widely. Generally, radar level transmitter is suitable for variety of containers, tanks, hoppers etc. at complex process conditions. It is not effected by the measured medium's physical properties change. Two-wire technology, suitable for explosion-proof field site. The max. measuring range is up to 70M for Non-contact and continuous measurement of pulse wave type.

    It is known that intelligent radar level transmitter functions according to echo distance measurement principle, but few people know how radar level transmitter measures substance distance by electron wave. Where will radar level transmitter be used in life? Our R&D team will give you answers on its working principle in the following:Radar level transmitter emits the microwave transmitted by antenna while signal processor compares the emission signal with received signal, the measured distance is calculated. Because microwave occurs attenuation and noisy reflection, the key measurement is received and reflected echo and identified the effective echo. :High frequency radar level transmitter is converted into level signal based on specific time stretch by electronic compon...
