Microwave level sensor KLD804

for liquidsRS-485HART

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 tiHH time lapse (nanosecond level) and makes it difficult to be identified, the series of 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. Feature • Low power consumption power supply enables the equipment to operate independently in the most remote areas; • Non-contact measurement principle. Not damaged by silt accumulation or debris; • Wireless transmission, avoid the trouble of pulling cables. Install and use, remotely unattended; • High-level industrial requirements for the appearance of the iron shell. Application in hazardous areas and harsh environments; Medium: strong corrosive liquid, steam, foam Process connection: flange ≥ DN50 Antenna size: 76mm lens antenna Antenna material: PTFE Accuracy: ±1mm Center frequency: 80GHz Launch angle: 2° Power supply: two-wire /DC24V four-wire /DC12~24V four-wire /AC220V Casing: aluminum/plastic/stainless steel
