KWL803 Radar Level Sensor 40m IP68

40m IP68 Industrial Radar Sensor

Description

Description

1.1 Product Overview

KWL803 radar level sensor conforms to the standard specifications outlined in national standard DB50/T 826-2017 for level meters. Its core component is designed with a fully sealed IP68 waterproofing.
The maximum measurement range of the product extends up to 40 meters, with a minimal blind spot of less than 6 cms.
Due to its higher frequency and broader bandwidth, it achieves superior accuracy. Additionally, the product includes a fixed bracket for installation.

1.2 Detection principle

Radar level sensor is based on the principle of time domain reflection (TDR). The electromagnetic pulse propagates along the cable or probe with the speed of light. When it meets the surface of the measured medium, part of the pulse of the radar level meter is reflected to form an echo return to the pulse transmitter along the same path, and the distance between the transmitter and the surface of the measured medium is In direct proportion as the propagation time of the pulse, hence the height of the   level is calculated.

2.Feature
