3、 Zero Maintenance Design: Reshaping the Cost Model of Industrial Measurement Equipment

VEGAThe radar level transmitter adopts a solid-state design without mechanical moving parts, combined with self-cleaning antenna technology, to achieve truly maintenance free operation:

Self diagnostic function: The built-in intelligent monitoring system can detect the degree of antenna contamination in real time, and automatically trigger a cleaning prompt when the return loss exceeds the threshold

Non contact measurement: Avoid medium contact and eliminate the jamming fault caused by medium crystallization and scaling in traditional level gauges

Modular structure: The sensors and electronic modules are designed for quick insertion and removal, reducing on-site replacement time to15minute

According to the liquid level measurement and renovation project of a desulfurization absorption tower in a certain power enterprise,VEGAAfter the radar level gauge is put into operation, the annual shutdown maintenance time is from72Reduce hours to3The absorption tower overflow accident caused by inaccurate liquid level measurement has been eliminated in hours.
