KLD806 80GHz Radar Level Sensor With Purge Function For Strong Dust Application In Flour Silos

The state of the agriculture industry and the scale of operations in today’s market has demanded more effective tools for grain management. Where a silo level monitoring system of the past could have used manual or mechanical methods to determine grain levels, many of the silos used today are massive, making these systems highly impractical.
Today, silo-level radar is a popular method for designing an efficient bin-level measurement tool. Silo radar level measurement uses a pulse generator and a grain bin fill sensor to determine the level of solids present in the silo. The pulse is transmitted down a contact cable or rod, then returns when it encounters the change in dielectric marked by the shift from air to the grain. The system then calculates the travel time of the pulse to determine the grain silo level measurement.
Another method of wireless bin monitoring employs ultrasonic sensors to launch and receive a mechanical pulse that detects a level-based density change. These systems are relatively small and tend to be highly cost-effective. However, since sound waves are affected by both moisture and ambient temperature, ultrasonic bin level monitors are not ideal for humid environments or those prone to significant temperature fluctuation.
A more robust solution, laser silo level sensors require no contact and can accurately detect grain levels at a long-range. These wireless bin monitoring systems are less subject to environmental interference and will perform well even in tall, narrow silos thanks to their concentrated beam style of measurement.

When using flange installation, the minimum distance between the instrument and the tank wall should be 200mm.
① datum plane
② vessel center or axis of symmetry

When installing the instrument, avoid installing it above the material inlet, and try to avoid various objects that affect the signal, such as stirring paddles, etc.

Under extremely complex working conditions, the instrument can work normally if there is no obstacle in the area with a radius of 20cm centered on the installation point.

The maximum installation spool height H max depends on the installation spool diameter D and the size of the product launch angle.
Too long installation connection will affect the radar performance.
