Name

Microwave-based
flowing-powder detector

Model

D-MM3

Object
to be
measured

Powders flowing in a container, tank or silo

Description

This device is designed to detect, in a manufacturing process, powder flowing in a tank. It can be used in a broad range of applications with its setting capability ranging from minimal to large amounts. The microwave-based flowing-powder detector is free from the need to protrude in the tank since its sensor is designed to have a flat face.

Operating
principles

With the Doppler effect applied in it, this instrument is designed to detect the microwave that is reflected or absorbed by the powder and/or granular material through which the microwave radiated at the point of measurement can pass.

Construction

The device to radiate the microwave and the wave detector are both built in this detector. The detector extracts, from the microwave, a signal proportional to the peak value of the microwave and outputs it as a contact point signal. The sensitivity of the detector is directional, peaking in the axial direction and decreasing in directions deviating from the axial.
