Microwave Sensor Applications

Flow/Non-Flow & Block Chute Detection
MWS-DP-3

MWS-DP-3

The MWS-DP-3 Microwave Solids Flow Sensor detects moving solids utilizing microwave high penetrability and the Doppler effect.
The sensing head transmits microwaves toward the target material.
A portion of the microwaves are reflected back to the sensing head and analysed as to whether they are from a moving or stationary object.
The highly-penetrable microwave passes through a buildup on the head and even through pipe made of non-conducting materials such as plastics.
It is best suited for detecting such materials as powders, granules, etc, moving through a vacuum pipeline.

Special Features

  • Blocked Chute Detection
    In addition to being used as a solids flow sensor, it can be used as a transmitter in combination with a receiver in order to detect a block chute.
  • Equipped with a filter for screening unnecessary incoming Doppler signals
    This function eliminates unnecessary incoming Doppler signals such as, signals from a vibrating pipe or conveyor and improves the S/N ratio.
  • Equipped with a sensitivity margin indicator
    The received power level and the sensitivity set point are indicated on the sensor allowing for easy visual adjustment and maintenance of the sensor.
    The indicator clearly displays the advantage of the filter screening effect.

Application Example

Flow/Non Flow Detection

Thanks to the filter function, the solids flow sensor detects only the falling material without interference from conveyor 1 or 2.

Flow/Non Flow and Block Chute Detection

The receiver receives microwave beams from the solids flow sensor.
When the beam is inteerrupted, the receiver will output a “blocked chute” signal.
The operating distance between the Solids Flow Sensor and Receiver is up to 80 meters (Standard type) but may vary from sensor to sensor and according to installation circumstances.
When the MWS-SR-2 receiver is used for this application, its channel function cannot be used.
