Hydro-Probe XT digital microwave moisture sensor

The Hydro-Probe XT microwave moisture sensor has been designed with a variety of mounting options. The most typical installation is in or underneath a bin (silo) or above a conveyor or belt feed. These different options provide the installer with flexibility in determining the most suitable location for the sensor to be installed.

The Hydro-Probe XT should be mounted in the flow of material which must pass across the ceramic faceplate of the sensor. To ensure that the material flow is not obstructed and to prevent build up on the sensor face, the moisture probe should be installed at an angle of approximately 60 degrees to the flow of material. For installations where the silo is wide an extension mounting sleeve can be used.

The examples below show diagrams of typical mounting for the Hydro-Probe XT in a bin (silo) and a conveyor or belt feeder.

Full details regarding installation and calibration can be found in the User Guide. This is available for download in many different languages. Details for the extension mounting sleeve and other Hydro-Probe XT accessories can be found on the associated products page.

Typical Examples for Mounting a Hydro-Probe Sensor

Conveyors and Belt Feeders

Hydro-Probe mounted on a conveyor belt

The Hydro-Probe may be mounted on conveyors and belt feeders where there is a minimum material depth of 125mm

Beneath the Bin

Sensor mounted beneath the bin

Where space is very restricted the Hydro-Probe may be positioned below the bin to avoid flow obstruction

In the Neck of the Bin

Hydro-Probe fitted in the neck of a bin

Preferred position - the Hydro-Probe is fitted in the neck of the bin using a standard mounting sleeve.

Wide Bins

Hydro-Probe installed in a wide bin

The extended mounting sleeve will be required with wide bins to ensure that the Hydro-Probe face is in the flowing material.
