1 General to all applications

Follow the advice below for good sensor positioning:
The 'sensing area' of the sensor (ceramic faceplate) should always be positioned in the
•
moving stream of material.
The sensor should not obstruct the material flow.
•
Avoid areas of severe turbulence. The optimal signal will be obtained where there is a
•
smooth flow of material over the sensor.
• Position the sensor so that it may be easily accessible for routine maintenance,
adjustment and cleaning.
• Care should be taken to prevent damage from excessive vibration by positioning the
sensor as far as reasonably practical from vibrators. If fitting to a vibratory feeder, the
advice from the manufacturer of the feeder should be followed, or alternatively contact
the Hydronix support department.
• The sensor must be angled with the ceramic faceplate initially set to 60° to the flow (as
shown below) to ensure that none of the material sticks to the ceramic faceplate. This is
indicated on the label when the A or B line is perpendicular to the flow.
60˚

If there is a risk that high density material greater than 12mm in size may inadvertently enter the
material flow it is advisable to protect the ceramic faceplate. A deflection plate should be fitted
above the sensor (see Figure 4). The requirements of this must be determined by observation
during loading.
