Chapter 6 Optimising Sensor and Process Performance
The sensor is a precise instrument and in many cases is more accurate than the equipment or
sampling techniques used for calibration purposes. For best performance ensure that the installation
follows the basic guidelines below and that the sensor is configured with suitable filtering parameters.
It may also be beneficial to adjust the sensor filtering and signal smoothing parameters as described
in Chapter 4.
Selecting an alternative measurement mode (see Chapter 5) may give a more desirable signal
response but before doing so the performance of each mode should be monitored using the Hydro-
Com software.
1 General to all Applications
•
Power Up : It is recommended to allow the sensor to stabilise for 15 minutes after
applying power before use.
•
Positioning : The sensor should be in contact with a representative sample of the
material.
•
Flow : The sensor should be in contact with a consistent flow of material.
•
Material : If the material type or source changes this may affect the moisture reading.
• Material particle size : If the particle size of the material being measured changes this
may affect the rheology of the material for the same moisture content. Increased fine
material often leads to a ‘stiffening’ of the material for the same moisture content. This
‘stiffening’ should not automatically be regarded as a reduction in moisture. The sensor
will continue to measure moisture.
•
Material build up
: Avoid material build up on the Ceramic faceplate.
2 Routine maintenance
Ensure that the ceramic measurement faceplate is always free from build-up of material.
Fit the Standard Mounting Sleeve (part no 0025), the Extension Mounting Sleeve (part no 0026)
or the Flanged Mounting Sleeve (part no 0024A) with Clamp Ring (part no 0023) for ease of
adjustment or extraction.
DO NOT HIT THE CERAMIC FACEPLATE DURING MAINTENANCE
