Configuration
1 Configuring the Sensor
The Hydronix microwave moisture sensor has a number of internal parameters which can be
used to optimise the sensor for a given application. These settings are available to view and
change using the Hydro-Com software. Information for all settings can be found in the Hydro-
Com User Guide (Hydro-Com User Guide HD0682).
Both the Hydro-Com software and the Hydro-Com user guide can be downloaded free of charge
from www.hydronix.com.
All Hydronix sensors operate in the same way and use the same configuration parameters.
However, not all the functions are used in every sensor application. (Averaging parameters, for
example, are typically used for batch processes).
2 Analogue Output Setup
The working range of the two current loop outputs can be configured for the equipment it is
connected to, for example a PLC may require 4 – 20 mA or 0 – 10V DC etc. The outputs can
also be configured to represent different readings generated by the sensor e.g. moisture or
temperature.
Figure 2 may be used to assist in selecting the correct analogue output variable for a given
system.

2.1
Output Type
This defines the type of the analogue outputs and has three options:
•
0 – 20mA: This is the factory default. The addition of an external 500 Ohm precision
resistor converts the 0-20mA to 0 – 10V DC.
•
4 – 20mA.
