3 Sensor connection and configuration
As with other Hydronix digital microwave sensors, the Hydro-Probe XT may be remotely
configured using a digital serial connection and a PC running Hydro-Com sensor configuration
and calibration software. For communication with a PC, Hydronix supply RS232-485 converters
and a USB Sensor Interface Module (See page 31).
There are two basic configurations by which the Hydro-Probe XT can be connected to a batch
control system:
• Analogue output – A DC output is configurable to:
•
4-20 mA
•
0-20 mA
• 0-10 V output can be achieved using the 500 Ohm resistor supplied with the sensor
cable.
• Digital control – an RS485 serial interface permits direct exchange of data and control
information between the sensor and the plant control computer. USB and Ethernet
adapter options are also available
The sensor can be configured to output a linear value of between 0-100 unscaled units with the
material calibration being performed in the control system. Alternatively it is also possible to
internally calibrate the sensor to output a real moisture value.
