Introduction

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.
