3 Sensor connection and configuration

As with all Hydronix digital microwave sensors, the Hydro-Probe SE can be remotely configured
using a digital serial connection and a PC running Hydro-Com diagnostics software. For
communication with a PC, Hydronix supply RS232-485 converters, a USB Sensor Interface
Module and an Ethernet Adapter Kit (see Chapter 3).
The Hydro-Probe SE can be connected to a control system in three ways:

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, USB Sensor Interface Module or Ethernet
Adapter permits direct exchange of data and control information between the sensor and
the plant control computer.

Compatibility mode - Not used in this sensor.
The digital inputs and output enables the moisture to be averaged when material is flowing,
essential for obtaining representative moisture for process control.
