  • Page 11: Chapter 1 Introduction

    Introduction 1 Introduction The Hydro-Probe SE is a digital microwave moisture / Brix sensor designed for use in higher temperature environments and pressurised vessels and to have a wear life of many years. The Hydro-Probe SE measures the material passing in front of the ceramic faceplate. Its on- board processing provides the options of both an analogue and a digital output which can be easily connected to any control system.

  • Page 12: Sensor Connection And Configuration

    Introduction 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).

  • Page 13: Chapter 2 Mechanical Installation

    The optimum location for the sensor varies depending on the type of installation – a number of options are detailed on the following pages. Care should be taken to ensure that the Hydro-Probe SE has been correctly installed and in such a manner to ensure representative sampling of the material concerned. It is essential that the sensing part of the unit is fully inserted into the main flow of the material.

    Chapter 2 Mounting in a pipeline measurement chamber If the Hydro-Probe SE is to be installed in a measurement chamber in-line with a pipeline the chamber must remain completely full at all times to achieve reliable results. A bypass line should be installed to facilitate any maintenance of the sensor (Figure 6).

  • Page 25: Chapter 4 Configuration

    Configuration 1 Configuring the Sensor The Hydro-Probe SE has a number of internal parameters which may 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 (HD0273).
  • Page 26 2.2.6 Material Temperature The Hydro-Probe SE has a temperature sensor attached to the metal of the sensing head. This can be used to output the current material temperature. The output value is set at 0°C equals 0mA (or 4mA dependent upon the output set-up) and 100°C equals 20 mA.

    (0) value relates to the measurement in air and 100 relates to water. This is used to give a raw output value from a Hydronix sensor which ranges from 0 to 100 and is called the Unscaled value.

  • Page 32: Storing Calibration Data

    For further advice regarding specific applications please consult the Hydronix support team support@hydronix.com The Calibration Types The Hydro-Probe SE can be calibrated to a moisture percentage or a Brix Value. A material calibration for moisture is normally linear, and calibrating to this is described in Chapter 5 section 3.

  • Page 33: Moisture (Linear) Calibration

    No need to learn how to use additional software.  If it is necessary to replace the sensor, a replacement Hydronix sensor can be connected and valid results obtained immediately without connecting the sensor to a PC to update the material calibration.

    Free moisture Total moisture The SSD Coefficient used in Hydronix procedures and equipment is a value that relates to the water absorption properties of the material, sometimes referred to as the Water Absorption Value (WAV). This value is determined by more complex means than oven drying and may usually be obtained from the material supplier.
