  • Page 11: Introduction

    1 Introduction 1 Introduction The PR-23 inline refractometer is an instrument for measuring liquid concentration in the process line. The measurement is based on the refraction of light in the process medium, an accurate and safe way of measuring liquid concentration. The inline refractometer sensor (in Figure 1.1) measures the refractive index n the temperature of the process medium.

  • Page 12: Principle Of Measurement

    PR-23 instruction manual 1.2 Principle of measurement The refractometer sensor determines the refractive index n of the process solution. It measures the critical angle of refraction using a yellow LED light source with the same wavelength (580 nm) as the sodium D line (hence n ).

  • Page 13: General Safety Considerations

    1 Introduction The position of the shadow edge is measured digitally using a CCD element (Fig- ure 1.4) and is converted to a refractive index value n by a processor inside the sensor. This value is then transmitted together with the process temperature via an interconnecting cable to the Indicating transmitter for further processing, display and transmission.

  • Page 210: Testing The Ethernet Connection

    PR-23 instruction manual If you are using Windows (or Mac OS X 10.3 or newer or any recent Linux distrib- ution) and the computer has the default network settings, change the DTR IP ad- dress to 169.254.x.y, where x=1–254 and y=1–254, for example 169.254.100.100 or 169.254.123.1.

  • Page 211: Troubleshooting The Connection

    12 Ethernet connection specification very simple: go to the command interface (for example the Command Prompt), type the name of the command and the IP address you want to check and press Enter. If the Ethernet connection is good, the DTR is powered on and the address given to ping is correct, the DTR will answer to ping and return any data packets sent to it, see Fig- ure 12.8.

  • Page 212: Instrument Homepage

    PR-23 instruction manual If the green LED is lit, your Ethernet connection is made correctly with the right type of cable. In this case, try pinging the DTR and check if the orange LED flashes during ping. If the LED does not flash, re-check the IP address (so that you are really pinging the DTR in question).

    The main purpose of the Ethernet connection is to collect measurement data from the instrument. You can program a downloading facility yourself following the specifica- tions below. Note: Vaisala guarantees that the specifications are correct, but cannot assume any responsibility or provide support for software. 12.5.1 Communication protocol The communications protocol is based on UDP/IP to port 50023.

    12 Ethernet connection specification Response format The response data sent by the DTR is in ASCII format. With the exception of the packet number, the data is human-readable. The data structure is very simple: – packet number (32-bit integer) – zero or more lines of ASCII (text) keys and values associated with these keys (for example temperature key and process temperature in Celsius) The packet number is echoed back without change.
