  • Page 11: Introduction

    1 Introduction 1 Introduction The K-Patents PR-23 inline refractometer is an instrument for measuring liquid con- centration 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.

  • Page 12: Principle Of Measurement

    PR-23 instruction manual 1.2 Principle of measurement The K-Patents inline 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.

    3 Indicating transmitter DTR 3 Indicating transmitter DTR 3.1 Indicating transmitter description The Indicating transmitter DTR is a specialized computer designed to process data received from one or two sensors. The Indicating transmitter enclosure (Figure 3.1) contains a front panel with a backlit Liquid Crystal Display (LCD) and a keyboard. The front panel swings open to give access for connections and service.

    12 Ethernet connection specification 12 Ethernet connection specification The Ethernet connection enables data download from a DTR to a computer. The con- nection works both directly between DTR and computer or via a hub or switch, local area network (LAN), wireless network (WLAN) or fiber Ethernet. Any type of computer (PC, Mac, PDA, mainframe...) with a compatible network con- nection can be configured to download data from the DTR.

    12 Ethernet connection specification Figure 12.6 Ethernet connector on the underside of the Front panel. Note: The DTR has automatic speed negotiation, i.e. it will automatically find out what the optimal speed for the connection is and choose accordingly either 10 Mbit/s or 100 Mbit/s speed.

  • Page 178: 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 179: 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 180: 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).

    12 Ethernet connection specification Opening the instrument homepage: 1. Establish a working Ethernet connection (see above) to the DTR. 2. Start your preferred web browser (for example Internet Explorer, Mozilla Firefox, Safari, Opera or Chrome). 3. The address (URL) of the instrument homepage is the DTR’s IP address, for a fac- tory set DTR it is http://192.168.23.254/ (the figure 12.10 above uses a different address, not the default).

  • Page 182: Collecting Data Via Ethernet

    The main purpose of the Ethernet connection is to collect measurement data from the instrument. For this data acquisition, you’ll need to have suitable software on your computer. One solution is to get the software package from K-Patents. The package contains a ready-to-use data acquisition program for Windows 2000/XP/Vista.

    The sample holder keeps the sample on the prism surface and also keeps the ambient light out. The K-Patents universal sample holder PR-1012 (Figure 13.1) can be used with any K-Patents PR-23 sensor (in PR-23-M only the top part of the sample holder is needed).

  • Page 188: Verification Procedure

    As the specified accuracy of PR-23 is ±0.0002, then the representative level is the sum of the three accuracy specifications, that is ±0.0004. K-Patents provides a set of standard R.I. liquids, PR-2300, containing these five liquids. The set can be ordered directly from K-Patents or through your nearest K-Patents rep- resentative. 13.2 Verification procedure To start the verification process, select in the Main menu of your sensor.
