    1.1 PR-23 refractometer models The basic system of one or two sensors connected to an Indicating transmitter (DTR) is the same for all PR-23 inline refractometer models. However, there are different sensor models, each model is adapted for different process requirements.

  • 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.

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.

    Figure 3.3. The LCD is best viewed when approximately on the eye level of the user. In sanitary installations, K-Patents recommends using a DTR with stainless steel en- closure. If standard polycarbonate enclosure is used, it should be installed as remotely as practical from the product areas or connections.

    (see upper edge of the display to check which sensor is currently chosen and switch in the Outputs display if necessary). The PR-23 offers three types of signal damping. The damping parameter is set sep- arately through the Outputs menu selected from the Calibration menu by 2 OUTPUTS What the damping time means in practice depends on the damping type.

  • Page 50: Linear Damping

    PR-23 instruction manual 6.1.2 Linear damping If the process has fast step changes, linear (fast) damping gives shorter settling time. In the linear damping (fast damping), the output is the running average of the signal during the damping time. After a step change the signal rises linearly and reaches the inal value after the damping time.

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

  • Page 188: 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 189: 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 190: 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 lashes during ping. If the LED does not lash, re-check the IP address (so that you are really pinging the DTR in question).

  • Page 191: Remote Panel

    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 igure 12.10 above uses a different address, not the default).

  • Page 192: 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.
