Flow transducers use the thermal conductivity principle to determine the volumetric flow (CC/min) of the gas. Various gases have different conductivities, for example, Helium and Hydrogen have a much higher thermal conductivity compared to Argon or Oxygen.

    Figure 44 represents the circuit of Servopro Chroma 4-20 mA. The connection between the Servopro Chroma and the monitoring system must be done using a shielded twisted cable. Connect the load resistor on the monitoring system. A differential input must be used on the data acquisition system to properly monitor the data.

  • Page 97: Fid Fuel Shut-Off Relay/Hydrogen Relay Output

    A fuel shut-off valve can be connected to the rear connector of the analyser. This valve must be normally closed. This valve is controlled by the Servopro Chroma software. When an error occurs, it closes this valve automatically to prevent the accumulation of fuel inside the Servopro Chroma.

  • Page 98: Port

    The Servopro Chroma has a RS-485 port. This port is only used to communicate with other Servopro Chroma systems. It is not design to be used to interface with third party systems. If your system has multiple chassis, you need to connect them using shielded D- sub HD15 Male/Male cable.

    SERVOPRO CHROMA Gas Analyser 7.4.1 Introduction The sampling system is the most important part of your analytical system. The performance of your analyzer can be dramatically limited by your gas transporting system. What we mean, by gas transporting system, any pressure regulator, valve, line, fitting, filter, purifier, etc.

    SERVOPRO CHROMA Gas Analyser 7.4.3 Connecting the Servopro Chroma 1. Once Servopro Chroma installed in a cabinet or rack, remove all caps. It is very important because avoiding removing caps on the outlet will damage the plasma cell. 2. Connect all carrier gas inlets. Make sure that pressure are according to specifications and that lines were properly purged.
