    Model 210BR Oxygen Analyzer Introduction The Advanced Micro Instruments Oxygen Analyzer Model 210BR provides the latest in high precision oxygen measurement. It is specifically designed for use with flammable gases in hazardous areas, and includes a number of features that make it particularly suitable for this application. It is approved by CSA to UL standards for Class 1 Div.

  • Page 7: Oxygen Sensor

    The sensor is warranted to operate for a period determined by its class. If the sensor ceases to operate correctly before this time has elapsed, contact AMI for a return authorization for evaluation. If there is any evidence of defective material or workmanship the sensor will be replaced free of charge.

    Sample conditions – if your sample is hot and wet, you will need to keep water from condensing in the sample line or analyzer. The AMI demister brings hot and wet gases back to ambient temperature and allows the condensation and entrained liquids to fall back into the pipeline (no draining is necessary, unlike a coalescing filter which requires routine maintenance).

If the sample pressure is high, the volume is effectively increased because more gas is packed into the tubing. AMI can provide a version of the Liquid Rejection Probe with a built-in regulator that can handle pressures up to 1500psig.

    Figure 6. Analyzer without lid The 210BR measures oxygen in a flammable (or inert) gas stream down to under 0.1%. It is approved for use in hazardous areas when properly installed. It consists of two major parts mounted on a common back plate. The enclosure on the right contains the gas handling components including the oxygen sensor, and also the controls and analytical circuitry.

  • Page 26: General Information

    As a consequence of this, the integrity of the oxygen analyzer sample system is critical. AMI analyzers are designed around a patented “Cell block” that integrates all of the sample handling elements into one solid chunk of metal, resulting in much fewer leak sources and therefore much greater reliability, as well as lower cost.

  • Page 27: Analyzer Operation

    The span gas pressure should also be held below 100psig. AMI recommends that you use a length of their flexible tubing with O ring seals on its fittings so that you don’t damage the analyzer fittings by making and breaking them too often.
  • Page 28 Fist put a suitable regulator on the span gas tank. Connect the regulator to the analyzer with a flexible line such as that provided by AMI, and leak check the connection with “Snoop™” or similar leak detection fluid. Purge the line for several minutes with a small flow of gas prior to doing this, and leave the gas flowing while you make the connection to the analyzer.

  • Page 29: Using The Analyzer

    Communications The 210BR supports both a USB link to a local PC, and RS485 over a network. Only one of these can be active at a time, and the unit automatically turns off the RS485 if it detects a computer plugged into the USB connection.

  • Page 30: Advanced Features

    Advanced Features The analyzer has many advanced features that are only accessible through the AMI User Interface. For details see the User Interface manual. The features include a data log, a calibration log, power failure log, and many other detailed bits of data. Most of these features are also available over the ModBus link.

  • Page 31: Maintenance And Troubleshooting

    Maintenance and troubleshooting Maintenance: The model 210BR is virtually maintenance free other than for periodic calibration and occasional sensor replacement. Periodic Calibration: The analyzer should be calibrated about once every month to obtain the best accuracy. The sensor typically declines in sensitivity by about 1% per month, so a monthly calibration is usually satisfactory. Use in a particularly aggressive environment may degrade the sensor faster: in this case calibrate more often.

    9. Replace the cell cap. 10. Screw it down tightly but only hand-tight. 11. Dispose of the old sensor in an environmentally appropriate way. It is similar to a lead-acid battery in terms of environmental hazard. Maintenance and troubleshooting  29 AMI Analyzer Manual...

    AMI’s obligation is expressly limited to the analyzer itself. The AMI analyzer is not designed as a primary safety device, that is to say it is not to be used as the primary means of assuring personnel safety. In particular it is not designed to act as a medical instrument, monitoring breathing air for correct oxygen concentration, and should not be used as such when it is the only safety device on the gas system.
