  • Page 5: Installation

    Installation Introduction The 2000 Series is a compact unit designed to provide years of accurate, dependable gas monitoring. All of the electronic controls are contained inside a NEMA 4X stainless steel enclosure. The 2000 Series contains one or two sensitive measurement heads (depending on number of target gases analyzed).

  • Page 7: Mounting Procedure

    Ambient pressure: 10 PSIA to 16 PSIA (sample cell pressure: 10 - 25 PSIA) Mounting Procedure The 2000 Series is designed to be bolted to a wall or other flat surface that is free of vibrations. Minimizing the gas volume of the sample system and using stainless steel tubing optimizes performance.

    The inlet line should also have a shutoff valve to prevent gas flow into the analyzer when it is not in use. The outlet line of the 2000 Series is connected to a ¼-in. O.D. stainless steel line that vents the sampled gas to ambient air outside the sampling station.

    Operation Specifications for Proper Use The 2000 Series is designed specifically to measure levels of moisture, and carbon dioxide in a gas stream. It also reports dew point, temperature and pressure of the sampled gas. Although the unit can easily be dismounted and moved from one sampling station to another, it is designed to be a stationary measuring device.

    The power-down procedure is simple. Remove the power cable from the AC outlet or disconnect power from the gas sensor circuit in the case of a hardwired system. There is no specific sequence beyond that for shutting down 2000 Series gas sensors.

  • Page 28: Maintenance

    Procedure for Cleaning Contaminated Mirrors The 2000 Series is intended to measure very clean low water content gas (no more than 20 lbs/MMscf). SpectraSensors has other models available that are capable of measuring gas with higher moisture concentration. The sample gas inlet line must have a coalescing filter to prevent contamination of the internal optical components.
  • Page 29 Method: SpectraSensors recommends using a solvent rinse cleaning process to avoid the possibility of scratching the optics. In most cases this should be sufficient to restore the optics to usable condition. A suitable cleaning kit is available from your local sales representative.
  • Page 30 7. Set the mirror assembly aside in a clean area. 8. Gently spray some solvent onto the o-ring and wipe it clean with a clean, dry, lint-free wipe. 9. Put a small dab of non-outgasing grease on the o-ring and wipe it off. © 2001, SpectraSensors, Inc.
