    A sample conditioning system (SCS) is included with the analyzer. The SCS has been specifically designed to deliver an optimum sample stream that is representative of the process systems stream at the time of sampling. Most SS2100 analyzers are configured for use at extractive natural gas sampling stations. Determining Firmware Version When the analyzer is powered on for the first time, the firmware version will display on the system LCD for approximately seven seconds.

  • Page 26: Hardware And Tools For Installation

    Mounting hardware (e.g., spring nuts, 3/8” x 1-1/2” machine screws and nuts) Bolts or screws used for wall-mounting the SS2100 must be able to support four times the weight of the instrument (approximately 59 kg [130 lbs] with sample system).

  • Page 27: Mounting The Analyzer

    Due to the analyzer’s size and weight (configurations can weigh approximately 59 Kg or 130 lbs), SpectraSensors recommends the use of a forklift, pallet jack, etc. to lift and/or move the analyzer. If the analyzer is to be lifted by hand, designate multiple individuals and distribute the weight among personnel to avoid injury.

  • Page 28: To Mount The Analyzer

    Refer to “Lifting/carrying the analyzer” on page 2-3. SpectraSensors analyzers are designed for operation within the specified ambient temperature range. Intense sun exposure in some areas may cause the analyzer temperature to exceed the maximum.

  • Page 45: 3: Sample Conditioning System

    Typical SCS Component Overview All SpectraSensors TDL analyzers are designed for extractive sampling rather than in situ applications. This allows for sample conditioning, filtration, temperature, pressure and flow control to protect the optical components of the system, and provides for ease of maintenance without shutting down the process.

  • Page 46: Sample Conditioning System Filters

    SCS Pressure Regulator All SpectraSensors’ TDL cells are limited to a maximum 10 PSIG pressure. To ensure that this pressure is not exceeded, a pressure regulator is provided inside the sample system.
