  • Page 10: Wet Section Unit

    9033X 1.3.1 WET SECTION UNIT The 9033X Sodium system is capable of monitoring sodium concentrations in sample feed. Three solenoid valves are used to select between analyzing the sample, calibration solution 1 (CAL1), calibration solution 2 (CAL2) and grab sample.

  • Page 11: Pre-Amplifier

    9033X 1.3.2 PRE-AMPLIFIER The 9033X Sodium analyzer requires a pre-amplifier unit which amplifies and converts the voltage output from the electrodes into proportionate current. Thermistor output is also fed to transmitter unit via pre-amp section. The pre-amplifier houses the wiring connection terminals from electrodes.

  • Page 12: Location And Layout

    2.1.1 LOCATION AND LAYOUT Mount the analyzer in a clean, vibration-free area avoiding direct radiant heat, sunlight and drafts. Avoid areas containing chlorinating equipment. The 9033X Sodium analyzer default design has the two main sections (transmitter and wet section) combined as a single unit.

  • Page 23: Operating The Analyzer

    Drain Figure 15. Sample flow during normal operation. The 9033X Sodium analyzer system is comprised of a stainless steel backplate. The internal hydraulic components and pipe work are mounted directly onto the metal backplate. Sample enters through the inlet compression fitting at the bottom of the case and first passes through the sample flow switch before going to the heat exchanger.

  • Page 25: Alarms

    3.2 ALARMS Sample Concentration Alarms When the 9033X Sodium system is in normal operation mode one alarm operates as a “low” alarm and the other operates as a ‘high’ alarm. Alarm 1 (A1) operates as a LOW alarm and is activated when the sodium level decreases below the set value. Alarm 2 (A2) operates as a HIGH alarm and is activated when the sodium level increases above the set value.
