  • Page 15: Overview

    Overview The 5920 Moisture Analyzer measures trace concentrations of moisture in ultra-high purity gases such as air, oxygen, hydrogen, helium, argon, air, neon, xenon and nitrogen at concentrations down to 1 parts-per-billion by volume (PPBV) using a quartz crystal microbalance sensor. Calibrated range is 0–150 parts-per-billion by volume (PPBV) with a trend indication for measured con- centrations above the calibrated range.

  • Page 17: Contact Closure Signals

    Contact Closure Signals The analyzer provides the following contact closure signals. System Alarm Activates (contact opens) when a condition exists that makes analyzer output questionable. Such conditions include: • Cell Temperature alarm • Zero error • Battery alarm Moisture Concentration Alarm Activates (contact opens) when a moisture concentration exceeds the pro- grammed alarm levels.

    The difference between these two frequency measurements is known as the delta frequency (∆ ƒ). The ∆ ƒ value is a function of the moisture con- centration in the sample gas. 1-4 | 5920 UHP Moisture Analyzer PN 592047901 Rev YC...

  • Page 21: Solenoid Valves

    Solenoid Valves The sensor assembly is connected to both legs of the analyzer, and immedi- ately downstream of the connection points, there are two (2) solenoid valves (SV1 and SV2). These two solenoid valves switch the flow of the Sample and dry Reference gases through the QCM sensor.

  • Page 22: Verification With External Challenges

    Verification with External Challenges Unlike previous AMETEK UHP moisture analyzers, the 5920 does not contain an internal moisture standard. In AMETEK’s line of QCM-based moisture analyzers, the primary purpose of the internal moisture standard is to monitor the sen- sor’s response characteristics and to enable on-line compensation for sensitiv- ity changes that occur over time.

  • Page 23: Zero Cycle

    AMETEK recommends performing a Zero every 24 hours for the first month of operation. After this start-up period, the analyzer will have dried down sufficiently to increase the Zero interval to 1 week. AMETEK recommends that the duration of the Zero cycle be set to 48 (i.e., 2 hours).
  • Page 24 5900 analyzers is estimated to reach 10 % (i.e., a 2 PPBV change at 20 PPBV) after 45 months of service. Even though the QCM-based moisture analyzers are extremely stable, AMETEK recommends that you check the calibration of the analyzer every three (3) years.
