  • Page 13: 3050-Rm Moisture Analyzer

    3050-RM MOISTURE ANALYZER Overview The Model 3050-RM Moisture Analyzer reliably measures moisture con- centrations in a variety of industrial and UHP gases, using a quartz crystal microbalance (QCM) sensor. The calibrated range of the analyzer is 0 to 2500 PPMV. The QCM-sensor technology used in this analyzer is com-...
  • Page 14: Controller / Communications

    One RS-232 or one RS-485 serial interface provides communication be-  tween the analyzer and your recording or data acquisition equipment. The Model 3050-RM analyzer is configured, and analyzer parameters are set, by using either the analyzer display, keypad and function keys, or us- ing an external PC.
  • Page 15: Moisture Sensor

    Moisture Sensor Quartz Crystal Microbalance (QCM) The 3050-RM analyzer uses a quartz crystal microbalance sensor to mea- sure water vapor concentration. This is a piezoelectric device that is capa- ble of extremely sensitive mass measurement. To make the QCM sensitive to water vapor the surface is coated with a thin film of hygroscopic mate- rial.
  • Page 16: Sample Flow

    Sample flow Normal operation of the Model 3050-RM analyzer uses an internal bypass, which increases the response speed of the system. However, the 3050-RM is capable of running in a gas-saver mode as well, which allows the ana- lyzer to run on a sample volume of approximately 150 SCCM.
  • Page 17: Solenoid Valves

    The three-way solenoid valves (SV2, SV3, SV4) are used to select the gas stream that is passed through the sensor; the remaining two streams are passed to the vent. In normal operation of the 3050-RM, the analyzer continuously cycles between the sample- and dry-reference gas streams.
  • Page 18: Verifying The Analyzer

    Dew point values are calculated from the moisture concentration mea- surements (PPMV) and the sample or process pressure. For temperatures below 0 °C, the 3050-RM uses equations to determine the water vapor pressure over ice, rather than over super-cooled water. Thus, the 3050-RM reports a frost-point temperature consistent with the physical form of the condensed phase in a real process stream.
  • Page 19 GERG-Water Correlation: GERG Technical Monograph TM14, 2001), AMETEK has provided a means of using either method in the 3050-RM product. Specifically, in the gas list we have cited two separate entries for natural gas. The first entry is labeled “Natural Gas”, and will provide dewpoint/frostpoint values consistent with ASTM D1142.

  • Page 26: Analyzer Requirements

    Analyzer Requirements Space Requirements The 3050-RM Moisture Analyzer requires an area 48 cm wide x 13 cm high x 42 cm deep (19” x 5.25” x 16.5”) plus rear clearance for analyzer connec- tions and proper ventilation (Figures 3-1a, b and c). It should be located as close to the sample tap as possible.

  • Page 28: Utility Requirements

    Utility Requirements Electrical requirements The 3050-RM Moisture Analyzer must be installed in a general purpose or Division 2 area. It does not have an On/Off power switch so power must be applied through a circuit breaker switch at the AC source.
  • Page 29: Analyzer Installation

    Optimal results are obtained with the sample line maintained at 60 °C. Recommended sample gas input tubing is 1/8 inch OD, electro polished 316L VAR stainless steel (AMETEK #257707000 or equiva- lent). Exhaust pressure must be 0 – 15 PSIG.
