The calibrated range of the 3050-AMS is 0–100 PPMV with a trend indication for measured concentrations to 1000 PPMV.

Contact Closure Signals The 3050-AMS Analyzer provides the following contact closure signals. System Alarms 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.
Moisture Sensor Quartz Crystal Microbalance (QCM) The 3050-AMS Analyzer uses a QCM Sensor to measure water vapor concentra- tion. This is a piezoelectric device that is capable of extremely sensitive mass measurement. To make the QCM sensitive to water vapor the surface is coated with a thin film of hygroscopic material.
Gas Flow Sample System The 3050-AMS Moisture Analyzer sample system enables the analyzer to make reliable water vapor measurements at concentrations down to 0.035 PPMV. The sample system serves several purposes: • It controls the sample conditions at the Sensor assembly (e.g., flow rate, temperature, pressure).
Sample Flow In the normal operation of the 3050-AMS Analyzer, the Zero module (the sec- tion enclosed in the dotted line in Figure 1-2) is turned off so that the Sample gas enters the analyzer and passes through diaphragm valve 2 (DV2). After exiting DV2, the flow splits into two (2) paths: the Sample gas path and the Reference gas path.
Zero Gas Module The Zero gas module, shown inside of the dotted rectangle in Figure 1-2, is used to provide a dry gas stream at the inlet of the analyzer. Functionally, the Zero gas module is a very simple device, consisting of only three (3) diaphragm valves and a dryer.
Dew point values are calculated from the moisture concentration measure- ments (PPMV) and the sample or process pressure. For temperatures below 0 °C, the 3050-AMS uses equations to determine the water vapor pressure over ice, rather than over super-cooled water. Thus, the 3050-AMS reports a frost- point temperature consistent with the physical form of the condensed phase in a real process stream.
(ISO 18453, which is based on the work presented in GERG-Water Correlation: GERG Technical Monograph TM14, 2001), AMETEK has provided a means of using either method in the 3050-AMS product. Specifically, in the gas list we have cited two (2) separate entries for natural gas. The first entry is labeled “Natural Gas, ”...

Unpacking and Inspecting the Equipment Remove any packing material from the 3050-AMS Moisture Analyzer ship- ping crate. Check for damage. If equipment is damaged, notify the carrier and contact AMETEK (https://www.ametekpi.com/customersupport/aftermarket) immediately if parts are missing or damage is found, and to verify if damaged parts will require replacement prior to safely installing and operating the ana- lyzer/equipment.
Electrical Requirements The 3050-AMS Analyzer must be installed in a general purpose area. It does not have an On/Off power switch so power must be applied through a circuit breaker switch at the AC source. General Purpose Installation: • Power connection can be made using the supplied power cord(s) termi- nated with a locally approved wall socket plug, or •...
Optimal results are obtained with the sample line maintained at 60 °C. Recommended Sample gas input tubing is 1/4-inch OD, electro pol- ished 316L VAR stainless steel (AMETEK Part No. 257707002 or equiva- lent). Exhaust pressure must be atmospheric.

Communication Connections – Analog Outputs, Alarm/Data Valid, RS-232/RS-485 To make the communication connections (refer to Item numbers in Figures 2-9 and 2-2): 1.

Overview of Display The default display has four lines (Figure 2-13): Line 1 Sample concentration Line 2 Status message Line 3 Alarm message Line 4 Alarm value There is also a series of dots after the “Status” message that “beat” to indicate the analyzer is functioning.
If the concentration value is still decreasing after the initial dry down period, allow additional dry down time. The 3050-AMS Analyzer is now fully operational with factory default configu- ration of the analog output and concentration alarms. You are ready to do an initial Zero cycle.
Procedure for Speeding up the Dry Down Period To decrease the time required to dry down the 3050-AMS Analyzer: 1. Make all gas connections and apply power to the analyzer. Allow the ana- lyzer to warm up and run with the factory-default settings for a period of 6 to 12 hours.
Configuring the 3050-AMS Analyzer for Serial Communications Protocol The protocol used for the 3050-AMS Analyzer is a master/slave, command/ response communication with the master initiating all transfers. The message format for transfers initiated by the master is illustrated in Figure 2-15.
Page 47
The checksum for a slave response is the modulo 256 sum of all characters pre- ceding the checksum including the response code. The message format for slave responses containing a data field is illustrated in Figure 2-16. Data End Flag Figure 2-16.
The commands that can be issued from the master are listed in Figure 2-19. Command Byte Function Echo Bad Command Acknowledge Read Data Not Used Write Data Write Cell EEPROM Quit Zero Analyzer Reset Toggle Test Mode Figure 2-19. Initiate Zero Defined Commands table. 2-24 | 3050-AMS Moisture Analyzer PN 305804902, Rev A...
Echo (A) Echo implements a loop back function to test the integrity of the serial com- munication. Any text transmitted by the master is returned. Example: Master: >99ABCDEFG4E[CR] Slave: AABCDEFG1D[CR] Bad Command (B) This command is not recognized by the slave. It will therefore result in a type 01 failure response.
Zero cycle is terminated immediately and normal operation resumed. Example: Master: >34QB8[CR] Slave: A[CR] Zero (Z) Initiates a Zero cycle. Example: Master: >34Z??[CR] (Note the use of wildcard in place of checksum) Slave: A[CR] 2-26 | 3050-AMS Moisture Analyzer PN 305804902, Rev A...
Defined Responses (Slave to Master) There are three (3) possible responses to a communication transfer initiated by the master. These are a Simple Acknowledge, Acknowledge with Data, and a Failure message. Simple Acknowledge If the received command does not require data to be returned, a simple ac- knowledge consisting of an ASCII ‘A’...
