AMETEK 305110902S Board 3050 DO MCU – Moisture Analyzer Spare Part

Product Overview

The AMETEK 305110902S is a genuine spare printed circuit board for the 3050-DO variant of the AMETEK Model 3050 Moisture Analyzer Series. Designated as the 3050 DO MCU board, this electronic assembly forms the control and communication core of the analyzer, handling measurement processing, digital output and interface functions.

The AMETEK 3050 series is a family of process moisture analyzers used to measure trace moisture in process gas streams. The series uses AMETEK proven quartz crystal microbalance (QCM) technology, providing continuous and reliable moisture measurements from moderate down to very low, sub-1.0 parts-per-million levels. The 3050-DO variant adds digital output capability for integration with control systems.

Technical Specifications

Applications

The 305110902S MCU board is used for repair and refurbishment of AMETEK 3050-DO moisture analyzers installed in natural gas processing, petrochemical plants, olefin production, hydrogen and air separation facilities. Replacing the MCU board restores full analyzer functionality, measurement accuracy and digital communication with plant control systems.

Ordering and Selection

When selecting the AMETEK circuit board, confirm the analyzer model and the board revision required, because each AMETEK 3050 board is built for a specific analyzer variant. The 305110902S is the MCU printed circuit board for the 3050-DO moisture analyzer, and the selected AMETEK 3050 board must be matched to the analyzer serial number and configuration. Our team can help you confirm that the AMETEK 305110902S board you select is correct for your 3050 analyzer.

Maintenance and Support

Circuit board replacement should be performed by qualified technicians, and static precautions must be observed during handling.

Confirming the Board Against Your Analyzer

Several boards are used across the 3050 family, so match the spare to the analyzer rather than to a photograph. Start from the analyzer nameplate, which gives the model variant and serial number, then open the electronics enclosure (with power isolated and area classification respected) and read the part number and revision printed on the installed board. If the numbers on the fitted board differ from 305110902S, share them with us before ordering, because a later revision or a different variant may be required.

• Analyzer model and variant from the nameplate
• Analyzer serial number
• Part number and revision on the installed board
• Current firmware or software version, if displayed

Board Replacement and Re-Commissioning

Before removing the old board, record the configuration: Modbus address and communication settings, analog output ranges, alarm limits and any site-specific parameters. Photograph the connectors and cable routing. Isolate power according to the hazardous area procedures for the analyzer location and use an anti-static wrist strap throughout. After fitting the new board, restore the recorded settings, confirm Modbus communication with the host system and check the analog outputs at a known value. Finally, run a verification against a reference moisture standard or the site’s usual check method before returning the analyzer to service.

Troubleshooting Before You Replace the Board

Not every communication or output fault is caused by the MCU board. Checking the simple causes first can save a board swap and downtime:

• Verify supply voltage at the analyzer terminals.
• Inspect Modbus wiring, termination and address conflicts on the network.
• Look for loose or corroded connectors, particularly in humid coastal sites.
• Review sample system conditions, as flow or pressure problems can look like measurement faults.

Moisture Analysis in Oman and the GCC

Trace moisture measurement is critical in gas processing, LNG pre-treatment, petrochemical feedstocks and industrial gas production across the region. Water in these streams can cause hydrate formation, corrosion and catalyst damage, so a failed analyzer quickly becomes an operational concern. Holding a spare MCU board for critical 3050-DO analyzers shortens repair time considerably.
