AMETEK 7000-330-SE LCD Host Interface PCB Assembly

Overview

The AMETEK 7000-330-SE is the LCD Host Interface PCB and guard assembly used across the AMETEK Process Instruments AMEVision board set, the display and control electronics platform fitted to AMETEK combustion gas analyzer systems such as the WDG-V, WDG-IV and WDG-HPII oxygen and combustible gas analyzers. This assembly carries the local operator interface logic that drives the analyzer’s LCD display, accepts keypad input, and communicates measurement, alarm and diagnostic data between the analyzer’s core electronics and the field technician standing at the enclosure. It is a genuine AMETEK OEM spare, sold as a direct fit replacement for AMEVision-equipped combustion analyzers already in service.

Seven Star LLC supplies the AMETEK 7000-330-SE as an authorized-partner spare part to refineries, gas processing plants, power stations and cement plants across Oman and the wider GCC that run AMETEK combustion analyzers on their boilers, fired heaters and furnaces. Because the board is model-specific to the AMEVision architecture, it is best ordered against the exact analyzer serial or the previously fitted board’s part number so the correct firmware revision and connector layout is confirmed before dispatch.

Measurement and Operating Principle

The 7000-330-SE itself does not perform gas measurement – that task belongs to the analyzer’s zirconium oxide or infrared sensing cell. Instead, the LCD host interface board is the presentation and control layer of the AMEVision system. It receives digitized process values (O₂ percentage, combustibles, temperature, calibration status) over the internal board-to-board bus from the analyzer’s main processor board and renders them on the front-panel LCD in real time, refreshing continuously so operators can read stack oxygen or combustibles trends without opening a laptop or handheld configurator.

The board also manages the local keypad, allowing on-site calibration, range changes, alarm setpoint adjustment and diagnostic menu navigation directly at the analyzer enclosure. A guard plate is integrated with the PCB assembly to protect the interface electronics from physical damage and to help maintain the enclosure’s ingress rating when the analyzer is mounted in an outdoor or process-adjacent location, which is typical for combustion analyzers installed close to stacks, ducts and fired equipment.

Engineering Design

As part of the AMEVision board set, the 7000-330-SE is engineered to the same industrial reliability standard as the rest of the AMETEK combustion analyzer platform, expected to operate continuously in hot, vibration-prone analyzer houses adjacent to boilers and furnaces. The PCB uses conformal-coated components and a keyed connector interface so it can be swapped in the field without recalibrating the entire analyzer, and the guard plate is dimensioned to bolt directly into the existing AMEVision enclosure footprint without modification.

Because AMEVision is a modular board set, AMETEK maintains strict part-number traceability between board revisions and analyzer firmware; the 7000-330-SE is stocked and supplied as the specific host interface revision for AMEVision-based combustion analyzers, ensuring that display formatting, menu structure and keypad mapping match what the operator has been trained on rather than requiring re-familiarization after replacement.

AMETEK 7000-330-SE Key Features

• AMETEK 7000-330-SE is a genuine AMETEK OEM board – direct fit replacement for the AMEVision LCD host interface assembly
• Drives the analyzer’s front-panel LCD for real-time O₂ and combustibles readout
• Manages local keypad input for on-site calibration and alarm setpoint configuration
• Integrated guard plate protects the PCB and helps preserve enclosure ingress rating
• Conformal-coated construction rated for hot, vibration-prone analyzer house environments
• Keyed connector interface for straightforward field replacement without full recalibration
• Compatible with WDG-V, WDG-IV, WDG-HPII and related AMEVision-equipped combustion analyzers
• Maintains consistent menu structure and keypad mapping across board swaps for operator familiarity

Industrial Applications for the AMETEK 7000-330-SE

The AMETEK 7000-330-SE is used wherever an AMEVision-based combustion analyzer is already installed – refinery fired heaters, power plant boilers, cement kiln preheaters and industrial furnaces where continuous stack O₂ and combustibles monitoring supports combustion efficiency and emissions compliance. When the original host interface board fails or the LCD display becomes unreliable, this assembly restores full local operator access to the analyzer without needing to replace the entire unit.

Seven Star LLC, as an authorized AMETEK partner in Oman, keeps a channel open to this and related AMEVision spares for operators in Sohar, Muscat, Duqm and Salalah who need fast turnaround on combustion analyzer maintenance. Our engineering team can help confirm the correct board revision against your existing analyzer’s serial number and firmware before shipment, minimizing downtime during a plant turnaround or shutdown.
