Basic Elements of the Analyzer

The WDG-V UOP analyzer is a complete standalone unit; no separate controller
is required. The unit consists of three basic systems:

•

Plumbing

Includes all inlet and outlet tubing, O

2

Cell Housing, the calibration gas

inlet and aspirator assembly, flow sensor, and the aspirator used to pull the
sample into the analyzer.

•

Measuring System

Includes the oxygen Cell and flow sensor.

•

Temperature System

Includes the electrical Cell heater (furnace), sensor case heaters, the Type K
Thermocouple (maintains Cell operating temperature). The sensing Cell
operates at a constant temperature. The WDG-V is a complete standalone
unit. No separate controller is required.

Analyzer I/O

All required I/O comes with the analyzer. See the section “About the Analyzer
Electronics” for descriptions.

Analyzer Communications

The analyzer is configured, calibrated and monitored using the MODBUS RTU
interface. AMETEK provides two options for communicating with the analyzer:

• AMEVision Display User Interface

• WDG-V UOP Configurator Software via PC (standard with each unit)

The interface is industry standard MODBUS which allows customized
user software. Contact the factory for the MODBUS register definitions.
