Product Description

Printer Version

The Process Gas Sampling System connects a gas analyzer to multiple gas-samplinglines via a valve/manifold system. The valve bank is modular to accommodate various gas sampling system needs. Each module consists of four stainless steel valves. Sample scheduling is set to continuously cycle through the sampling ports, one after another.

The system includes a multi-port-purge system that uses an auxiliary pump to simultaneously pre-purge one or more sample lines while simultaneously analyzing gas in a specified line. This shortens the time between port-gas measurements by keeping the sample lines filled with fresh sample gas. Sample time at each port is typically 10 to 15 seconds. A PC-based control system running MS Windows 2000 is required to operate the sampling system. ARI supplies the sampling system software and system setup to user specifications.

The system also includes ARIís nitrogen back flush system. Should any of the sampling lines become restricted or plugged, pressurized nitrogen can be forced backwards down the line to clean it. The sampling system optionally includes highpressure calibration gas cylinders mounted within an enclosure. Each calibration gas has its own on/off valve and pressure regulator. A system may optionally include continuous monitoring of gas pressure and temperature from multiple locations.
