SS-1200 Sample System

The Southland Sensing SS-1200 Sample System is designed for high-pressure gas applications where process pressure must be safely reduced and controlled before the sample enters the analyzer.

An integral pressure regulator and gauge allow the operator to reduce process pressure and monitor the regulated sample pressure directly at the system. The integral flow indicator with metering valve provides visual confirmation and adjustment of sample flow to the analyzer.

A BYPASS / SAMPLE isolation valve allows the analyzer to be isolated from the process stream while maintaining flow through the sample system bypass. This is particularly useful during startup, shutdown, maintenance, or periods when continuous exposure of the analyzer and sensor to the process gas is not desired.

By combining pressure reduction, analyzer isolation, bypass flow, and sample flow adjustment into a single permanently installed system, the SS-1200 provides a simple and reliable interface between high-pressure process gas and the analyzer.

Analyzer Compatibility: Southland Sensing 150 and 525X Series analyzers for O₂, CO₂, and H₂S measurement.

How It Works

High-pressure process gas enters the SS-1200 and is reduced to the appropriate sample pressure using the integral pressure regulator. The pressure gauge provides visual confirmation of the regulated pressure.

During normal measurement, the selector valve is placed in the SAMPLE position, directing conditioned sample gas through the flow indicator and to the analyzer.

When analyzer isolation is required, the valve is placed in the BYPASS position. Process gas continues to flow through the bypass while the analyzer is isolated from the sample stream.

This arrangement allows the sample system to remain connected to the process while providing a convenient method of protecting or servicing the analyzer.
