ABB 61615-0-1200000 Panel controller

Close Coupled Sampling System

The sensor assembly is mounted on the process wall and the probe and filter assembly extends into the process gas stream.

A pneumatic injector is used to draw a sample from the process stream and feed it to the sensor head.

Oxygen analysis is performed by an industry standard zirconia cell.

Carefully metered dilution air is added and then calibrated for COe before the high sensitivity catalytic sensor is used to measure unburned combustibles.

The dilution air ensures a sufficient supply of oxygen to allow the COe sensor to function properly under abnormal

process conditions where extremely low combustion oxygen levels may occur.

The tightly coupled extraction system enables tight temperature and pressure control of the sensor and sample gas.

This provides a stable background for target gas measurements, which improves the accuracy of the measurements.

Flame arrestors are installed in the sampling path to prevent flashbacks during startup when the combustible

content of the process gas exceeds the Lower Explosive Limit (LEL), thus ensuring safe operation.

Flashback is prevented if the combustible content of the process gas exceeds the Lower Explosive Limit (LEL) during startup, shutdown, or process disturbances.

The sampling channel is kept hot to prevent acid gas condensation and corrosion.

Benefits of using TIM foils in comparison to thermal grease are easier installa tion and more durable heat

transferring properties for longer periods of time. Durability par ticularly improved in a cyclic application.
