The sample probe is installed to extract a representative sample from the exhaust gas of the ship engine. If several engines or combustion processes onboard are to be monitored, one sample probe must be installed per engine.
The heated sample transport line consists of a pre-assembled tube bundle with its own electrical heat tracer cable. An aluminum jacket holds the heat cable and the sample tube together. A high efficient insulation material is wound around the tracer and the sample tube, and a weather protective outer sheet covers the entire tube bundle. The tube bundle is designed for outdoor installations, but end seals must be used to avoid ingress of moisture.
The Sample Conditioning System is enclosed by a specially designed cabinet. This cabinet is made of stainless steel, and is wall -mounted. The complete assembly is designed for mounting to a support welded on the ship casing. The purpose of the Sample Conditioning System is to treat the exhaust gas sample extracted by the sample probe via the heated sample transport line. This sample is wet, but the temperature is kept above dew point.
The Analyser Cabinet is enclosed by a specially designed cabinet. This cabinet is made of stainless steel, and is wall -mounted. The cabinet is standing on top of two compression cushions to minimise the effects of high gravitational forces when the ship is moving into heavy seas. The cabinet is supported on the rear of the wall frame by soft anti-vibration cushions to reduce the impact of horizontal vibrational movements.
