Application Note
Rapid Response Time
At four measurements per second, the analyzer can measure the fastest changes in the pipeline. Adjustable, real-time results display every 0.25-2 seconds.
Because the analyzer’s sensor never touches the gas stream, it does not get contaminated. The factory set calibration lasts for the life of the analyzer and reconditioning is never required.
The SS500e very quickly pays for itself by doing away with expensive consumables, extra sensor heads, labor and overhead associated with excessive maintenance. Costs due to unreliable gas measurements can be reduced by eliminating added processing steps, poor gas quality and the possibility of damage to expensive equipment can result from sensors that produce incorrect data.
As with all SpectraSensors analyzers, the SS500e combines a patented laser with control electronics and “smart” software. The analyzer’s sensor heads are not subjected to corrosives or contaminants in the gas because the sensor is isolated from the sample gas stream.
The result is an analyzer which does not suffer from contamination or drift due to vapor impurities such as glycol, methanol, amines, hydrogen sulfide, or mercaptans.
The analyzer works by shining a laser beam through the sample cell. The laser beam is selected to interact only with the measured compound, creating an absorption signal. The higher the concentration of H2O the greater absorption of light and the stronger the corresponding absorption signal. Spectrum Software analyzes these absorption peaks to produce very accurate and repeatable measurements. Since the calculation is a direct, fundamental measurement, the amount of H2O present can be measured in real-time.

HEATED SAMPLE CONDITIONING |

|
The P53 Heated Sample Conditioning System ensures performance of gas analyzer by delivering a heated sample through patented technology to the analyzer. This avoids costly errors resulting from hydrocarbon dew point drop out by the maintaining at least 30ºF above the expected hydrocarbon dew point. |
The gas sample is heated inside of the regulator before and after the pressure is reduced eliminating hydrocarbon liquid condensation caused by the Joule Thomson effect during the pressure reduction. |
