Application Note
SpectraSensors SS2000 Single Channel Analyzer for CO2 is extremely reliable and tailored for the needs of the natural gas industry. The sensor measures gas using a patented Tunable Diode Laser Diode (TDL) to determine the concentration of the gas without coming into physical contact with the stream.
RAPID RESPONSE TIME The SS2000 analyzer takes four measurements per second with a laser and detector and immediately averages the results. Because there is no contact with the gas, real-time measurements are not hampered by wet-up or dry-down times as with surfaced-based sensors.
RELIABLE Trustworthy measurements are vital to natural gas pipeline and processing companies. Independent studies have proven that the SS2000 results are highly correlated with those of chilled mirrors. However, chilled mirrors require skilled experts to operate and the results are highly scattered (large standard deviation).
Uncertain measurements can be extremely costly. Additional processing of dehydration costs, upset conditions, shut-ins and inconsistent process results may be caused by sensors that do not perform properly. The SS2000 is the first to offer truly reliable measurement and simple operation.
LONG LIFE The TDL sensor does not come into contact with the sample gas stream. The result is a sensor which does not suffer from contamination or drift due to vapor impurities such as glycol, methanol or amines.
LOW COST OF OWNERSHIP Operating costs are dramatically reduced by eliminating the cost of consumables, extra sensor heads, labor and overhead associated with excessive maintenance.
The SS2000 dramatically reduces intangible but real costs associated with unreliable gas measurements. By eliminating added processing steps, detecting poor gas quality and the possibility of costly damage to equipment that can result from sensors that produce incorrect data.
