The SST GT820 Oxygen Deficiency/Enrichment Sensor is used to determine the concentration of oxygen present in a protected area and transmit this information to a central control point.
The SST GT820 uses an electrochemical fuel cell with a patented diffusion barrier as the sensing element. Located inside a stainless steel flameproof housing, the sensing element is exposed to the detected gas through a sintered stainless steel flame arrestor. The oxygen fuel cell is designed to be maintenance free and stable over long periods of time. It uses a capillary diffusion barrier technology which results in a direct response to volume concentration. A high reserve of electrochemical activity insures a long life and excellent temperature stability. The performance is relatively unaffected by humidity, provided that conditions are noncondensing.
Each SST GT820 includes a high reliability loop powered electronic Transmitter. This transmitter converts the signal from the fuel cell element to a standard 4-20 mA signal. This signal may be connected to a suitable SST NOVA-5000 Oxygen Detection Module, or to any other device with a standard 4-20 mA input.
The SST GT820 is suitable for the most demanding applications. A large body mass insures excellent vibrational characteristics when used for offshore use. Corrosion resistant materials permit uses in most environments.
