The SST GT810 Toxic Gas Sensors are used to determine the concentration of gas accumulated in a protected area and transmit this information to a central control point.
The SST GT810 use an electrochemical fuel cell with a patented diffusion barrier. Located inside a stainless steel flameproof housing, the sensing element is exposed to the detected gas through a sintered stainless steel flame arrestor. The three electrode toxic gas micro fuel cells are designed to be maintenance free and stable over long periods of time. They use 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 non-condensing.
Each SST model GT810 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.
The SST GT810 is suitable for the most demanding applications. A large body mass insures excellent vibrational characteristics when used for offshore use.
