Model SA-XDS gas detection systems are designed to detect a wide range of gases in ambient air. The systems are scalable and can be configured to monitor volatile organic compounds, toxic gases, oxygen, and combustible gases in ambient air. Select from one of four system configurations: Model SA-2DS 1-2 sensors, Model SA-4DS 1-4 sensors, Model SA-6DS 1-6 sensors. Specific gas type is determined by installing Safeguard Analytics Model SA1 smart sensor modules. Each smart sensor module stores gas type, range of sensitivity, and the last zero and span calibration data points facilitating plug and play versatility for a wide range of gas detection applications. Sampling is via diffusion at the point of installation.
All system components are mounted in a NEMA 4X weatherproof enclosure suitable for installation in areas classified as non-hazardous locations. Model SA-XDS gas monitors feature non-intrusive calibration using a small magnet. A MODBUS slave port serves as a gateway to cloud-based data acquisition and data analysis portals.
Model SA1 Smart Sensor Modules
Model SA1 smart sensor modules are designed to detect and monitor various gases in ambient air. The modules consist of a target specific gas detection sensor and a microprocessor-based signal conditioning circuit. Both are housed in a metallic enclosure fitted with gold plated connecting pins. The “Smart Sensor Module” is factory programmed for a specific gas and range of sensitivity. On power up the gas type, measurement range and previous zero and span calibration data points are read by the control system facilitating a fully automated startup. The modules can be used with any of Safeguard Analytics gas detection systems and control transmitters.
