Diffusion Monitoring Systems
Continuous Multi-Sensor Platform for a Wide Range of Applications
Model SA-XDS
Multi Sensor Diffusion Based Monitoring System
Highly configurable multi-gas monitoring controller that simultaneously displays the gas type, readings, and status for each channel of gas detection.
- Combustible Gases
- Toxics Gases
- Carbon Dioxide
- Oxygen Deficiency
- Volatile Organic Compounds
Designed for monitoring a wide range of gases in ambient air, SA-XDS systems utilize Smart Sensors, each with a combination of optional gas types, range of sensitivity and alarm levels. The system controller is equipped with an intuitive full-script Human Machine Interface (HMI) featuring a color LCD. On startup, the system controller automatically configures the installed Smart Sensors, identifying pertinent data for each sensor, such as serial number, gas type, sensitivity range, most recent zero and span calibration data points, and last calibration date. User interface is accomplished using a programming magnet and front-panel push-button switches. The system is housed in a rugged NEMA 4X weatherproof enclosure, ensuring durability and protection against environmental elements.
