The S100 Series is a cost-effective and reliable dust monitoring solution designed to detect changes in dust levels within gas flow systems. The S100 provides real-time, continuous monitoring for leaking or broken filters in ducts with a diameter of less than 1 meter. Engineered for industrial environments, this robust monitor features a rugged IP66-rated design, ensuring durability in harsh conditions. The S101/S101 Ex models include two relays for dust alarms, while the S103/S103 Ex offers an active, isolated 4–20 mA output for seamless integration. With a fast response time, selectable detection speeds (FAST, MEDIUM, SLOW), and a self-teaching Auto Setup function, the S100 Series allows for easy commissioning and precise monitoring. Its highly visible green, yellow, and red LED indicators provide at-a-glance dust level status, while IECEx and ATEX certifications ensure safe operation in Zone 22 environments inside ducts and ambient air.
