Exceptional Flame-Proof ConstructionBuilt with cast aluminum or steel enclosures, these flow switches are designed to meet flame-proof standards, providing safety in explosive or hazardous atmospheres. Their ATEX II 2G Ex d IIC T6 Gb rating offers peace of mind when installed in industrial environments where flammable substances may be present.
Wide Compatibility and Automatic OperationEngineered for compatibility with water and non-corrosive liquids, these paddle-type flow switches integrate easily into industrial processes. Automatic SPDT micro switches ensure reliable detection of flow rates from 1.0 to 8.0 m/s, enabling seamless process automation and control.
Reliable Design and Superior ProtectionEquipped with IP65/IP66 ingress protection, robust PG cable gland or screw terminal connections, and a polished or coated finish, these switches resist dust and water ingress. Their mechanical life exceeds 1,000,000 operations, highlighting their durability and long-term performance in challenging environments.
FAQs of ATEX certified Paddle type Flow Switches:
Q: How do ATEX certified paddle-type flow switches function in hazardous environments?
A: These flow switches utilize flame-proof enclosures and ATEX certification to operate safely in environments where explosive gases may be present. The paddle mechanism detects liquid flow, activating a micro switch that sends a signal to your control system.
Q: What types of liquids are compatible with these paddle-type flow switches?
A: The switches are compatible with water and non-corrosive liquids, making them suitable for a variety of industrial process applications where chemical resistance is not a primary concern.
Q: When should I use an ATEX certified flow switch over a standard model?
A: ATEX certification is essential when installing equipment in hazardous environments, such as chemical plants or refineries, where explosive atmospheres could occur. The additional certification ensures compliance with safety regulations and minimizes risk.
Q: Where can these flow switches be installed?
A: They can be mounted inline using BSP or NPT threaded connections anywhere within a water or non-corrosive liquid pipeline system, provided the ambient temperature ranges between -20C and +60C.
Q: What is the electrical connection process for these devices?
A: Electrical connections are made via screw terminals or PG cable glands, providing secure and reliable wiring. Ensure proper insulation resistance (100M at 500VDC) during installation for safety and performance.
Q: How does the automatic switching feature benefit industrial operations?
A: The built-in SPDT micro switch delivers rapid response (under 1 second), allowing for automated control and immediate alerting in case of flow deviations, helping protect equipment and maintain process efficiency.
