Product Description

Adv Tech RFS-D-010EX Intrinsically Safe Hot Plug Flow Switch

The Adv Tech RFS-D-010EX Intrinsically Safe Hot Plug Flow Switch is a high-performance solution designed for reliable flow detection and monitoring in hazardous environments. Engineered to meet the demands of industries such as oil & gas, chemical processing, LNG terminals, and petrochemical plants, this switch combines advanced thermal dispersion technology with intrinsic safety certifications to ensure operational safety and precision. Its hot plug design allows for maintenance or replacement without interrupting the process, minimizing downtime while maintaining compliance with global standards like ATEX, IECEx, and SIL 2.

The RFS-D-010EX utilizes thermal dispersion (hot plug) technology to detect flow/no-flow conditions in liquids and gases, offering immunity to media viscosity changes and debris buildup. With an adjustable measurement range of 0.1–10 m/s for liquids and 0.5–30 m/s for gases, it adapts to diverse applications, including hydrocarbon pipelines, corrosive chemical dosing, and cryogenic fluid systems. The device provides multiple output options, including SPDT relay, 4–20 mA analog signal, or NAMUR interface, ensuring seamless integration with control systems for alarms, pumps, or valve automation.

Built for durability in extreme conditions, the RFS-D-010EX features SS 316L wetted parts and PTFE seals for corrosion resistance, alongside an IP67/NEMA 4X-rated aluminum alloy housing that withstands dust, water, and mechanical impacts. Its -40°C to +120°C (-40°F to 248°F) process temperature range ensures stability in harsh environments, from offshore platforms to arctic LNG facilities. The switch's intrinsic safety certification (ATEX/IECEx Zone 0/1) guarantees safe operation in explosive atmospheres, while FM and CSA approvals validate its suitability for North American hazardous locations.

Key design advantages include adjustable sensitivity for media-specific calibration, a <1-second response time with delay settings to filter turbulence, and LED indicators for real-time flow status visualization (red/green). The hot plug functionality enables live insertion and removal without process shutdown, enhancing maintenance efficiency. Installation flexibility is achieved through G1/2", G3/4" threads.
