Industrial Applications

1. Intrinsically Safe Fieldbus Integration in Chemical Reactors

Integrating field instruments (e.g., temperature, pressure, level sensors) in highly volatile chemical reactor environments (Zone 0/Div. 1) that require intrinsic safety to prevent ignition. The FieldBarrier connects these instruments to the control system via FOUNDATION Fieldbus H1 or PROFIBUS PA, ensuring data integrity and safety.

Problem Solved

Prevents potential ignition in explosive atmospheres (e.g., hydrogen, acetylene, carbon disulfide) by providing intrinsically safe power and data connections to field devices in Zone 0/Div. 1 hazardous areas, while allowing easy troubleshooting with integrated LEDs.

2. Field Device Connectivity for Offshore Platforms and Refineries

Providing robust and intrinsically safe connectivity for various sensors and actuators on offshore oil and gas platforms or in refinery process units where explosive gas mixtures are present (Zone 1/Div. 2). The aluminum housing and IP67 rating ensure durability in harsh marine or industrial environments.

Problem Solved

Enables reliable and safe communication for multiple field instruments in outdoor, potentially explosive environments (Zone 1/Div. 2) such as wellheads, storage tanks, and pipelines, protecting against faults and ensuring continuous operation in corrosive and humid conditions.

3. Hazardous Area Instrumentation for Solvent-Based Production

Interfacing process instrumentation in pharmaceutical facilities that handle flammable solvents during active pharmaceutical ingredient (API) production. The FieldBarrier's short circuit current limitation per output and Ex ia IIC certification are crucial for maintaining safety standards in potentially explosive atmospheres.

Problem Solved

Safely connects multiple intrinsically safe instruments in pharmaceutical manufacturing areas where flammable solvents create hazardous zones, preventing fault propagation and ensuring process control integrity without compromising explosion protection.
