The Hughes brass insertion flow switch is a mechanical flow detection device designed for monitoring fluid movement in industrial systems. This robust flow switch is particularly suited for use in hazardous environments, being ATEX approved for operation in Zone 1 and Zone 2 explosive atmospheres. The switch body is constructed from durable brass, providing excellent corrosion resistance for water-based applications and compatibility with non-aggressive liquids. The mechanical paddle design provides a simple, reliable flow/no-flow indication.

Key Features

• ATEX Zone 1 & 2 Certified: Suitable for use in explosive atmospheres with flammable gases, vapors, or dusts.
• SPDT Contact Function: Provides flexibility for control system integration, allowing both normally open and normally closed configurations.
• IP65 Enclosure: Dust-tight and protected against low-pressure water jets, ensuring reliable operation in harsh industrial environments.
• Brass Construction: Offers good corrosion resistance and durability for water-based and non-corrosive liquid applications.
• Threaded Connection: Designed for easy in-line installation via standard pipe threads.

Applications

This flow switch is ideal for flow/no-flow detection in industrial applications, including:

• Fluid pump protection (dry-run prevention).
• Water inlet monitoring for process equipment.
• Air compressor flow control.
• Cooling water circuits and heat exchangers.
• Industrial automation systems requiring flow status feedback.
