Perseus™ industrial flow switches

are known for their exceptional toughness and reliability, making them some of the most reliable switches available. These flow switches are specifically developed for various applications, including hydraulics, air, water, gases, chemicals, fuel oil, refrigerants, and more.

     With their robust housing and proven long-term reliability in harsh environments, Perseus™ industrial flow switches are an ideal choice for OEMs involved in the construction of pumps, compressors, gas turbines, diesel engines, and similar equipment.

     Whether these flow switches are exposed to waves crashing over them, being used as a step by engineers, or accidentally knocked by contractors with scaffolding, they are designed to withstand such conditions and maintain their functionality.

General Features:
     - Switch Configurations: You have the flexibility to choose between 1 x SPDT microswitch or 2 x SPDT microswitches for DPDT switching or adjustable deadband or dual independent switching. This allows you to configure the switch based on your specific requirements.
     - Internal Adjustment Scale: The flow switches are equipped with an internal adjustment scale, enabling precise and customizable flow measurement and control.
    - Housing Material: The switchcase is constructed using either 316 stainless steel or black anodized aluminum, ensuring excellent durability and protection. The housing meets IP66 and IP67 standards, indicating resistance to dust and water ingress.
     - SIL 2 IEC 61508 Suitability: The reliability and safety of Perseus™ industrial flow switches are proven and documented, with a SIL 2 rating according to IEC 61508 standards.

Perseus™ flow switches (Flameproof / Intrinsically Safe)

are available in flameproof Ex d and intrinsically safe Ex ia configurations, making them suitable for use in hazardous areas with hydraulics, water, sea water, chemicals, fuel oil, and other liquids.

     Designed with multiple switch configurations, robust housing, and proven long-term reliability (SIL rating) in tough environments, these flow switches are particularly well-suited for OEMs working on applications such as A/C units, chilling, heating and ventilation systems, radiator systems, and more.

     You can find these flow switches in oil & gas and petrochemical facilities worldwide, and they are commonly installed in desalination plants as well.
