Differential Pressure Switch TETROSWITCH DP

Product catalog summary

Overview: The TETROSWITCH DP is a series of differential pressure switches designed for low and high static pressure applications across various industries including chemical, petrochemical, machinery, food, pharmaceutical, and both onshore and offshore environments. The switches have setting ranges from 0 to 16 bar.

Technical Characteristics:

Material and Construction: The case and cover are made from stainless steel (St. St. series 300) with a bayonet type ring. The protection degree is IP65 (EN60529/IEC529), NEMA 4.
Electrical Wiring: Features an internal terminal board with one internal and one external ground terminal.
Sensing Element: Diaphragm made from materials such as AISI316L, Monel, and Hastelloy C276.
Connections: Flanges and process connections are made from AISI 316, with options for ½” NPTM or BSP connections.
Temperature Limits: Ambient temperature ranges from -30°C to +90°C, and fluid temperature ranges from -30°C to +150°C.
Compliance: Constructed according to ATEX directive 94/9/EC for intrinsically safe circuits and PED directive 97/23/EC upon request.

Options and Accessories: Various diaphragm materials (e.g., Hastelloy-C, Tantalum, Titan), mounting brackets, and degreasing for O2 service are available. Accessories include syphons, manifolds, and chemical seals.

Ordering Information: Specify model, micro switch type, setting range, process connection, cable entry, and any options or accessories.

Micro Switches (Table A): Options include silver and gold-plated contacts, with various configurations for resistive loads. Adjustable dead bands are available for certain configurations.

Setting Ranges (Table B): Detailed ranges are provided, with specific static pressure and dead band values for different configurations.

Process Connection and Cable Entry: Various types and codes are available for process connections and cable entries, including BSP and NPT options.

Weight and Dimensions: The unit weighs 5.5 kg.
