Overview of the Nagano Keiki CD75 Explosion-proof Pressure Switch
Designed for Hazardous Environments (Focus Keyword Included)
The CD75 is a durable explosion-proof pressure switch developed for industrial applications where ignition risks must be minimized. Its robust construction allows safe operation in environments containing combustible gases or vapors. Suitable for both liquids and gases—such as air, water, oil, or chemical fluids—the CD75 brings stable performance across multiple industrial sectors.
Typical Applications
Chemical plants / Petrochemical facilities
Oil & gas processing
Shipbuilding and offshore systems
Hydraulic and pneumatic equipment
Water treatment, fluid control, and pipeline systems
Key Features and Technical Strengths
1. Adjustable Deadband for Precision Control
The CD75 allows fine-tuning of switching performance through an adjustable deadband. This capability supports accurate pressure monitoring tailored to each application, enabling stable system performance and optimized operational safety.
2. High Vibration Resistance
Built using a double snap-action mechanism with a specialized spring system, the CD75 is engineered to withstand vibration and shock. This makes it suitable for direct mounting on industrial machinery, hydraulic equipment, and high-demand process systems.
3. Corrosion-resistant Materials (SUS316 / SUS316L)
For enhanced durability, all wetted parts are made of SUS316 or SUS316L stainless steel, providing excellent corrosion resistance. This ensures long service life when handling chemical fluids, seawater, or other aggressive media.
4. Wide Pressure Range and Stable Accuracy
The CD75 supports a wide selection of pressure ranges, making it adaptable to diverse systems. With high accuracy and repeatability, it meets the requirements of process control, safety monitoring, and critical industrial applications.
5. Flexible Electrical Configurations
The device offers various micro-switch configurations and multiple connection thread types. This flexibility makes integration into existing systems efficient and cost-effective, supporting different engineering standards and regional installation requirements.
