The Cassper CD-1C is a Nason adjustable high-pressure switch designed for industrial applications requiring precise pressure monitoring and control. This field-adjustable switch delivers reliable performance across multiple pressure ranges, from 10 PSI to 7500 PSI, with set point tolerance of ±5 PSI or 5%. The unit operates across a wide temperature envelope of -20°F to +220°F (-29°C to +104°C) and is rated for 1 million cycles, making it suitable for demanding hydraulic and pneumatic control systems.
