Product Description

NAKAKITA NSPS 732 Pressure Switch

The NAKAKITA NSPS 732 is a robust and reliable pressure switch designed for demanding industrial and marine applications. Manufactured by Nakakita Seisakusho, it is commonly used for monitoring and controlling pressure in various systems such as lubricating oil, fuel oil, cooling water, steam, and compressed air lines. Known for its durability and accuracy, the NSPS 732 features a compact design and is built to withstand harsh environments, often found in ship engine rooms and industrial plants. It typically utilizes a microswitch mechanism activated by pressure changes acting on a bellows element.
