INTRODUCTION

The NAGANO KEIKI Pressure Sensor Switch Gauge is a precision pressure measurement and monitoring device widely used in marine automation and engine room applications. Manufactured by Nagano Keiki Co., Ltd., Japan, these instruments are recognized globally for their reliability, accuracy, and long service life in demanding marine environments.

Pressure monitoring is one of the most important functions onboard ships. Critical systems such as main engines, auxiliary engines, fuel oil systems, lubricating oil systems, cooling water systems, hydraulic systems, boilers, and air systems depend on accurate pressure measurements for safe and efficient operation.

The NAGANO KEIKI Pressure Sensor Switch Gauge continuously measures system pressure and transmits electrical signals to monitoring and alarm systems. This allows marine engineers to detect abnormal conditions before they develop into serious equipment failures.
