SHINKAWA Sensor Technology, Inc.
We are a manufacturer specializing in vibration surveillance devices
We were a development and manufacturing division of Shinkawa Electric Co., Ltd., which provides measurement and control solutions. We make use of technology cultivated over many years to provide products and services related to displacement and vibration sensors, vibration monitoring, and analysis and diagnostic systems. We were split from Shinkawa Electric Co., Ltd. in 1994 and started doing business as a specialized manufacturer of vibration monitoring instruments. We are determined to make rapid progress in further technical development and quality improvement. Our turbine supervisory instruments are one of our main product lines. These products use various types of sensors and provide a wide range of functionality such as condition monitoring, analysis, and diagnosis. They are extensively used for turbines, and also for large rotating machines and other important machinery. Displacement sensors are another of our main product lines. They are widely used in special areas including inspection cars for the Shinkansen bullet train services, rocket engines, nuclear power generation, semiconductor manufacturing, and magnet bearings. They are extensively used as feelers for various industrial machines and also for testing and research. We are working on developing new creative products based on outstanding sensor and analysis and diagnosis technologies. We are further expanding the fields of application of our technologies.

You can select from four types according to your use conditions and applications. - e-SWiNS (ISA 100) [2.4 GHz wireless sensing system] Wireless sensing system conforming to ISA 100 standards and intrinsic safety. These products are optimal for general-purpose mechanical vibration measurement and diagnosis in explosion-proof environments. - ZARK & Machine Dossier [Cloud-based mobile vibration monitoring system] We have realized a new form of condition monitoring by adopting battery-type wireless vibration sensors and centrally managing data with cloud services. It can be easily installed and allows vibration monitoring to be performed immediately. It also can reduce labor and costs. * Targets of rotating machine condition monitoring - Vibration: Shaft vibration (vibration of rotors) and casing vibration - Axial position: Axial position of the rotor in the vicinity of thrust bearings - Eccentricity: Shaft deviation (degree of bending) - Elongation: Elongation due to thermal expansion of the casing - Difference in elongation: Difference in elongation due to relative thermal expansion difference between the casing and the rotor - Number of rotations: Number of rotations of the rotor - Phase reference: A signal that serves as the reference for a vibration phase angle of a pulse per rotation - Valve aperture: A value according to the opening of a governor valve
