Wuxi Houde | 8500B-ZS81 Overspeed Plug-in Monitoring Card Module

Overview:

8500B-ZS81 overspeed plug-in monitoring card module adopts an intelligent speed monitoring and protection instrument with a single-chip microcomputer as the core, equipped with a magnetic resistance speed sensor and a gear speed sensor, which can measure the speed and linear speed of the axle, gear, and rack of various rotating machinery. It is suitable for the system design and use of TSI of rotating machinery devices and can be widely used in power, machinery, chemical industry, metallurgy and other industries. It provides multiple parameter measurements and early fault prediction for the safe operation of rotating machinery.
