Product Features
Non contact measurement: does not come into contact with the rotating shaft, suitable for applications where the shaft may be contaminated or damaged.
High precision: It can provide accurate speed measurement results with an accuracy of ± 0.1%.
Band width: capable of measuring speeds within the range of 0 to 5000rpm.
Strong anti-interference ability: The measurement coil has high output and low impedance, enabling the sensor to effectively resist interference.
Durable and sturdy: Designed to withstand harsh industrial environments.
Application field: Suitable for measuring the casing vibration of rotating machinery such as steam turbines, gas turbines, water turbines, compressors, pumps, fans, etc. It is a commonly used sensor for MMS6000 and MMS3000 rotating machinery monitoring and protection systems.
