The rotation speed sensor DF6101-005-100-01-03-00-00 is a high-performance sensor device in the field of industrial automation, focusing on the accurate measurement of the speed of rotating objects through the principle of electromagnetic induction. This sensor combines advanced technical design and precision manufacturing technology, and is widely used in various scenarios that require accurate monitoring of speed and vibration parameters, such as mechanical equipment status monitoring, turbine maintenance, etc. Below we will explore its working principle, characteristics and advantages from a technical perspective.

Technical core: electromagnetic induction principle

The core mechanism of this sensor is based on electromagnetic induction, using the interaction between magnetic materials and coils. The sensor integrates a magnetic steel (magnet) to generate a stable magnetic field, which passes through the path formed by the soft magnetic armature and the winding coil. When a rotating gear with ferromagnetic teeth approaches the sensor, its teeth and gaps pass alternately, causing periodic changes in the magnetic resistance in the magnetic field path. This change induces an AC voltage signal in the coil, and its frequency directly corresponds to the speed of the gear. For involute gears, due to the particularity of their tooth shape, the induced signal presents a nearly ideal sine wave form, which is conducive to accurate measurement.

Technical Specifications and Performance

Measurement Range: The sensor can measure amplitude up to 0-500 microns (peak-to-peak), and vibration intensity can be measured up to 0-50.0 mm/s (true RMS), not only limited to speed, but also covers the monitoring of equipment vibration intensity.

Frequency Response: Its frequency response range is 5-3000Hz, ensuring that a wide range of equipment speed monitoring needs from low speed to high speed can be covered.

Accuracy and Linear Error: The measurement accuracy reaches 0.5 level, and the linear error is controlled within ±0.5%, reflecting extremely high measurement accuracy.

Frequency Response Extension: The response frequency range is further extended to 1Hz to 10000Hz, enhancing the sensitivity to low-frequency vibration and high-frequency changes.

Installation Clearance: The recommended installation clearance is 1-4.5 mm, which is convenient for flexible installation according to the actual layout of different equipment.

Gear Compatibility: It is suitable for involute gears with module 2 to 4, with strong versatility and can be flexibly configured according to the number of teeth of the specific gear plate.

Speed ​​measurement accuracy: In terms of speed measurement, the measurement accuracy of ±1 revolution is guaranteed, which is quite accurate for most industrial applications.

Output signal: Provides 4-20 mA current output signal, with a maximum load resistance of 850 ohms, ensuring stable signal transmission and compatibility, suitable for long-distance signal transmission, and reducing interference.

Technical advantages and applications

The technical advantages of the DF6101-005-100-01-03-00-00 speed sensor are reflected in its high measurement accuracy, wide range of applications, flexible installation and compatibility, and excellent anti-interference ability. Through non-contact measurement, mechanical wear is reduced and the service life of the sensor is extended. Its application in vibration analysis and equipment status monitoring can effectively prevent equipment failures, reduce maintenance costs, and improve production efficiency. Especially in the health management of continuously running large-scale industrial equipment such as turbines, generators, pumps, etc., the sensor plays an irreplaceable role and provides solid technical support for the realization of intelligent manufacturing and remote monitoring.
