The KD series eddy current sensor is a non-contact measurement sensor from Yes, which can accurately measure the relative position of the measured object (must be a Yes metal conductor) and the probe end face. The voltage signal output by the sensor is proportional to the distance between the probe end and the measured conductor.It can be used for both static (displacement) and dynamic (vibration) measurements.It is mainly used for measuring parameters such as shaft displacement, shaft vibration, and shaft speed of rotating machinery, and can effectively monitor and protect equipment.

Test conditions |
Tested material: 45# steel (equivalent to AISI4145 steel);ambient temperature: 20±5℃;relative humidity: <80% |
||
|
Application |
Dynamic and static displacement;mechanical fault detection;non-contact displacement measurement |
||
|
Connecting cables |
Probe cable + extension cable = 5 meters or 9 meters （customizable) |
||
|
Eddy current calibration bench |
The calibration length is 80mm, which is used to detect the relationship between the change in the static length of the sensor and the output voltage value. |

|
Notes |
The sensitivity interchangeability error refers to the comparison between any component after interchange and the standard sensitivity. |
