Eddy current sensors
- Eddy current path sensors are also very suitable for speed sensing
- It is possible to measure on various wheels with grooves, teeth, holes, made of various metal materials...
- Measurement is also possible directly on the shaft with a piece of copper foil glued
- The measurement is less sensitive to the shape and accuracy of the teeth and the cleanliness of the environment
- The output signal from the sensor (or converter) has the shape of pulses influenced by the shape of the teeth, the material of the measuring wheel or the setting of the air gap and usually requires further processing by a suitable transmitter
- Suitable are, for example, the A 3311 transmitter (it also contains a sensor converter), or monitors A6500-UM, A 6312
- This type of sensors is also used by the SIL3 tachometer A 6300 SIS, and its predecessors epro DOPS and MMG1000TS
