Differences in speed sensors: Hall, magnetoelectric, eddy current
Thread Content
I haven’t been using this measuring instrument for long, and now I’m a bit confused about how to measure speed. Can speed measurement be done using photoelectric, magnetoelectric, eddy current, Hall… methods? Is that the correct way to categorize them? Also, each manufacturer gives slightly different descriptions; I’m not sure if they refer to the same category. The Bentley proximity sensor belongs to the eddy current type; Attek offers both active and passive versions, so which category does it fall into? There are also other classifications like magnetoelectric ones, which make things a bit confusing.
Magnetoelectric sensors come in powered and passive types; the most commonly used in field applications are passive magnetoelectric sensors and eddy current sensors
Are sensors and secondary meters from different manufacturers compatible with each other?
