摘要：Device comprises a fixed detection assembly (50) capable of detecting anopening (40), which acts as a marker within a rotating body that includes a metallic disk

(36). The detector consists of a magnetic proximity sensor (52) and means (72) for testingthe correct operation of the sensor. The latter is arranged externally to the proximitysensor and has no direct electrical contact with it. The sensor (52) is typically an inductoror similar. Typically the tester for correct operation of the proximity sensor is a coilsurrounding the end of the sensor (52) and connected to a means for changing its statefor example by short circuiting it.
