The eddy probe SKFCMSS 68-070-00-12-10 is used to measure radial or axial shaft motion. It is mounted through or to the side of a bearing cap and observes the shaft’s movement relative to its mounting position. An eddy probe system comprises a probe, a driver (oscillator demodulator) and an optional extension cable. Eddy probe systems have excellent frequency response. They have no lower frequency limit and are used to measure shaft axial position as well as vibration.
