Non-contact type Vibration Sensors
The non-contacting displacement probe transducer systems are gap to voltage devices that measure static as well as dynamic distances between the probe tip and the observed target.The probe tip is constructed of polyphenylene sulfide, a high performance plastic, impervious to oil, water and many different chemical liquids.
The probe housing is made of stainless steel and the probe cable is concentric with PTFE isolation. The most common use is for shaft position and relative vibration measurement on rotating machinery.
The transducer detects in the return signal the strength loss for the eddy-currents generated in the observed surface and conditions the signal for linear voltage output. The probe-transducer system indicates the dynamic motion of the shaft relative to the bearing.
