Vibration sensor or measurement detector
Vibration sensors or measurement detectors having connecting cables ( 40 ) for electrical supply voltages and/or signal voltages are provided with a clamping or winding space ( 42 ) on the bottom of the sensor housing ( 10 ). One or more turns of the respective connecting cable is deposited with in the clamping or winding space when the sensors are screwed tightly onto a machine or the like. The connecting cable can have any optional azimuth angle relative to the sensor coordinates and is well protected against external, damaging mechanical effects.
1. Vibration sensor or measurement detector, comprising:
a connecting cable for at least one of electrical supply voltages and signal voltages,
a sensor housing with a clamping or winding space on a bottom of the sensor housing into which at least one turn of the connecting cable is receivable with the at least one turn lying in a single plane and the connecting cable emerging from the clamping or winding space to the outside in a tangential direction relative to the at least one turn of the connecting cable
wherein the sensor housing has both a winding space and a clamping space, wherein the clamping space is located radially outward of the winding space, and wherein the sensor housing is attachable to machinery to be monitored in a direction perpendicular to the single plane in which said at least one turn lies so that a portion of the connecting cable in the clamping space is clamped against the machinery as the sensor housing is attached to the machinery.
2. Vibration sensor or measurement detector as claimed in claim 1 , having an additional cable chamber which is located radially inside of the clamping or winding space.
3. Vibration sensor or measurement detector as claimed in claim 1 , wherein the clamping and winding space is dimensioned and configured to cause winding of the connecting cable in a single plane as the vibration sensor or measurement detector is mounted by screwing it in.
4. Vibration sensor or measurement detector as claimed in claim 3 , wherein the clamping and winding space is dimensioned and configured to protect the connecting cable against unintentional uncoiling by producing a predefined loading and deformation of the cable in a radial direction.
5. Vibration sensor or measurement detector as claimed in claim 1 , wherein the bottom of the sensor housing has an attachment mechanism by which the sensor housing is attachable to machinery to be monitored.
6. Vibration sensor or measurement detector as claimed in claim 5 , wherein the attachment mechanism comprises a threaded connecting pin.
7. Vibration sensor or measurement detector as claimed in claim 5 , further comprising a contact-making pin for delivering a signal voltage from the sensor or measurement detector to the connecting cable in said winding space wherein the contact-making pin extends in an attachment direction of the sensor housing.
8. Vibration sensor or measurement detector as claimed in claim 1 , further comprising a contact-making pin for delivering a signal voltage to the connecting cable in said winding space.
9. Vibration sensor or measurement detector as claimed in claim 1 further comprising a contact-making pin for delivering a signal voltage to the connecting cable in said winding space, said contact-making pin extending in said direction perpendicular to the single plane so as to make contact with the connecting cable as the sensor housing is attached to the machinery.
10. Vibration sensor or measurement detector as claimed in claim 9 , wherein the connecting cable is a coaxial cable having an inside conductor and an outside conductor, wherein the contact-making pin delivers a signal voltage from the sensor or measurement detector to the inside conductor and wherein the outside conductor makes contact with the sensor housing or an additional connecting element.
