Unlike eddy-current probes that require -10 VDC targets for gap voltage validation, this sensor outputs a signal based on the casing vibration intensity. To maintain measurement fidelity, ensure the mounting surface is machined flat to minimize high-frequency attenuation. Cross-talk suppression is achieved by utilizing shielded cabling and preventing cable loops that can act as induction antennas for electromagnetic noise, which would otherwise obscure low-frequency vibration data required for monitoring machine health.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can this sensor be mounted on any surface orientation?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The piezo-velocity sensor is omnidirectional regarding gravity, but the mounting surface must be rigid and free of paint or corrosion to ensure accurate transmission of casing vibration.\u003c\/p\u003e\n\u003cp\u003eQ: Is there a specific torque requirement for the 1\/4-20 UNC stud?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The sensor must be torqued to a value that ensures a secure, high-frequency coupling with the machine casing. Avoid over-torquing, which may strip the threaded interface or induce stress on the internal sensor housing.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMachine the mounting surface to a flat finish to guarantee full contact area for the transducer base.\u003c\/li\u003e\n\u003cli\u003eApply a thin layer of silicone grease to the mounting interface to improve high-frequency energy transfer if the surface finish is not ideal.\u003c\/li\u003e\n\u003cli\u003eInstall the sensor using the 1\/4-20 UNC stud.
