After the debonding agent has set you can use an ordinary open end wrench if the accelerometer has a hex base or square base or the supplied removal tool for teardrop accelerometers After attaching either use a gentle shearing or twisting motion by hand only to remove the sensor from the test structure 4 3 MAGNETIC MOUNT Magnetic mounting provides a convenient means for making quick portable measurements and is commonly used for machinery condition monitoring predictive maintenance spot checks and vibration trending applications NOTE The correct magnet choice and an adequately prepared mounting surface are critical for obtaining reliable measurements especially at high frequencies Poor installations can cause as much as a 50 drop in the sensor frequency range Not every magnet is suitable for all applications For example rare earth magnets are commonly used because of their high strength Flat magnets work well on smooth flat surfaces while dual rail magnets are required for curved surfaces such as motor housings and pipes In the case of non magnetic or rough surfaces it is recommended that the user first weld epoxy or otherwise adhere a steel mounting pad to the test surface This provides a smooth location for mounting and a target to insure that subsequent measurements for trending purposes are taken at the same location Sensor stud mounts to top surface flat and smooth 4 Ll Flat Magnet Dua

In fact the uncertainty may be as high as 3 or 4 for frequencies 10 Hz or gt 2 kHz Since large sensors may affect high frequency accuracy verify that the test sensor does not mass load the reference standard Validate your calibration system with another accelerometer prior to each calibration session Check with the manufacturer for exact system specifications 8 5 CONCLUSIONS Without an adequate understanding of dynamics determining what when and how to test a sensor is a difficult task Therefore each user must weigh the cost time and risk associated with self calibration versus utilizing the services of an accredited laboratory 9 0 SERVICE See the supplement sheet contained in this manual for information on our warranty service repair and return policies and instructions When unexpected measurement problems arise call our 24 hour SensorLine to discuss your immediate dynamic instrumentation needs with a factory representative Dial 716 684 0001 PIEZOTRONICS VIBRATION DIVISION 3425 Walden Avenue Depew NY 14043 2495 USA Vibration Division toll free 888 684 0013 24 hour SensorLine 716 684 0001 FAX 716 685 3886 E mail vibration pcb com Website www pcb com A PCB GROUP COMPANY ISO 9001 CERTIFIED A2LA ACCREDITED to ISO 17025 2002 PCB Group Inc In the interest of constant product improvement specifications are subject to change without notice PCB and ICP are registered trademarks
