While PeakVue is very useful for providing an early indication of impact-related faults in rolling-element bearings, there are many general applications where a lower-frequency measurement is more appropriate. Also, virtually all vibration analysts are very familiar with the Overall Velocity measurement and use it as part of their existing vibratio[...]

PeakVue advisory levels Figure 5-4: These are the equations that govern this curve: These, however, are generic limits. They are provided as a starting point and these values (for a 3600 RPM machine) are used as the default alert thresholds by the[...]

Note The appropriate alerts for a given machine will be a function of its design, service, and turning speed. Utilizing the embedded PeakVue technology, the CSI 9420 identified developing problems at a couple of test sites during early field trials. In both cases, the problem was not visible with conventional low-frequency analysis. The following e[...]

The defective bearing was removed and Figure 5-7 shows the developing problem that was the source of the impacting. After replacing the bearing, the PeakVue vibration is significantly reduced, as shown in Figure 5-8 , indicating that the problem has been resolved. Defective bearing Figure 5-7: Velocity, PeakVue, and temperature MHM-97408, Rev 15 97[...]

Motor - OH after the bearing is replaced (PeakVue) Figure 5-8: 5.3 Temperature The levels at which to set temperature alerts depend on a number of factors including the specific process, the operating environment, and the characteristics of the equipment being monitored. This section provides some generic guidelines, given some knowledge of the var[...]

5.3.1 Relative temperature monitoring The recommended generic guidelines for setting the thresholds based on the relative change are: T Advise = 10°C increase T Maintenance = 15°C increase T Failed = 20°C increase Assuming that the ambient temperature is 25°C, when operating at steady-state, you have determined that the normal temperature at th[...]

6 Accelerometer EMI and RFI considerations The CSI 9420 uses an accelerometer to measure vibration. The process involves a piezoelectric element, which produces a time-waveform with voltage amplitude proportional to acceleration. The input bandwidth of the measurement is approximately 20 kHz. This waveform is then digitized and analyzed within the [...]

Frequency spectrum representation of the signal with interference. Accelerometer EMI and RFI considerations 102 MHM-97408, Rev 15[...]

6.1 Mitigate interference The following are four basic things you can do to reduce EMI and RFI on measurements: • Use a shorter cable, if possible. For more details, see Section 6.1.1 . Note The leads on the sensor cables, as delivered, are specially prepared for ease of installation. Before attempting to cut the cables, be aware that cutting cab[...]

Figure 6-2 shows how to run the accelerometer through a conduit that is grounded on both ends. As a general rule, the transmitter housing itself is grounded through the base where it is mounted. Since the conduit is electrically connected to the transmitter housing, this effectively grounds the conduit at the transmitter end. Grounding the conduit [...]

6.1.3 Install ferrites Note The accelerometers are shipped with ferrites installed at the accelerometer end. To maintain the optimum performance of the accelerometer, do not remove the ferrites. To meet the stated performance criteria, the standard accelerometer cable has two (2) ferrites installed. These are Steward ferrites (P/N 28B0355-000), wit[...]

The armor-jacketed accelerometer cable has one ferrite installed. It is a Steward ferrite (P/N 28B0672-000), which provides 245 Ω of reactance at 100 MHz.

From a compliance perspective, you do not need to install the ferrites if the cable is in a ferromagnetic conduit (such as galvanized steel) because this type of conduit provides additional shielding. Note that the conduit entry of the device is ½ inch NPT. If you install ferrites with a conduit, you will need a wider conduit ( ¾ inch NPT or M20)[...]

The ferrite in this example is Fair-Rite P/N 0431164281, which has a reactance that ranges from 28 Ω at 1 MHz to 310 Ω at 100 MHz and 240 Ω at 250 MHz. It supports a maximum cable diameter of 0.260 inch (6.6 mm). Effect of ferrites on interference Figure 6-10 compares two accelerometers in the presence of a high-intensity RF field (10 V/m). The [...]

Figure 6-10 also shows that ferrites provide a huge amount of RFI suppression and are needed to maintain measurement integrity in the presence of strong electromagnetic interference. Do not remove the ferrites installed on the accelerometer cables that are shipped from the factory, even if you mitigate interference using other methods. 6.1.4 Reduce[...]
