Page 4: Machine Condition Tester T30
Evaluated vibration analysis Basic, Logger and Expert versions Machine Condition Tester T30 is available in three different versions: Basic, Logger and Expert. ”Basic” measures vibration severity, shock pulses, speed and temperature. It has no data logging functions – measuring results are recorded manually. It can be set to continuous measurement but does not record the results shown on the display. -

A BNC connector receiving vibration transducer. The instruments can monitor the connected SPM transducer type, e. g. a shock pulse transducer with or without transducer matching unit TMU, and react accordingly. In data logger mode and for long-time recording, three transducers can be simultaneously con- nected: SPM, VIB, and either temperature or tachometer probe. -

To leave this mode, disconnect the probe. For SPM and VIB, you have to input basic data. For this, you press the SET key and move the cursor with RIGHT/LEFT to the number you want to change. UP/DOWN changes the number, ENT saves and allows you to start a reading with the M key. -
Page 13: Record Keeping And Measuring Intervals
If you do not have Condmaster ® Pro, you can use an SPM follow-up form for recording shock pulse and vibration readings. Bearing and vibration condition should be measured at regular intervals of 1 to 3 months while machine condition is normal. -

Page 15: Spm Measuring Points
SPM measuring points The rules for the selection of SPM measuring points have a very practical purpose. We are trying to catch low energy signals which are getting weaker the farther they travel and the more they are bounced about inside a piece of metal. We know that they lose strength when they cross over from one piece of metal to another (oil between the pieces helps). -
Page 16: Shock Pulse Transducer With Probe
Neoprene, 110° C (230° F) Shock pulse transducer with probe All three types of shock pulse transducers are connected to the TNC connector marked SPM. The choice of transducer type depends on how the measuring point is prepared. For systematic shock pulse monitoring, SPM recommends the use of installed adapters and quick connect transducer wherever possible. -
Page 17: Transducer With Quick Connector, Terminal
Use a measuring cable to connect instrument and terminal. Check that installed transducers and adapters are properly mounted (see the instruction on SPM installations) and in good condition. You cannot expect a useful signal by attaching the quick connect transducer to a rusty lump of metal, or from a transducer that is rolling on the floor on the other side of a partition. -
Page 18: Measuring Points, Examples
Measuring points, examples The following two pages show measuring points and possible adapter or transducer installations. How to install measuring equipment is described in the SPM installation manual. Through hole for long adapter Figure A shows how a measuring point beneath a fan cover can be reached with a long adapter, through a hole in the cover. - Page 19 Adapters should be fitted with protecting caps. Mark the measuring points Measuring points for the probe transducer should be clearly marked with SPM measuring point markers. To get comparable readings, one must always use the same measuring point.

Page 20: Spm - Shock Pulse Measurement
SPM - shock pulse measurement The Shock Pulse Method for bearing condition monitoring (SPM) was developed for measuring rolling bearings. This is a summary of some important facts needed to understand the basic input data for bearing monitoring as well as the nature and use of the shock pulse transducers. -
Page 21: The Dbm/Dbc Technique
SPM Instrument AB • Box 504 • S-645 25 Strängnäs • Sweden Technical data are subject to change without notice. -
Page 22: Normalized And Unnormalized Readings
T30 has to be programmed with shaft diameter (in millimetre or inch) and rotational speed (in rpm). The T30 will then calculate the initial value dBi, the starting point of the condition scale for a particular bearing. You can also input the dBi directly. The condition scale is graded in normalized shock values, dBn. -
Page 23: Input Data
(B). For a normalized reading of bearing condition with a T30, you need the initial value dBi. Given the rotational speed (rpm) and the shaft diameter d, the T30 will calculate and display the dBi. The figure under (B) shows the setting when you input the rpm and the shaft diameter (here in mm). -
Page 24: Spm Measurement
- good (≤ 20) SPM measurement Back in the SPM menu, you can connect the transducer to the measuring point and press the M key to start a measurement. It takes approx. 2 - 10 seconds, during which the connected transducer type is displayed: PROBE for hand-held probe, TRA for the quick connect transducer and the standard 40000 transducer, TMU for a transducer matching unit in the transducer line. -

Page 26: Different Shock Pulse Patterns
F A sudden drop in the shock pulse level is suspicious. Check your measuring equipment. If the reading is correct, you may have a slipping bearing ring. SPM Instrument AB • Box 504 • S-645 25 Strängnäs • Sweden Technical data are subject to change without notice. -
Page 27: General Remarks On System Planning
As with any condition evaluation method, there are borderline cases and exceptions from the norm. In a few cases, SPM measurements can be more difficult because of low rpm and low or irregular load, interference from other shock pulse sources, or very rapid damage development. -
Page 28: Measuring Range
High speed bearings: The T30 accepts max. 19 999 rpm, 1 999 mm shaft diameter, and a dBi of 40. The upper part of table in figure 3 contains examples of possible combinations of shaft diameter and rpm giving a maximum dBi of 40. -
Page 29: Create Acceptable Measuring Conditions
If the interference level is persistently higher than the shock level that would be caused by bad bearing condition (35 to 40 dB above the dBi), do not try to monitor the bearing. SPM Instrument AB • Box 504 • S-645 25 Strängnäs • Sweden Technical data are subject to change without notice. -

Page 37: Typical Shock Pulse Patterns From Rolling Bearings
Bearings with dBm values in the yellow zone should be measured more frequently, to determine if their condition is stable or deteriorating. SPM Instrument AB • Box 504 • S-645 25 Strängnäs • Sweden Technical data are subject to change without notice. - Page 38 Periodic bursts are a typical interference signal, caused by rubbing between machine parts, e.g. shaft against bearing housing or seal. The burst occurs at an rpm related frequency. SPM Instrument AB • Box 504 • S-645 25 Strängnäs • Sweden Technical data are subject to change without notice.
