Page 4: Description
Problems with bearings occur when there is a microscopic crack or flaw or when there is a breakdown in lubrication which leads to metal‑to‑metal interaction. The EXAMINER 1000 is designed to detect flaws or a lack of lubrication in bearings and gears at an early stage by measuring the high‑frequency impacts through acceleration... -

Page 7: Benefits Of Predictive Maintenance
Preventive Maintenance occurs when a machine, or parts of a machine, are overhauled on a regular basis regardless of the condition of the parts. While better than run to failure, preventive maintenance results in excessive downtime due to unnecessary overhauls and the excessive costs of replacing good parts along with worn parts. -
Page 8: Common Predictive Maintenance Measurements
(norm) indicates the current health of the machine. The EXAMINER 1000 measures the vibration of a machine while it is operating. Trending these measurements shows how a machine’s condition changes over a period of time. Analyzing these, along with other measurements, provide insight into the condition of the machine and which components may be wearing or failing. -

a loss of lubrication which induced the mechanical failure. If vibration increased first, followed by increased temperature readings, then a mechanical defect caused the lubrication failure. 6.3 Lube Oil Analysis (Ferrography) Monitoring oil condition warns of an increase in foreign substances, such as water, which can degrade the lubricating properties of the oil and cause bearing failures. -
Page 10: Selecting Measurements
Those mechanisms are: Stress: a force on the machine or components which deflects the part. Best measured in Displacement. The EXAMINER 1000 does not measure Displacement as it is a very low vibration frequency, below... -
Page 11: Selecting Measurement Intervals
Impact Forces: the result of fatigue. Impact forces are cyclical events which can be detected with Acceleration Enveloping. These are high frequency‑low amplitude events and a filter in the EXAMINER 1000 is set at 10-30 kHz to measure them. 7.3 Selecting Measurement Intervals... -
Page 12: Getting Started In Your Plant
In order to setup up a trending program you must collect data on the same point with the same measurement type at a defined interval. The EXAMINER 1000 is a helpful tool to collect this data. As an overall vibration meter with electronic stethoscope, the EXAMINER 1000 can be used as a stand‑alone device for the collection of vibration data for trending or... -
Page 13: Establishing A Data Collection Route
10.0 ESTABLISHING A DATA COLLECTION ROUTE The Machinery Data Worksheet helps organize data for routine data collection. Vibration readings are taken on the Points (bearings) established in your route and recorded using your naming convention on the worksheet. Vibration, speed, temperature, pressure or any process data may be recorded using this type of systematic approach. -
Page 14: What Are You Measuring
We therefore analyze the “type” of vibration to identify its cause and take appropriate repair action. With overall vibration monitoring (VIB ISO) using the EXAMINER 1000, analysis of the cause of excess vibration relates to the monitoring equipment’s probe position; either horizontal, vertical, or axial. -
Page 15: Measurement Techniques
both measurement types for bearings and gearboxes. As ENV values begin to decrease, rely on VEL readings. Overall Vibration Monitoring — monitors normal, low frequency machine vibration. Detects rotational and structural problems like imbalance, misalignment, and mechanical looseness. Enveloping — amplifies high‑frequency, repetitive bearing and gear mesh vibration signals for early detection of bearing problems, but does not detect non‑repetitive rotational or structural events like imbalance, misalignment, and looseness. -
Page 16: Optimum Measurement Conditions
14.0 OPTIMUM MEASUREMENT CONDITIONS Perform measurements with the machine operating under normal conditions. For example, when the rotor, housing, and main bearings have reached their normal steady operating temperatures and with the machine running under its normal rated condition (for example, at rated voltage, flow, pressure and load). -

15.1 ISO 10816 Standard Comparison The ISO 10816 Standards provide guidance for evaluating vibration severity in machines operating in the 10 to 200 Hz (600 to 12,000 RPM) frequency range. Examples of these types of machines are small, direct‑coupled, electric motors and pumps, production motors, medium motors, generators, steam and gas turbines, turbo‑compressors, turbo-pumps and fans. -
