Applications Using the Stroboscope to Measure RPM The primary use for a stroboscope is to stop motion for diagnostic inspection purposes. However, the stroboscope can also be used to measure speed (in RPM / RPS). To do this, several factors must be considered.
Page 38
Applications Using the Stroboscope to Measure RPM For example, when viewing a shaft with a single key way you will see one stationary image of the key way at the actual speed and at 1/2, 1/3, 1/4, etc., of the actual speed.
Applications Balancing and Phase Measurement If a Remote Optical Sensor or Magnetic Sensor is used to sense one pulse per revolution (External mode), the readout displays directly in RPM (FPM) without any adjustment required. In instances when you can shut down the device and install a piece of reflective tape, then an optical tachometer is easier to use for RPM measurement.

Page 41
Applications Balancing and Phase Measurement Headphone (CMAC 5078) and Strobe Adapter kit (CMAC 5402). Reference the Audio Headphone and Strobe Adapter User Manual for connection details. For CMVA Series Micrologs, you will need to use the included phase adapter (CMSS6135E) and strobe light cable (CMSS50278-CE).
Page 42
Applications Balancing and Phase Measurement proceed to the next point, and then repeat the process. The trigger must stay depressed until the Microlog is finished processing the data. If the Microlog does not respond to the phase reference signal supplied to it by the strobe, it is possible that the Trigger Setup in the vibration data collector may be reversed.
Applications Phase Analysis Phase Analysis The Strobe Light can be used to measure movement of parts of a machine, couplings and machine cases in a machine train. The direction of movement (Phase) reveals important information about looseness, unbalance and alignment. This section is not intended to be a comprehensive review of these measurements.
Page 44
Applications Phase Analysis • Start all measurements with the vibration transducer mounted on a bearing housing in the vertical direction. (This is a good habit to get into). Aim the strobe light at the selected reference mark and turn it on. •...
Applications Motion Studies • Move the vibration transducer to each end of the machines in a train. Position the vibration transducer axially at these • locations for these measurements. • Keep track of the phase for each measurement location. As the vibration transducer is moved to each location, its direction keeps changing from North to South, for example.
Page 46
Applications Motion Studies example, use 6-foot intervals. Draw a simple diagram on paper. Start at the machine end, adjust the strobe light • to running speed, and note the phase reading using the clock face method. (For reference, adjust the phase marker to 12 o’clock.) Move the vibration transducer to each location, noting the phase reading at each.
Limitations of Remote Optical Sensors Remote Optical Sensors (ROS) have a slight limitation when used with the Strobe Light because they sense not only the reflective marker but the strobe flash as well. If the ROS is positioned near the strobe, the light from the strobe may cause the ROS to trigger the stroboscope at the wrong time, especially when using a delayed flash mode.
Lamp and Fuse Replacement Lamp Replacement WARNING: Before attempting to remove the lamp, make sure the stroboscope is turned off and any mains cords are removed from the AC outlet. Allow at least five minutes for the lamp to cool. The stroboscope is designed to discharge the internal high voltages within 30 seconds.
Lamp and Fuse Replacement Lamp Replacement WARNING: Do not touch the new lamp with bare fingers. • The lamps are polarized and must be put into the socket matching polarity. Using a lint free cloth, match up the red dot on the plug with the red dot on the socket and gently rock the lamp while pushing it into place (see Figure 4).
Page 51
Lamp and Fuse Replacement Fuse Fuse Under normal operating conditions, the fuse within the stroboscope should never blow. Examples of abnormal operating conditions would be foreign materials entering the strobe, such as water, pulp, ink, etc. The Strobe Light has a resettable fuse, which will reset once conditions are normal again.
Battery and Power Supply Specifics The Strobe Light is fitted with rechargeable NiMH (Nickel Metal Hydride) batteries. These batteries contain fewer toxic metals than NiCd (Nickel Cadmium) and are currently classified “environmentally friendly”. They also have 30% more capacity than NiCd batteries of the same size. Like NiCds, NiMH batteries are prone to self- discharge - 10 to 15% of charge is lost in the first 24 hours then continues at a rate of 0.5 to 1% per day.
Battery and Power Supply Specifics Charging the Batteries Low Battery Icon - Outline blinking (very little time left) The strobe has a protection feature that prevents the strobe from operating if the battery voltage is too low. This condition is indicated by no flash and the display shows LO BAT.
Battery and Power Supply Specifics External Power Supply / Charger performance. If the batteries are not charged to 100% regularly, the batteries will lose capacity. External Power Supply / Charger The external power supply / charger can also be used to run the stroboscope continuously from the AC mains (115 / 230 Vac).
