RIDEwatcher Now with 3D-Abilities

Optional horizontal acceleration sensors may be added from now on to RIDEwatcher. This enables RIDEwatcher to detect acceleration in all directions. If the measuring results are transferred to the corresponding PC software, the curves of the X- and Y-axes will be available and can be evaluated.
rw_3achs.jpgRIDEwatcher is a so called "Multimeter for Ride Profiles" of lift systems. It helps setting up elevators and automatically evaluates the measuring results.
It is possible to use the device without time-consuming training or familiarization; you will quickly be able to obtain information for the correct set-up of lifts or for the elimination of defects.
imgrw1.jpgThe standard RIDEwatcher has an acceleration sensor in the vertical direction for recording and analyzing drive profiles. The results are displayed directly on the device’s screen and can be analyzed directly on site. With the help of the free PC software, curves can be examined more closely and reports may be generated for documentation.
imgrw2.jpgBased on the stored limits the measuring results are, depending on the type of lift, evaluated and a corresponding assessment is issued.
With the now available optional "X- and Y-axes for RIDEwatcher existing units may be extended by two horizontal axes, thereby enabling RIDEwatcher to record the horizontal accelerations and vibrations after the upgrade.
If the measurements are transmitted to the associated PC software, curves in the X- and Y-directions will be available and can be evaluated.

imgrw3.jpgA new function enables the PC software to perform a vibration analysis of all three directions of acceleration. The constant drive section (driving time and rated speed) is examined for its vibration behavior and, separated by the acceleration directions, the following characteristics are being determined:
• Vibration Max. Peak to Peak
• Vibration A95
• Vibration Max. Zero to Peak
The A95 value is of special importance. This value is to be regarded as kind of an average of the vibrations during constant travel: 95% of all peaks within the constant travel are smaller than the output value. By eliminating individual deviations the A95 value describes the average vibration behavior of the elevator system quite well. The distance (the mathematical difference) between the A95 value and the Max. Peak to Peak value is also interesting. If the distance is relatively small, the lift drives fairly homogenous; guide rail joints seem to be well executed, emergency brake marks have been well leveled out, etc.. A fairly large distance between the two values on the other hand indicates problems with the smooth running of the elevator. Especially rail joints, emergency brake marks, threshold passages and the guides should be examined more closely remedy any faults.
With the 3-axis option for RIDEwatchers the capabilities of the device are potentiated. New dimensions are opened for the user not only by the acceleration measurement, but also through the evaluation possibilities.
