Around X Axis
In this video you can see repeatability and sensitivity of this rotational sensor.
Video description:
Repeatability of this rotational sensor can be seen on the optical power meter (right) so, that at the still or steady state (constant angular velocity) of rotation the values on the power meter shall be the same. As the steady state of rotation is hard to achieve by hand we will point out repeatability at still state values.
At the still state, at the beginning of the video the display on power meter reads -14.16 dBm.
After some erratic movement when the sensor stops to rotate tilted to the left, the value on power meter display shows the value of about -14.2dBm.
After some erratic movement to the right the display of power meter shows the value of -14.3dBm after the sensor stopped moving.
Sensitivity during erratic rotational movement between the three still states described above the power meter shows any values between the highest of about -9dBm to the lowest of about -26dBm.
Comments:
- Sensitivity of this rotational sensor is adjusted for “medium” changes in the speed of rotation, e.g. for monitoring of axial rotation of high speed trains or large planes.
- Sensitivity from working point (stills state or constant state of angular rotation) at about -14.2dBm towards higher values (zero) decreases, whereas sensitivity towards lower values increases. This asymmetry is physical property of this type of measurement which can be made symmetrical by the use of mathematical formula or by the use of two sensors.
- Speed of used display (electronics) is too slow, so that the values on the display do not correspond exactly with the rotating changes of the sensor.
Usability of this rotational sensor is widespread as its sensitivity and ruggedness are highly customizable.
Applications of this rotational sensor can be seen in the following:
- construction industry (bridges, tunnels, buildings, …
- geological/earthquake monitoring
- large mechanical equipment (turbines, machine tools, ….)
- transport industry (ships, high-speed trains, planes, cars, ….)
via the usage of “additional” software for rotation recording and processing, it can be used for autonomous navigation system in transport industry (ships, submarines, planes …)
Further advantages of this sensor are:
- low energy consumption
-
highly customized sensitivity
-
different level of ruggedness
- electromagnetic compatibility (EMC)
Around Z Axis
In this video you can see repeatability and sensitivity of this rotational sensor.
Video description:
Repeatability of this sensor can be seen on the optical power meter (right) by the comparison of the values at the beginning of the video when the value on the display is -23.05 dBm and at the end of the video where the value on the display stands again at -23.05 dBm.
Sensitivity can be seen from the values on the display (on the right) just after one revolution before it comes to a stop ...
- when the sensor decelerates to the left after one revolution around Z axis the value on the display approaches -21dBm (a slow level of deceleration achieved by hand)
- when it decelerates to the right (still slower deceleration achieved by hand) the value on the power meter reads about -23.4dBm
- and then it settles at the value -23.05 dBm when it finally comes to a stop.
Comments:
- Sensitivity of this rotational sensor is adjusted for “medium” changes in the speed of rotation, e.g. for monitoring of rotation of large planes. It is possible to set different sensitivity levels from monitoring of slow rotation of large ships to high speed rotation of racing cars.
- Sensitivity from working point (-23.05 dBm) towards higher values (zero) decreases, whereas sensitivity towards lower values increases. This asymmetry is physical property of this type of measurement which can be made symmetrical by the use of mathematical formula or by the use of two sensors.
