Detecting vibration and displacements on structures, machine parts and building quick and effortless becomes now possible.
The RSV-150 Remote Sensing Vibrometer is designed for condition monitoring and testing of dynamics of structures from a
remote distance with a simple point-and-shoot operation. Its advanced laser Doppler interferometer technology saves time by
avoiding contact sensor installations and it’s ready-to-use for trouble shooting for any vibrational issue.
(Laser) light is the sensor.
With the RSV-150 Polytec provides a full solution for the vibrational analysis:
An interferometric optical sensor equipped with long range lens and
an in-line video camera for targeting. A green targeting laser allows precices
targeting on short and medium distances. The image of the video camera shows
precisely the measurement spot on any distance. The RSV-150 is shipped
with a rigid tripod system featuring coarse adjustment with a 3-way geard head
and additional fine adjustment for precise targeting on remote objects.
RSV-150 Remote Sensing Vibrometer
A controller to convert the sensor signals in voltage outputs for velocity and displacement.
The RSV-150 output is a non-proprietary and thus is can be used with any data aquistion system or data logger.
high range > 100m depending on the surface reflectivity and the amplitude - allows for remote access to hazardous area, e.g. explosion hazard or electric hazard for high-voltage electrical power supply components
µm resolution - reveals also slightest displacements
True 0 Hz capabilities with mHz resolution - low frequency response and displacement measurements on civil structures
Wide bandwidth up to 25 kHz - enables condition monitoring e.g. of gearboxes
Class 2 laser - safe operation without laser safety restrictions
in-line video camera - full visual control and easy targeting
Easy setup in minutes and point-and-shoot operation – no cabling or measurement point preparation
Works for nearly all surface properties – effortless measurements on encrusted and dirty location without prior cleaning
e.g. in mining environments
Independent from measurement point temperature – remote measurements also on hot surfaces like furnaces, pipes etc.
A-VIS-SCOP1 Scope with variable magnification 3-9 x 40. Parallax adjustment for different distances.
Fits to the accessory rail of the RSV-I-150 Sensor.
Delivers a wider field of view compared to the inline
camera for a better overview on uniform targets like
cable of stay-cable bridges.

When monitoring the dynamic behavior of
civil structures like bridges, the RSV-150
Remote Sensing Vibrometer is an ideal tool
for a cost effective measurement of
resonance frequencies, displacements and
for non-destructive vibration testing.
Due to it's long-range sensing capabilities
even minute pier displacements under
defined loads can be resolved from a
In condition monitoring the accessibility
of measurement points is an issue
which can make predictive maintenance costly. Especially for monitoring and
troubleshooting the RSV-150 Remote
Sensing Vibrometer is the versatile
alternative to contact sensors. It senses vibrations also on remote points with the same precision as with contact
It's unique features enable precise localization of vibration problems from a distance.
Hazardous areas can be avoided due to the high stand-off distance.
