Polytec's RSV-150 offers a full solution for vibration analysis: An interferometric optical sensor equipped with long range lens, an in-line video camera and additional green pilot laser for targeting at short and medium distances. The video camera image shows the measurement spot location at any distance. The RSV-150 is shipped with a rigid tripod system featuring coarse adjustment with a 3-way geared head and additional fine adjustment for precise targeting on remote objects.

The controller converts the sensor signals into a voltage output for velocity and displacement. The RSV-150 output is non-proprietary and thus it can be used with any data acquisition system or data logger.  

The Remote Sensing Vibrometer RSV-150, designed to measure vibration and displacement from remote distances, expands its applications the controller RSV-E-150-M.

The new controller expands the max. velocity to 24 m/s, which is the level of the current High Speed Vibrometers HSV (30 m/s), but with much higher range and optical sensitivity. The bandwidth is expanded as well to 2 MHz (25kHz with the standard –B controller).

The main applications are found in ultrasonic NDT, e.g. on tracks or for leak detection, as well as in applications requiring high speeds and accelerations like in falling towers and pyroshock experiments.

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 cables of stay-cable bridges.

A-MON-TFT3  TFT monitor for display of sensor video signal. TFT-Monitor with mounting set. Connects to the video output of the controller to display the targeting area via the sensor head camera. Resolution: 640x480 pixel

When monitoring the structural health or dynamic behavior of structures like bridges and industrial plants, the RSV-150 Remote Sensing Vibrometer is an ideal tool for the cost-effective measurement of resonance frequencies, displacements and for non-destructive vibration testing.

Due to its long-range sensing capabilities even minute pier displacements under defined loads can be resolved from a distance.

In condition monitoring, the accessibility of measurement points is an issue, which can make predictive maintenance costly. The RSV-150 Remote Sensing Vibrometer is the versatile alternative to contact sensors, especially for monitoring and troubleshooting. It senses vibrations on remote points with the same precision as contact sensors.

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.
