Triaxial Vibration Meter

Product catalog summary

Application
The VM30-W is a triaxial vibration meter designed for evaluating mechanical vibrations in onshore wind energy plants up to 3 MW, compliant with VDI 3834-1. It measures vibrations at various components such as the tower, nacelle, rotor bearing, gear, and generator using a single device and sensor.

Properties
The device features three independent measuring channels, selectable band filters, and displays interval RMS with up to 10 hours averaging time or running RMS. It measures vibrations from 0.1 Hz and displays both vibration acceleration and velocity. The device has a wide dynamic range with four gain ranges, a memory for data storage with a PC interface, and includes an Excel macro for data transfer and analysis. It is easy to operate, supports 10 user-defined setups, and operates for 20 hours on three AA batteries. The device is compact, has an IP65 protection grade, and comes as a kit with a high-sensitivity triaxial accelerometer KS823B and mounting accessories.

Technical Data
The measuring ranges for interval RMS of vibration acceleration are 0.010 m/s² to 40 m/s² across various frequency bands. The accuracy is ±3% and ±2 digits. Filters are available for different frequency ranges, and the display modes include interval RMS and running RMS. The device has three IEPE compatible input channels and supports calibration via a vibration calibrator or transducer sensitivity entry. It offers manual or autoranging gain settings and has an overload indicator for each channel. The memory can store over 1000 measurements with date, time, and comments, and recording modes can be manual or time-based. The PC interface is RS-232 with a USB adapter, and the display is a graphic LCD with backlighting. The signal output provides three buffered AC sensor signals. The device operates on three AA batteries or an external power supply and is protected against jet water with an IP65 rating. Dimensions are 165 x 92 x 31 mm, and it weighs 350 g.

Kit Contents
The VM30-W kit includes a triaxial accelerometer KS823B, sensor cable, magnetic base, wall adapter, signal cable, interface cable with USB adapter, and a mains plug adapter.
