Larson Davis Announces Next Generation Human Vibration Meter

December 30 2015, 03:10

Larson Davis, a division of PCB Piezotronics, announced the release of the new HVM200 Human Vibration Meter that implements the latest measurement technology for industrial hygiene and product testing applications. The HVM200 is a small rugged vibration meter with built in Wi-Fi that can be used to measure hand-arm, whole body and general vibration. It includes the metrics and frequency weightings needed to measure human vibration. This 3 channel meter meets the requirements of ISO 8041:2005 and it is designed to measure per ISO 2631-1, 2 & 5 and ISO 5349. This makes the HVM200 an ideal choice for an instrument used to demonstrate compliance with human vibration requirements and regulations worldwide.

The HVM200 is used to measure human exposure to vibration in order to prevent injury and better understand workplace hazards and product performance. The HVM200 includes the functionality needed to measure the hand-arm vibration and whole body vibration requirements in support of the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values (TLVs) and directive 2002/44/EC of European Parliament.

This meter provides options available for 1/1 and 1/3 octave filters (0.5 Hz to 2000 Hz and 0.4 Hz to 2500 Hz respectively) and raw vibration data recording. This allows users to determine the frequency content of measured vibration levels by configuring the HVM200 with the optional IEC 61260 class 1 compliant 1/1 and 1/3 octave filters (0.5 Hz to 2000 Hz and 0.4 Hz to 2500 Hz respectively). Because the HVM200 supports a large removable micro SD memory (up to 32 GB), it is now possible to store and archive the sampled time data for all three channels. Data is stored in a 24-bit format and files can be read with tools such as MATLAB or GNU Octave for additional processing. Data can also be archived or transferred using USB or Wi-Fi.
Industrial hygienists and product test engineers can leverage the power of their phones or tablets by acquiring the free app available on Google Play and the Apple App Store. This app can be used in conjunction with the HVM200 to setup a test, make the measurements, and view the results.
Vibration data taken with the HVM200 can also be viewed and analyzed on a personal computer using the HVM option for the Larson Davis G4 software. The G4 HVM software option allows downloading and data analysis in graphical or tabular format. This allows to perform “what-if” analyses by graphically modifying the data and recalculating results and generate reports or export data for archival or further processing.
“With this new product, measuring human vibration exposure is as easy as using an App on your phone or tablet. All the required functionality is built in and made simple from setup to results,” says Ken Cox, Larson Davis product manager.
