Hand arms Vibration Meters
Hand-arm Vibration Meters
Description
Our measurement system enables vibration monitoring on handheld tools using autonomous, wireless sensors. Data is downloaded from the sensor at the end of the workday via a docking station connected to a PC.
The software automatically calculates workers’ hand-arm vibration exposure, comparing it to the limits set by the vibration Directive.
To accommodate various tools, two sensors are available: one for standard vibrating tools and another for high-impact tools generating up to 50,000 m/s² of shock.
Our device, attachable to any tool, provides precise measurements without disrupting tasks, and a special version is designed for high-impact tools.
Features
- Self-contained miniature sensor without wired connections
- Accurate measurement on all types of handheld tools, including highly percussive tools (up to 5000 G)
- Automatic computation of standardized exposure values
- Fully compliant with the European Vibration Directive
- User-friendly implementation and use
- Includes means of avoiding common measurement errors
- Non-intrusive
- Reasonable cost
Models
Standard Sensor:
- Measurement range: ± 2000 m/s²
- Maximum measurement noise: 0.010 m/s²
Highly Percussive Tools Sensor:
- Measurement range: ± 50000 m/s² (1)
- Maximum measurement noise: 0.50 m/s²
(1) Sensor range (including internal mechanical filters)
Software
- Windows™ software
- Access to measurements from one sensor or more using the supplied docking station
- Automatic computation and display of workers’ exposure to hand-arm vibration, and comparison with the limit and action values defined in the European vibration Directive
- Storage and export of vibration time history for further processing with analysis software (option)
Compliance
- Fully compliant with the European Vibration Directive 2002/44/EC and related standards ISO 5349-1 and 5349-2
- Compliant with the ISO 8041: 2005 standard (Human response to vibration – Measuring instrumentation)
- Weighting filters according to ISO 5349-1
- The sensors are supplied with coupling devices for firm and stiff attachment to the tools as per ISO 5349-2
-
Developed in partnership with INRS (Research Center for Safety, France)
The sensing device is composed of a miniature case to be fixed to the tool and includes:
- A 3-axis accelerometer
- An electronic circuit acquiring, processing (weighting filters) and storing the acceleration values
- A compact battery
- A communication circuit to access stored values (not used during measurement)
- An indication of operation (LED)
The available range includes two sensors that look the same and operate identically, but exhibit different characteristics:
- The first one allows for measurements to be taken on most common handheld tools
- The second one is specifically designed for highly percussive tools (e.g. rammers, rock-drills etc.)
The sensors are plugged into the docking station, which is connected to the PC.
These are then made ready to measure.
As soon as they are unplugged from the docking station, they can be attached to the tool(s) within a given period of time (user parameters).
At the end of the measurement period, the sensors are plugged back into the docking station.
Measurements are downloaded from each sensor and the worker’s exposure to hand-arm vibration is computed, eventually taking into account the different tools he has been using.
uIn order to avoid measurement error phenomena, special provisions have been implemented (i.e. integrated 3-axis mechanical filter).
These provisions allow any user – whether an expert in vibration or not – to obtain accurate and consistent measurement results.
In its basic version, Vib@Work Hand-Arm comes in a carrying case with a capacity of 4 sensors including:
- A vibration sensor (standard sensor or sensor for highly percussive tools)
- Sensor attachment means
- A docking station (4 sensor capacity) for charging and communication between the sensors and the software
- A communication cable between the docking station and PC (USB port)
- A charger
- A user manual
- The dose computation software on CD
