Vibrations dosimeter

Vibrations dosimeter

Product catalog summary
Overview: The whole-body vibration dosimeter is designed for user-friendly operation, even by non-experts. It automatically computes exposure levels as per the European directive 2002/44/CE and measures exposure time. Results can be accessed directly via a laptop or PocketPC, with a short learning curve and reasonable cost.
Storage Capacity & Autonomy: The sensor can store up to 36 hours of measurement data and operates for over 20 hours with Bluetooth® disabled. It supports a minimum of 500 battery charge cycles.
Measurement Accuracy: The display resolution for RMS weighted accelerations is 0.01m/s², with a maximum error of 0.05m/s² over an 8-hour period. Frequency weightings conform to ISO2631 standards.
Compliance and Testing: Developed with INRS, the device complies with ISO2631 for vibration exposure measurements. Acceptance testing follows EN ISO 8041:2005 standards.
Charger Specifications: Input: 100~240VAC 50~60Hz 150mA; Output: 5VDC 1000mA.
Wireless Communication: Bluetooth® Class 2 with a range of up to 30 meters in open fields, operating in the ISM Band 2.4 GHz.
Electromagnetic Compatibility: Tested for radiated emissions (EN 55022) and immunity (EN 61000-4-8/6/2/3).
Physical Characteristics: The sensor has a diameter of 205 mm, height of 12 mm, and weighs 350 grams, complying with ISO10326-1.
Environmental Conditions: Operating range is from -10°C to 50°C, with charging conditions from 0°C to 40°C.
Sensor Dynamics: The device features specific parameters for chocks resistance, accelerometer resonant frequency, mechanical and electrical crosstalk, and time measurement accuracy, ensuring precise and reliable measurements.
