Noise Dosimeter

OVERVIEW

The CEL-350 dBadge is ideal for personal noise exposure measurements around the workplace.The dBadge design eliminates cables and weighs only 68g. No other external equipment is needed to operate the CEL-350 dBadge. It is simply operated by the 2 keys on the side of the instrument. All necessary workplace noise parameters are measured and stored simultaneously, for later download to a PC, no set-ups are required and no risk of measuring the wrong parameters. Battery life and memory capacity are sufficient to perform many consecutive shift measurements without charging or downloading. The CEL-350 dBadge very easy to fit to the shoulder of the employee and comfortable to wear.

The CEL-350 is the first compact noise badge product to be designed with a display. This internal display makes it easy to perform calibration, provides status information and shows key measured data. The dBadge has a unique ‘fuel gauge’ to display memory and battery status, ensuring the exact remaining battery and memory capacity can be viewed on the display. Also a unique feature of the dBadge is the alarm function. An ultra-bright LED on the dBadge gives a visual indication of when exposure action levels have been exceeded by flashing at different rates. These action levels can be configured via the dB35 software and used to instantly see if noise control or hearing protection measures are needed. The alarm function can be switched on or off via the dBadge keys.
In addition to noise exposure parameters, the time history of the noise is logged in 1 minute values of both the average noise level and the peak value for subsequent analysis of how the noise exposure has occurred. This data can be viewed and analysed via dB35 software.

The CEL-350 dBadge is quick and easy to operate. After switching the dBadge on, place the calibrator over the microphone and the CEL-350 dBadge will auto-calibrate, and store the calibration data and time, ensuring accurate and validated results. The unique design of the windshield ensures it can be securely clipped into place to give protection in dusty environments and prevent air movement affecting the measurement. The dBadge can be started and the keypad locked before being placed on the shoulder of the employee. Overall, a measurement can be started within seconds of
switching the dBadge on. At the end of the measurement run,  simply unclip the dBadge. The data can be viewed on the easy to read graphic display to ensure the noise measurement was valid.
Consecutive measurements can be taken without the need to charge or
download the dBadge.

SOFTWARE

	Store results in simple tree structured database, by person, place or process etc
	Automatically colour codes results for exceeded noise action levels
	Graphical display and analysis of noise time history
	Automatic report generation
	Data can easily be exported to other applications

The dBadge downloads to a PC automatically using dB35 software, simply by pointing the dBadge at the infra-red download cable provided. Once downloaded, data can be stored under an employees’ name, location or process so that a database of noise exposures can be built up. An automatic colour coding system can be used to highlight which employees have been exposed to specific noise action levels. The time history of the noise exposure is displayed graphically and can be analysed to see when the majority of an employees’ exposure has occurred. Report templates provided with the software can be customised and saved, so that user-defined reports can be easily generated. Data can be viewed according to different measurement protocols, either ISO (Europe) or OSHA (USA). Alternatively the data displayed can be customised to a specific users own requirements.
