The CEL-350 dBadge Series comprises
of the CEL-350 dBadge, the CEL-350L
dBadge 'Lite' and CEL-352 dBadge 'Plus'.
The CEL-350 dBadge Series is ideal for
personal noise exposure measurements
around the workplace. By using the
latest digital technology, the CEL-350
dBadge Series achieves new standards of
performance levels in noise dosimetry.
The dBadge design eliminates cables,
unlike traditional dosimeters, and weighs
only 71g. No other external equipment is
needed to operate the CEL-350 dBadge
Series. It is simply operated by the 2 keys
on the side of the instrument.
Battery life and memory capacity are
sufficient to perform many consecutive
shift measurements without charging or
downloading. Recharging the integral
NiMH battery can be achieved in 90
minutes. A variety of mounting options
are available for all types of working
conditions, making the CEL-350 dBadge
Series very easy to fit to the shoulder of
the employee and comfortable to wear.
The CEL-350L 'Lite' measures and stores
all necessary workplace noise parameters
simultaneously. The CEL-350 dBadge
model has additional functionality to
measure the time history of noise levels
on top of these cumulative levels, which
can later be graphed on the PC Software.
The CEL-352 dBadge 'Plus' model is also
available which measures simultaneous
'C' and 'A' weighted Leq measurements
as additional functionality. These can then
be used to calculate the effectiveness
of hearing protection by either the SNR
or HML method further increasing the
applications for this innovative product.
For any model no set-up is required so
there is no risk of measuring the wrong
parameters.
Key Features:
 Compact, rugged (rubber overmoulded) design weighs only 71g
No cables to damage or get in the way
Measures and logs all workplace noise parameters
28 hour battery life, fully charges in 90 minutes
Integrated display and visual exposure alarm
Simple auto-calibration function
Comprehensive software package
Intrinsically safe models available for use in hazardous atmospheres
Simultaneous 'C' and 'A' weighted measurements on the dBadge 'Plus'
Applications:
Measuring personal noise exposure
Assessing and monitoring noise in the workplace
Ensuring compliance with Workplace Noise Regulations
Selection of effective hearing protection (dBadge 'Plus')
Built in Display
Display shows measurement status and data
Unique LED action level alarm function
'Fuel gauge' display for memory and battery information
1 minute values of average and peak noise levels stored
The CEL-350 dBadge Series 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 Insight 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 Insight software.
Simple 2 key operation
Unique automatic calibration function
Lockable keys and display
Easy to mount on employees' shoulder
The CEL-350 dBadge Series is quick and easy to operate. After
switching the dBadge on, place the calibrator over the microphone
and the CEL-350 dBadge Series 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.

Casella Insight Data Management 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 Casella
Insight 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. Graphs can be analysed by adding zones (shown right)
which subsequently provides exposure levels inside and
outside these zones. This allows the exclusion of extraneous
events, breaks etc to provide comparative exposure
calculations. Any exclusion zones added to data are retained
with the data file.
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.
For larger organisations, data can be shared with colleagues
anywhere in the world with the inbuilt import and export
feature.
A 'backup database' feature is also included allowing data
to be stored on a secure drive within you company,
therefore preventing the loss of valuable data.
Report templates provided with the software can be
customised and saved, so that user-defined reports can be
easily generated. Reports can summarise the required dose
data and any information about the employees' working
day, together with the logged time history of noise exposure
throughout the day. This useful feature ensures exposure
data is presented concisely without having copy data to any
other software package to produce reports.
Casella Insight Data Management Software has many other
features, such as the ability to be used with other Casella CEL
instruments, for further details please see Casella Insight data
sheet.
Variety of Mounting Options
Safe and secure
Comfortable for the wearer
Can be fitted to all clothing types
The choice of mounting clips, ensures that through it's combined light
weight and size, the dBadge is both unobtrusive and comfortable to wear on
the shoulder. The dBadge is supplied with both the crocodile clips (fitted)
and the pin clip; alternative harness clips or hard hat mounts are
also available.
Mounting Options:
CEL-6351 Pin Kit
CEL-6352 Crocodile Clip Kit
CEL-6353 Harness Kit
CEL-6354 Hard Hat Kit
Intelligent Fast Charging System
Full charge gives the dBadge a 28 hour operating time
Fully charges in 90 minutes
Charger units can be linked together
Single mains supply can supply up to 12 dBadge units
Visual display of charge progress with unique 'fuel gauge'
Due to the battery technology and intelligent charging method used, the
dBadge unit does not have to be continually on charge. The standard
3-way charger can be used to manage many dBadge units.
When placed on the charger, the dBadge will display a 'fuel gauge' which
shows how much operating capacity, in hours, is currently held in the
batteries. When fully charged, the blue LED on the front of the dBadge
illuminates.
The dBadge does not have to be fully charged prior to use. A 30 minute
charge will give an operating time of greater than 8 hours, enough for a
typical working day.
A single CEL-6362 3-way charger is required. The number of charging
points can be increased using the CEL-6363 3-way charger extension kit.
Up to 12 dBadge units can be charged in this way.
Measurements Kits
Standard kits of 1, 2, 3, 5 and 10 units
Additional dBadges can be added to make any
quantity of kit
Robust kit case holds up to 10 dBadges and
accessories
dBadge measurement kits are available with various quantities of
dBadges and include all items necessary for workplace noise dosimetry
measurements. Each kit is complete with the appropriate number of
dBadge units, as well as a CEL-110/2 Acoustic Calibrator, infra-red
