The doseBadge noise dosimeter mounts on a worker's shoulder to measure and store the noise exposure throughout the working day or shift. The doseBadge contains a rechargeable battery, microphone and acoustic processor, all inside a strong metal case that clips on to the worker's clothing or overalls. It is well positioned to measure the noise levels close to the ear.
The doseBadges are controlled using a Reader (included in the CK110AIS/x kits). The Reader communicates with the doseBadge over an infra-red link, like a TV remote control. This means you can mount the doseBadge on the worker and, once you have finished fitting it, start the actual measurement.
The Reader also includes a sound level calibrator to check the function of each doseBadge before use. This is a requirement of most occupational noise regulations.
The CR110AIS and CR112AIS versions of the doseBadge are approved for use in hazardous and potentially explosive atmospheres, making them ideal for the petrochemical industry and underground mining.
The I.S. version of the doseBadge makes all the same measurements as the standard doseBadge Industrial. It is coloured gold to clearly differentiate it from the standard non-approved version.
The doseBadge intrinsically safe noise dosimeter is the part that mounts on the worker's shoulder. It is a small, lightweight device that should not interfere with the worker's duties.
The doseBadge is the only part of the system that is I.S. approved as this is the only part that needs to be present in the hazardous environment.
Weighing just 51g (1.8oz), the doseBadge has no cables or controls, making it safer around machinery and limiting the effects of tampering.
The dosimeter should be fitted to the worker at the start of the day or working shift and left to measure the total noise exposure.
The main noise measurements taken by the doseBadge depend on the settings and the regulations being followed.
To satisfy different regulations around the world, the doseBadge can use an exchange rate of 3dB, 4dB or 5dB. It has dual channels, with channel 1 configurable and channel 2 set to make ISO 3dB measurements.
The doseBadge can be set to indicate when the noise dose has exceeded 100% (e.g. 85 dBA for 8 hours). Under normal conditions, the blue LED flashes once every second. When the noise exposure limit is exceeded, it flashes twice every second.
These approvals apply to the CR110AIS and CR112AIS versions of the doseBadge noise dosimeter, which are included in the CK110AIS/x and CK112AIS/x noise dose kits.
The Intrinsically Safe versions of the doseBadge have been independently tested and verified by a number of different test laboratories to ensure that it meets the requirements of the different Intrinsic Safety standards.
These tests ensure that under defined test conditions the doseBadge will not cause a spark or will not heat up and cause a flammable atmosphere to ignite. Within these standards there are many different levels of performance and it is essential that you have the correct level of performance for the environment in which your equipment will be used.
Only the doseBadge itself (the shoulder mounted part) and its mounting are approved for use in potentially explosive atmospheres. None of the additional items, such as the Reader and Charger are approved. All tasks such as charging, calibrating and initializing the doseBadge should be done outside the hazardous area.
The CR110AIS has ATEX, EEx, IECEx and FM approval for use in Group I non-mining and Group II mining applications.
Group I Non-Mining Applications:
Group II Mining Applications
The CR112AIS version of the Intrinsically Safe doseBadge has MSHA approval for use in mining applications.
Leave the doseBadge measuring for the full working shift...
The measurements can be viewed on the Reader's built in graphic screen or they can be transferred to a computer for storage, analysis and reporting. The Reader can download a number of doseBadges before the measurements are transferred to a computer, so it is only necessary to carry the Reader on site.
The doseBadge kits include the NoiseTools software, which is used to download the measurements from the Reader and produce noise reports.
The NoiseTools software runs on a Windows PC, supporting versions 7, 8 and 10. There are no licence restrictions so it can be installed on as many computers as needed.
Although doseBadges and Readers can be bought individually, they are usually included in a complete noise measurement kit that includes everything you need to make occupational noise measurements.
The CK110AIS/x kits include:
|doseBadges||Standard kits include 1, 2, 3, 5 or 10 doseBadge dosimeters, but other quantities can be supplied|
|Reader||One Reader unit is used with multiple doseBadges|
|Calibrator||Built in to the Reader unit|
|doseBadge Mounts||One mount for each doseBadge|
|Charger||For charging the doseBadge batteries|
|Software||The NoiseTools software|
|Certificates||Calibration certificates for each doseBadge and Reader (calibrator)|
|Carrying Case||Holds all doseBadges, Reader, charger and manuals|
Windshield The doseBadge windshield not only reduces the noise from strong wind but also provides additional protection against light rainfall, dust and the noise generated by knocks against the microphone.
Helmet Mount These allow the doseBadge to be fitted on the side of a helmet that is fitted with earmuff mounts. Note that the helmet mount is not approved for use in hazardous environments.
Keyfob Remote Control The Keyfob can be used instead of the Reader to Start and Stop the doseBadge. You still need a Reader to calibrate and reset the doseBadge but the Keyfob is much more handy for use in the field.
