Audio-R unit also provides a modulated sound according to the detected rate activity. These capabilities improve the user's experience by eliminating interference, thus simplifying a blind or otherwise difficult search.
The Audio-R device improves the audible detection abilities of the Radiagem meter, allowing the user to listen to the measurement achieved by the Radiagem unit or a connected probe using headphones with additional audible reporting capabilities.
The Audio-R device provides a differential measurement that makes searching for hot spots easier. The Audio-R unit is auto-adaptative and automatically subtracts the ambient radioactivity background Rate from the audible report. An Audio-R device also provides a modulated sound according to the detected rate activity. These capabilities improve the user's experience by eliminating interference, thus simplifying a blind or otherwise difficult search.
The Audio-R unit is especially useful in crowded or noisy areas such as plants or outdoor measurements, when Radiagem meter's sounds may be obscured by local activity. It can also be used to prevent others from hearing your measurement signals, well suited for areas where quiet operation is required (e.g., hospitals or for special Homeland Security requirements).
The Audio-R unit connects between the probe and the Radiagem meter's CSP input. It is compact and firmly attachs to the Radiagem unit. It is supplied with headphones which incorporate a volume control. Audio-R devices automatically deduct the background from the measurement. Once in a constant background, after a defined amount of time, the module will subtract the background from the measurement. Then only variations around the background will be recorded in the headphones.
The headphone sound reflects the radiation detected by the probe. For high sensitivity probes (e.g., SX-2R), th Audio-R unit prevents headphone saturation. The pulse frequency increases proportionally to the Dose Rate measured. Over a defined level, when the pulsed signal increases, the pulse frequency progressively becomes a pure tone. This tone then increases relative to the activity, up to 3 kHz. When the alarm level is reached, this tone becomes a two-tone alarm.
