Intrinsically safe noise dosimeter SV 104BIS

The intrinsically safe dosimeter is a noise dosimeter designed by the ATEX directive and the IECEx performance specifications. The intrinsically safe dosimeter is typically used in occupational noise measurements in areas such as mines and petrochemical plants where it is necessary to secure intrinsic safety.

The dosimeter is covered by a 3-year warranty and a life-time warranty for the patented MEMS microphone. The intrinsically safe dosimeter uses a new type of docking station for fast data transfer and quick battery recharging.

SV104BIS - the newest version of intrinsically safe dosimeter for 2022

The SV 104BIS is the newest version (2022) of an intrinsically safe noise dosimeter. Like its predecessor, the SV 104BIS is a cable-free dosimeter and is typically attached to the user’s shoulder, close to the ear using the mounting clips supplied.

Among the unique features of the new model, the software is automatic noise dose calculation, sound pressure level logging, audio recording, octave band frequency analysis, and auto-calibration. The new ATEX dosimeter has an 8GB memory and fast data transfer via new docking stations. The new Bluetooth® interface enables previewing current results on a mobile app.

ATEX Noise Dosimeter

Intrinsically safe noise dosimeter

ATEX and IECEx certification

Intrinsic safety (IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. The SV 104BIS is the IS personal noise dosimeter in accordance to ATEX directive and IECEx certification scheme.

New hardware

patented MEMS microphone and faster data transfer

The new SV 104 BIS is equipped with the new MEMS microphone, which offers a measuring range from 53 dB Leq to 143 dB Peak. The list of addons includes new large 8 GB memory and fast data transmission with a new completely docking stations.

New firmware

Options for noise sources recognition

The large 8 GB memory enables the SV 104BIS to record 1/1 or 1/3 octave bands in real-time and simultaneous audio recording. The 1/1 octave analysis is often used for the selection of hearing protectors. The 1/3 octave function allows the determination of the influence of high or low frequencies on overall values. Audio recording is synchronized with a noise time-history and it can be opened and played back in PC software enabling noise source recognition.

Mobile application

Remote connection via Bluetooth® interface

The Bluetooth interface enables current results to be previewed on a smartphone Assistant application without disturbing the workers. The smartphone application signals alarms when the set noise limits are exceeded.

Measurement accuracy

in accordance with ANSI S1.25 and IEC 61252 standards

The dosimeter has been designed to meet requirements of the ANSI S1.25 and IEC 61252 standards for noise dosimeters and the IEC 61672 standard for class 2 sound level meters. SV 104BIS r is suitable for noise exposure measurements in accordance to the ISO 9612 as well as OSHA, MSHA and ACGIH standards. The time history logging of results such as Leq, Max, Min and Peak with two simultaneous logging steps is saved in internal memory. All dosimetry results such as DOSE, TWA, Lav are also included.

Auto-calibration

automatic start of calibration

We have designed the SV 104BIS to make noise dosimetry measurements easier, once the SV 104BIS detects a calibration signal, it calibrates automatically saving the calibration data together with the measurement fi le, before and after measurement.
