SVANTEK 977A

Svantek

The SVAN 977A is a successor of SVAN 977 offering bigger memory 8 GB and the Bluetooth® interface as a software option that can be enabled at any time. The meter provides broad-band results such as Leq, Max, Min and Peak with all standard weighting filters together with an incredible time-history logging feature with two adjustable logging steps. 

SVANTEK

One unique feature of the SVAN 977A is ultrasound measurement band up to 40 kHz. The ultrasound band is normally considered as the frequency range above 20 kHz. Ultrasound is used in a number of industrial processes such as cleaning, drilling or welding as well as hospitals for medical procedures.

The built-in Bluetooth® interface together with smart-phone application, SvanMobile, extends measurement capabilities with all the features offered by smartphones including text/voice comments, photo, video, GPS position etc.

SANTEK

With the option of time signal recording SVAN 977A can record the raw signal samples with defined frequency up to 48 kHz. Analysis of the raw signal is used whenever frequency analysis is not sufficient. Post-processing of high quality wave files (48 kHz, 24 bit) such as calculation of tonality is available in SvanPC++ program. Time signal is recorded in a wave format which means that it can be played back in the PC software and used for noise source recognition (audio recording).

The SVAN 977A kit consists of SVAN   977A Class 1 sound & vibration level meter with a detachable preamplifier SV 12L and high quality omni-directional SV  7052E microphone, compliant to IEC61094-4. The list of accessories includes: SA 143 carrying case, SA  22 windscreen, 8 GB microSD card, four AA batteries, USB cable, and CD with user manual. Each SVAN     977A has its factory calibration certificate and 36 months warranty card.

With an optional microphone and 1/3 octave or FFT analysis SVAN    977A provides analysis of the ultrasounds up to 40 kHz. The ultrasound band is normally considered as the frequency range above 20 kHz. Limits of permissible ultrasound levels are usually expressed in terms of Leq and Max values specified in 1/3 octave bands for 20 kHz, 25 kHz, 31.5 kHz and 40 kHz.

内置的Bluetooth®接口与智能手机应用程序SvanMobile一起扩展了测量功能，具有智能手机提供的所有功能，包括文本/语音注释，照片，视频，GPS位置等。

---

通过时间信号记录选项，SVAN 977A可以记录定义频率高达48 kHz的原始信号样本。只要频率分析不充分，就会使用原始信号的分析。 SvanPC ++程序中提供了高质量波形文件（48 kHz，24位）的后处理，例如音调计算。时间信号以波形格式记录，这意味着它可以在PC软件中播放并用于噪声源识别（音频记录）。

SVAN 977A套件包括SVAN 977A 1级声音和振动水平仪，带有可拆卸前置放大器SV 12L和高质量全向SV 7052E麦克风，符合IEC61094-4标准。附件清单包括：SA 143便携包，SA 22挡风玻璃，8 GB microSD卡，四节AA电池，USB线和带用户手册的CD。每个SVAN 977A都有出厂校准证书和36个月保修卡。

----

通过可选的麦克风和1/3倍频程或FFT分析，SVAN 977A可提供高达40 kHz的超声波分析。超声波带通常被认为是20kHz以上的频率范围。允许的超声波水平的限制通常用在20 kHz，25 kHz，31.5 kHz和40 kHz的1/3倍频程频带中指定的Leq和Max值表示。
