Integrating basic sound level meter
with 1/1 and 1/3 octave analyzer
according to IEC 61672 and IEC 61260
PTB model registration DE-20-M-PTB-0033
Overview
Tango Plus features
The Tango Plus sound level meter according to IEC 61672 with 1/1 and 1/3 octave analyser for workplace and environmental protection applications. Due to its intelligent software concept and its measuring range of 110 dB without switching to another range, TangoPlus is still very easy to operate despite its high functionality.
It is possible to use the detachable microphone & preamplifier
via extension cable. An outdoor protection kit is available
on request. The measured values are shown on a TFT
colour display and are readable even over larger distances
in sunlight or in darkness. The clearly arranged keyboard
has a perceptible keystroke.
Tango Plus has, based on state-of-the-art circuit technology,
a very low power consumption. Two batteries (1.2 ... 1.5 V,
size AA) guarantee an operation time of 40 h and a storage
time of 10 years (for lithium batteries). Therefore TangoPlus
is practically always ready for use.
The instrument has a real-time frequency analyser function
for 1/1 or 1/3 octave values.
The Tango Plus sound level meter allows for simultaneous A and C-frequency weightings as well as Fast, Slow and
Impulse time weightings. In addition to the momentary
sound level values, the instument allows the maximum and
minimum sound level values over a given period to be measured.
Tango can also measure the LAeq, LCeq, LAtm5 and
LAtm5-LAeq values.
The instrument has a real-time frequency analyser function
for 1/1 or 1/3 octave values.
All measurement values chosen in the Setup are computed simultaneously and one of these values is selected for display. After starting the integrating measurement, all values are saved automatically. With the help of the USB interface and the Tango Utilities software, the measured values can be read from the memory, saved and converted to a standard office format. Additionally, the software allows a user-defined setup to be defined and transferred to the device (measured values, storage cycles, percentiles).
Typical application of Tango Plus:
- Traffic and industrial noise measurements
- Neighborhood and recreation noise monitoring
- Workplace noise measurements
- Monitoring / logging of traffic noise
- Occupational noise measurements
- Frequency analysis in 1/1 or 1/3octaves in real-time.
Modern technology combines utmost accuracy with simplest operation
The accuracy of the measurement may be considerably improved by calibrating the sound level meter before each measurement. This calibration also remains intact after switching off the device. Because of its reasonable price, easy operation and small dimensions, TangoPlus is the ideal instrument for all users whose measurement tasks require a Class 1 measuring device according to the IEC 61672 standard.
A comprehensive memory management scheme allows different storage cycles to be selected for the various measurement values. In order to prevent incorrect settings from being selected by inexperienced users, the Setup function can be disabled via the interface (Easy Operator Mode).
Type approval by the PTB (legal calibratability in Germany) has been applied for.
Frequency analyser in 1/1 and 1/3 octaves
The Tango Plus sound level meter includes a real-time frequency analyser function with 1/1 and 1/3 octaves according to IEC 61260 class 1 as standard.
Workplace protection applications
For labor protection applications, in addition to the Cweighted values, the exceedance times for three freely-selectable LCPeak thresholds can be measured. This non-standard measurement values allows the degree of noise exposure at a workplace to be captured much better than a measurement of the peak value alone.
Environmental protection applications
Tango Plus allows three freely-selectable statistical values to be measured and saved. These LAFN% percentiles express what A-weighted level was exceeded in N% of the measurement time.
Highest ease of use via integrated software package TANGO-Utilities for Window
The TangoPlus sound level meter may also be operated via USB interface. In this case the PC powers the device through the interface (the scope of delivery also includes a USB adapter for mains power supply). The included Tango-Utilities software allows the operation and configuration of the instrument via PC as well as the data transfer between the two devices.
A separate window is displayed on the PC which allows easy setting of the parameters and rapid transfer of the stored measurement values. A unique feature of Tango is that several measurement values can be stored with individual sample times. The file names and sizes of the saved measurement values are displayed for transfer or deletion. The USB interface also enables the user to integrate TangoPlus easily into a PC-based measuring system.
TANGO Plus system integration with AUDITOR light post-processing software
With the combination of the Tango Plus sound level meter and the AUDITOR light post-processing software we offer a powerful solution for measurement, evaluation and report generation of environmental noise. The post processing allows an effective calculation of Rating Noise Levels according to the German TA-Lärm as well as international standards and laws.
The main features of AUDITOR light are:
- Import of Tango measurement values and markers
- Graphical display of long-term measurements
- Extracting, marking and masking of data
- Calculation of Rating Noise Levels
- Report generation
Our full version of the AUDITOR™ software allows the post-processing of all sound level meters & analyzers from SINUS Messtechnik, including Tango Plus.
