Modular Precision Sound Level Meter
Informacja
odular Precision Sound Level Meter Type 2231 is a Type 1
precision instrument in accordance with IEC 651 regulations.
It can perform a wide range of measurements, and can be used
with a variety of modules. The characteristics of the sound
Level Meter depend on the module that you most recently
loaded into it - the module’s Software, transferred to the
sound Level Meter, adapts the instrument to particular
needs. The nature of the measurements that you require will
determine those needs.
In general, when the sound level, meter receives a signal,
it performs several measurements simultaneously (for
example, Peak and EMS detection). Therefore, you can look at
the Peak and RMS values of the same measurement. A very wide
frequency range of 1 Hz to 70kHz allows measurements in the
infrasound and ultrasound regions.
Depending on the module loaded, the sound Level Meter can
perform several special functions, including automatic
print-out of data at the end of preset time periods. These
print-outs can be in any one of six languages. The sound
Level Meter can also communicate with, and be controlled
from, a computer.
The sound Level Meter has three polarization voltages. This
means that you can use almost any Bruel & Kjaer Microphone.
"With Microphone Type 4133 plus extension cable AO 0027, the
sound Level Meter becomes a Type 0 instrument, in accordance
with IEC 651 recommendations.
Features of the Type 2231 Sound Level Meter include:
■ Fulfils IEC 804 Type 1, relevant sections of IEC 651 Type
11, and ANSI SI .4-1983 Type 1.
■ When used with Microphone Type 4133 and Extension Cable
AO 0027, fulfills IEC 804 Type 0 and relevant sections of
IEC 651 Type 0 I.
WH 24 to 113dB(A)* measuring range (30 to 133dB(A)* with
attenuator) in 7 overlapping sub-ranges.
M 73 dB Pulse range; 70 dB RMS Linearity range.
■ RMS and Peak detection in parallel.
■ Internal memory has back-up battery power which prevents
loss of application Software and data when the instrument is
switched off.
