Series IV Sound Level Microphone
(Part No. 720A5101)
Introduction
The Series IV Sound Level Microphone can perform unattended
monitoring of noise, such as building activities, construction,
traffic, and mining operations. It is now possible to combine noise
and vibration monitoring on the same unit, making the Minimate
Pro4™ or Minimate Pro6™ a cost effective and flexible monitor
for these applications. The microphone ships with a microphone
stand and windscreen.
The Instantel Sound Level Microphone meets the requirements
for IEC Class 1, which includes A and C weighted specifications.
It has a measuring range from 30 to 140 dB with a fast or slow
response. It is also capable of recording the unfiltered response in
one of two ranges, +/- 25 Pa or +/- 100 Pa. The record mode can be
set to Manual trigger, Waveform (records up to 9000 seconds once
a preset trigger level has been exceeded), Histogram (with intervals
from 2 seconds to 1 hour) or Histogram-Combo (Compliance mode
only, this combines histogram and waveform monitoring at the
same time).
In the Blastware® Advanced Mode setup, it can also trigger and record unfiltered sound clips up to 90 seconds long. The
resulting data file can then be played back in the Blastware Advanced Mode to help determine the source, or it can be further
processed, including third octave frequency analysis.
The microphone connects directly to the overpressure channel of the Minimate Pro4 or Minimate Pro6. For additional
flexibility, the Minimate Pro6 is capable of monitoring two Sound Level Microphones at the same time using the Blastware
Advanced mode. These microphones can be connected directly to the unit or using an extension cable up to 75 meters (250
feet) long.
