The Outdoor Noise Processor mounts on the wall to monitor and record the sound levels. The digital display usually shows the current sound level, but this can be switched off or even set to display the time.
Its purpose is to continuously monitor the sound levels, recording the sound level for download to a computer via memory stick. It can also be linked directly into an existing process control system via the 4-20mA Current Loop or the DC output. For a long term outdoor noise monitor, output to a control system is the most common way of using it.
The SE3-320W has a large internal memory, to which it can store various sound level parameters every second. It can store the Fast or Slow sound level with "A" or "C" frequency weighting. You can select whether it stores all of these parameters or just the ones you need. When you plug a memory stick in the SE3-320W will automatically transfer the measurements on to it. You then plug the memory stick into your computer to load the measurements into the SoundEar software.
The SE3-320W can be linked in to existing monitoring and process control systems, or you can develop your own monitoring system, using either the DC output or Current Loop output.
This is a standard method of electrical signalling, used by many process control systems, with the benefit that the signal is not degraded by voltage drops in the wiring. For more information please visit the Outputs page.
The DC Output from the Outdoor Noise Processor provides the measured sound level over a range of 0 to 10V DC, which can be measured using a basic A-D converter. For more information please visit the Outputs page.
The digital display on the SE3-320W usually shows the current sound level, updating every second. However, it can be set to any of the following:
Turning the display off or displaying the time can be useful if you don't want to show the sound level in decibels.
The Outdoor Noise Processor (order code SE3W-320) is for long term noise monitoring in areas where it may be exposed to the weather or high levels of dust.
When downloaded to a computer you can easily identify the noisy times of day and the limits reached.
This monitor is protected against the weather and dust, rated to IP65. It can be mounted to a wall outside with four screws. A 10m (32 ft) power cable is included, to connect to the indoor power adapter that is also included.
Many process control systems can accept analog signals meeting the 4-20mA current loop standard. The standard unit (order code SE3-320W) has two 4-20mA current loop outputs, which can be configured using the software included.
There is more information on the Outputs information tab.
The SE3-320W Outdoor Noise Processor has two DC outputs that can be used for integration with your own applications. Typically connected to an A/D converter, the sound levels can be monitoring continuously.
For more information about the DC voltage output, please visit the Outputs tab.
The weatherproof noise processor mounts with four screws that are accessible from the front of the case with the front panel removed.
A 10m (32ft) power cable is already fitted to the monitor. It is the white cable visible in the image. This power cable plugs into the 24 VDC power supply that is included. The power supply is not protected against the weather and so should be mounted indoors or inside its own weather-proof enclosure.
The noise monitor can also be provided with additional cables for access to the 4-20mA outputs or the 0-10V DV outputs. Otherwise you can fit cables to these through a weatherproof grommet to the screw terminals inside.
For downloading noise measurements via USB stick, a weatherproof USB socket is fitted to the bottom of the enclosure, between the microphone and power grommet.
The SE3-320 comes complete with a power adapter. This provides the safe low voltage that the noise sign requires.
Extension Power Cable - If you need to run power for a longer distance then you need the POWEX10 extension cable.
With the front panel removed you have access to the four mounting holes, seen at each corner in this image.
The unit is delivered with a 10m power cable already fitted, and sealed through a gland at the bottom of the case. This cable has a connector on the end that connects to the power adapter. If you have another 24 VDC supply available then the connector can be removed and the wires connected to your existing supply. In this case we recommend fitting an inline fuse.
The SE3-320W Noise Processor comes complete with software to configure, download and display the results.
The outputs can be configured to:
The software is included with the SE3-320W at no extra charge. It is designed for all recent versions of Windows. It communicates with the noise processor via the computer's USB port. Downloads and configuration can be carried out via a memory stick, so you don't have to take the processor down from the wall each time.
With a Noise Processor connected to the computer's USB port, the software can show the sound levels in real time.
To download historic measurements it is not necessary to connect the processor to the computer. You can plug a standard USB stick into the sign and it will automatically transfer all its measurements. With the memory stick connected to the computer the SoundEar software will now download the measurements. In the image above you can see the sound levels graphed over a 24 hour period.
Using the software you can set the output from the sign to be either a DC level (0 to 10V) or current loop (4-20mA) for integrating into other logging and monitoring systems. You can also set the minimum and maximum sound levels that are then mapped onto this DC or current loop output. For more information, please visit the Outputs tab.
The Noise Processor stores noise measurements in its internal memory. You can configure it to store a minimal amount of information for longer, or to store everything for a shorter period of time.
For most applications the Noise Processor's internal memory is large enough for more than 18 months storage without download - although of course we would recommend regular download to avoid data loss.
The SoundEar software can configure the sign's digital display to show:
Although the default is to show the sound level, it can be useful to turn this off if it causes confusion (not everybody understands dB) or if it causes people to make noise to see how loud they are!
If you have a Sound Level Calibrator and need to ensure the accurate operation of the Noise Processor then the software deals with this. Connect the SE3-320W Noise Processor to the software, connect a microphone extension cable and fit the calibrator to the microphone. The software Microphone Calibration option will then deal with the process of checking and adjusting.
The SE3-320W Noise Processor has two outputs available. These outputs can be configured to either:
Each of the outputs can be configured to provide:
The range of dB measurement covered by the DC voltage or 4-20mA loop is set using the software.
At the rear of the noise processor (inside the weatherproof box) there is a connector block. This connector pulls out of its socket and contains screw terminals to connect the following:
The Noise Processor includes standard 4-20mA Current Loop outputs. These provide a signal that does not degrade due to resistance, allowing for longer cable runs, limited by the ability to drive the current.
The Noise Processor also includes DC Voltage Outputs that are proportional to the measured sound level. They are ideal for level recorders and input to data logging systems.
There are two current loop / DC outputs on the SE3-320W, so you can select two different parameters to monitor. Both outputs are set to the same measurement range, but you can select different parameters, as described below.
Each output can be one of the following noise measurement parameters:
The overall measurement range of the Noise Processor is 30dB to 120dB. You can process this whole range over the current loop or DC voltage output, or you can select the range of interest.
The standard Outdoor Noise Processor order codes (SE3-320W or SE3-320W-x for multi packs) include everything needed for most applications:
The SE3-320W-x Multi Packs include all these items for each SE3-320W. They also include an NM102 Hand Held Sound Level Meter, which can be used for making quick measurements of sound levels in the surrounding area, and can be helpful when setting the noise processor up.
