Interfacing and System Integration - AC Output

The AC Output from these sound level meters takes the raw signal from the microphone, amplifies it and applies some limited filtering. This output can be used for digital recording systems for example, or it can be sampled for post processing and further analysis. These meters meet the international sound level meter standards to Type 1 or Type 2, so the correct processing of the output signal will give a very accurate sound level reading.

Which Meter?

If you are unsure about the best meter for your application then please contact us on info@noisemeters.com. If you let us know about your noise measurement and interfacing requirements we will be able to recommend the most suitable and cost effective meter.

Mic Extension Cable

The CEL620 is the lower cost meter. The main limitation is that it comes with a fixed preamplifier (microphone stem), so it cannot take a microphone extension cable. If you are able to mount the sound level meter close to the monitoring location then this should not be an issue. Otherwise, the CEL632 meter will be better as we have microphone extension cables of 5m, 10m and 30m length.

Data Logging

Both of these meters can store measurements for download to a computer. The CEL620 series meters connect to a computer without the need for additional software, accessed like a memory stick with the measurements in CSV text files. The CEL630 series have more advanced measurement and automatic timer options.
