System Integration and Interfacing

Many of the sound level meters and noise monitors we offer have the ability to output their results, making it possible to link them to an existing monitoring system or to develop custom software. Meters are available with the following outputs:

DC voltage proportional to the sound level
Current loop 4-20mA proportional to the sound level
AC output for recording or detailed analysis
RS232 serial interface

If you need more detailed information about interfacing with the sound level meters then please call or contact us by email. We have engineers available with experience of interfacing with these meters who can offer advice and support.

DC Voltage Output

This type of output provides a DC voltage that is proportional to the measured sound level.

4-20mA Current Loop

Current loop is a common way of interfacing with process control systems.

AC Output

The audio signal from the microphone, amplified but otherwise unprocessed. For recording and analysis systems.

RS232 Output

Standard RS232 serial link, with noise measurements sent as text/csv format for simple decoding.
