The data logger with USB interface is used for permanent monitoring of the sound level. In addition to storing the measured values, the sound level data logger is able to display the measured values ​​on a display and output them as a 4 ... 20-mA analog value. The sound level data logger has a wide measuring range of 30 ... 130 dB. Frequency weighting is done in A or C depending on the selected measurement mode. Alternatively, the sound level data logger can measure the sound level in fast or slow mode. 

The measured values ​​are stored by the data logger with USB interface as an Excel file on a memory card. This has the advantage that after a measurement, the SD memory card can be easily removed from the sound level data logger and the data can be evaluated without additional software. The PCE-SLD 10 sound level data logger is powered by 6 x 1.5V AAA batteries. For long-term operation, an external plug-in power supply is included in the sound level data logger. 

The data logger with USB interface is used wherever the noise level has to be permanently monitored and a controller is to carry out further actions. In a production hall, for example, this can be the visualization of the sound level on a large display. Or, in conjunction with switchgear, closing windows and doors when the sound level is exceeded.
