Integration and Configuration Considerations
Connectivity includes USB-C, Wi-Fi, Bluetooth and Ethernet. The NA41 outdoor protection device provides an IP65-rated wind and rain shield, while the NA43 adds an electrostatic excitation device. Confirm the complete monitoring architecture, power, protection and data-transfer requirements before ordering.
Selecting the Measurement Chain
Accurate acoustic measurement depends on the complete signal chain. Therefore, confirm the microphone field type, sensitivity, dynamic range, preamplifier, connector, cable, constant-current supply, data-acquisition input and calibration method as one system. Metromatics can help review these interfaces before quotation.
