Convergence Instruments, mems based, low budget noise monitoring, complying with Class 1 accuracy.
The Wireless Sound Level Meter Data Logger NSRTW_mk3 is the second generation of Convergence Instrument’s WiFi™ enabled smart integrating sound-level meter/datalogger. It includes a type 1 digital MEMS microphone, an accurate date/time clock, a non-volatile 128 Mb recording memory and wireless connectivity with fast USB and WiFi download.
Running on battery, it can record sound pressure levels and report them through WiFi™ for a week. Connected to an external USB charger it can record and report for months. Its very small size allows it to be attached to or embedded within the monitored equipment.
Every Wireless Sound Level Meter Data Logger NSRTW mk3 purchased is provided with an Individual Manufacturer’s Certificate of Calibration from Convergence Instruments. This all-digital design includes the A, C, and Z weighting curves. It is enclosed in a completely weatherproof casing which is designed for indoors and outdoors applications.. Its highly sensitive Type 1 MEMS microphone has a noise floor of 30 dB-A and is ultra stable with time and temperature variations. The software includes an oscilloscope and spectrum analyzer features, as well as email alarms.
- Complies with the precision requirements of ANSI S1.4 and IEC651 standards – Type I
- Type I precision (bandwidth selectable between 16 kHz and 20 kHz)
- “Z” weighting (in addition to A and C)
- Open TCP/IP protocol to facilitate custom user applications/instrument interface
- Server access via a domain name
- Direct email alarms (no need to transit through the server)
- Fast USB and WiFi downloads
- Real-time recording while connected to PC (Use of the SLM as a high-quality digital microphone at 32 kHz and 48 kHz sampling rates)
- New “universal” Manager application that can manage any instrument in the Noise Sentry RT series
If online monitoring /alarms/auto reporting is not needed there is also an even lower cost solution with the offline dataloggers from Convergence Instruments.
