The Ranos product range consists of two high accuracy, wireless outdoor sound level meters and cloud applications suitable for permanent and temporary installation anywhere around the worldnwithout a wired power or data connection.
DSS supply the Ranos dB in a class 1 and a class 2 measurement accuracy version. The Ranos dB is powered by solar energy, works fully autono-
mously and has LoRa connectivity. This is why you can use this stateof-the-art device anywhere in the world. The housing is made of recyclable ABS material and is completely waterproof.
The Ranos dB 1 measurement accuracy is according to IEC 61672-1:2014 class 1, with a linear dynamic range of 43-120 dB(A).
The Ranos dB 2 measurement accuracy is according to IEC 61672-1:2014 class 2, with a linear linear dynamic range of 40-120 dB(A).
This means that all measurement specifications and/or features that are required by the standard are present. The performance has been validated by an accredited lab using IEC 61672-3:2013 testing procedures.
The measurements and calculations run continuously (at a bit depth of 24 bit and a sample rate of 48 kHz), this is necessary for accurate time-averaged continuous sound level measurements and for minimum/maximum sound level measurements.
There are no physical differences between the Ranos dB 1 and Ranos dB 2, the only difference is that the dB 1’s microphone is factory calibrated and corrected individually using a 200 coefficient FIR filter.
The Ranos products use the LoRa / LoRaWAN radio communication platform and support the EU868, US915 and AS923 frequency plans. It supports Class C networks, allowing the cloud server to send direct messages to the Ranos dB. LoRa’s low power consumption and long range enables use in remote locations. The available bandwidth is low, but more than enough for the majority of applications.
