In addition to offering the full range of microphones, accelerometers and acoustic and vibration calibrators you might expect from the worlds secon largest manufacturers of sound and vibration instrumentation, Rion offer two types of product which are unqiuely suited to the automotive industry.
The Rion Acoustical Capacity/Volume Meter has revolutionised the measurement of engine cyclinder capacity. Where the burette method took hours, was messy and needed skilled and experienced practicioners, the Acoustical Capacity Meter takes minutes and measurements can be taken both with the cylinder head off and upon the completed engine.
Rion specialise in highly portable, battery-powered instruments that will measure and/or record accurate sound and/or vibration data in sensible formats on the move. These battery-powered, open-architecture instruments can be used with most standard noise or vibration sensors and store data as comma separated variable files and record signals in standard wav file format.
The RioNote is a tablet-form multi-channel noise/vibration/data platform. The instrument can be connected (wired or wirelessly) to up to 4 measurement amplifiers which can each be up to 4 channels. Rion provide the measurement and data recording tools (wav file recording, FFT, octaves/third octaves, full sound level meter functionality) so the measurements are rock solid reliable. However, the user can develop their own Android Applications on the RioNote to match the exact way they want to work. Full support is available from Rion during this process under the Alliance System.
The Rion DA-21 is a battery-powered portable data recorder which stores up to 4 channels of sound or vibration data as a standard multi-channel wav file.
The Rion VA-12 is a single channel vibration analyser, which can be used to display overall levels of acceleration, velocity and displacement simultaneously or the FFT (in terms of acceleration, velocity or displacement) or the time trace of the signal (like an oscilloscope) and which can simultaneously record a calibrated wav file of the signal that is being measured.
If you need to measure, analyse or record noise in strict accordance with IEC 61672: Class 1, the Rion NL-52 is extremely easy to use. In it's most basic format it is an integrating sound level meter which measures overall sound pressure level. A full range of accessories is available for the NL-52 including microphone extension cables, audio recording of calibrated standard wav files, octaves/third ocatves and FFT narrow-band analysis. If you can accept Class 2 accurace, the Rion NL-42 offers exactly the same functionality as the NL-52 at a considerably lower price.
