Rion DA-40 Data Recorder

8 Channels of data acquisition on the move. Quick, simple, flexible, portable, battery-powered and storing data in a standard file format to portable media that can be opened and analysed without recourse to specific bespoke software. Itís very easy to use too. When you choose a DA-40 for in-situ data acquisition you will be storing data long before you would have figured out how to get started with most data acquisition systems. The DA-40 records wav files (up to 8 channels) onto compact flash cards. Input and analogue output are via standard BNC connectors and CCLD line drive accelerometers can be connected directly. Designed for the rigours of in-situ use, the DA-40 is perfect for measuring noise and vibration inside vehicles and in other locations where you canít practicably or would prefer not to attach sensors directly to the fixed system you are going to use for analysis.
