Traveller CFM
Traveller CFM (ET1CFM) is a very compact, high performance data acquisition and analog signal conditioning system.
The Traveller CFM system can be used for static and dynamic applications in experimental stress analysis, e.g. to measure analog signals from strain gauges in all common bridge configurations, strain gauge based transducers, potentiometers and general voltage sources, and also to measure asynchronous digital signals up to 4 bits from any type of sensors with digital output. The system uses one connector for each analog channel to simplify the wiring, thus reducing wiring errors and potential damage.
The Traveller CFM with its possibility of wireless data transfer is an excellent choice for mobile applications on board of any kind of vehicles, aircrafts and sea-going crafts, moving machinery, and the like.
Using a special "ESAM" software, the ET1CFM system allows for configuration and control of all parameters of each individual conditioning channel, A/D converting mode, trigger mode, sampling frequency and data transfer from the host computer via USB communication interface, thus reducing the time and risk of faulty configurations and connections. This software works flawlessly under Windows®2000 and Windows®XP. ET1CFM was designed for excellent shock and vibration resistance consistent with EMI and RFI.
Features
- Measurement of signals with frequency band up to 5000 Hz (in SGA1D module only).
- Software selectable sampling frequency rate from the range 0.007 to 100000 samples/sec for each analog channel.
- Optional Remote Control Unit (RCU), including keyboard and 2 x 20 characters low power LCD display, with possibility of software selectable two different highlighting methods of LCD background.
- Up to 32 inputs of conditioned analog channels in one single housing cabinet.
- High speed, high performance USB 2.0 type interfaces to transfer data or commands to or from ET1CFM.
- High speed Compact Flash (CF) card interface to store system configurations and converted data stream in Windows® compatible file format (total capacity up to 2 GB).
- Built in PCM system ENCODER allows for data transfer over long distances using cables or telemetry transmitters (optional).
