The Expert Logger device is being launched in three versions, capable of processing 16, 32 or 46 analogue input channels. Up to eight digital inputs/outputs and one SDI12 interface are also available depending on the version. The main areas of application include product testing, environmental measurement technology, laboratory data acquisition, research and development, and trials and testing.
All analogue inputs are galvanically isolated from each other. A 24-bit A/D converter ensures fast, precision sampling rates of up to 50 measurements per second per channel. The devices are maintenance and noise free due to the absence of electromechanical components (such as relays) that are prone to wear and tear.
All Expert Loggers are equipped with internal 4 GB memories that can independently store up to 100 million measurement values with date and time stamps. Storage capacity can be extended as required via external USB or LAN storage (NAS). Online measurement data or the contents of the data memory can be transmitted to the internet via an integrated WLAN or UMTS module.
The Expert Logger is also equipped with an energy-saving "sleep function" for automated switching off during breaks in measuring. Independent operation is possible using batteries, rechargeables or solar panels. The Expert Logger can communicate as standard via CanBus, ModBus and ProfiBus. Internal software channels such as calculation channels, limit values and integrators enable online evaluation of measurements and the logging of meaningful data.
Users can quickly and effectively operate the Expert Logger using the ProfiSignal Go software that is included free in delivery. ProfiSignal Go can be used to portray measurement data in trends and to carry out detailed analyses. The software also enables fast ASCII exporting of measurement data for Excel or for conversion into TDM format.
