Structure-borne sound sensors, which have a very high bandwidth, are used to monitor grinding processes
There are all kinds of special measuring devices for structure-borne sound sensors. However, process monitoring usually requires a flexible measurement data acquisition system that can be used not only for such specialised sensors, but also covers a wide range of additional sensor connections. Fast and slow measurement channels should also be available. In addition, software is required that enables the parameterisation of the hardware, the display of the measurement signals and the storage of the data on a local hard drive. LTT offers the ideal solution for this!
The high-precision analog inputs are sampled by a 24-bit AD converter with up to 4 MHz sampling rate per channel. Each measurement input can be individually configured via software to connect the following sensors or measurement signals: Volt, Current, Charge, ICP®/IEPE, Strain Gauge (full, half and quarter bridge), LVDT and Resistance measurement (including PT100, PT1000, etc.). In addition, the LTT24 can also sample pulse/counter signals at 832 MHz, for example to derive angular velocity, etc. from a rotary encoder.
Data analysis can usually be covered by software packages such as MATLAB. Likewise, however, a software interface can also be provided via LTTpro if a custom data analysis is to be written.
