DMP41: the most precise amplifier in the world for strain gauge-based measurements

The DMP41 digital highest-precision measuring instrument is ideally suited for calibration tasks because of the following characteristics:

• Long-term stability: DMP41's high long-term stability has been proven in many tests by HBM. They confirm that already DMP39, the predecessor model of DMP40 and DMP41, has maintained the ±5 ppm error band for a time period of over 35 years. The long-term stability offered by DMP41 is unique.
• Electromagnetic compatibility: DMP41 offers significantly higher immunity to electromagnetic interference than the predecessor devices, withstands electric field strengths of up to 10 V/m while maintaining its initial measuring accuracy of 5 ppm. Under these conditions, only a value of 50 ppm could be guaranteed with the predecessor system DMP40.
• Automatic compensation for cable conditions: Due to the cable length, there is complete compensation for voltage loss. It is automatically performed by the amplifier with transducers in 6-wire circuit.
• Background calibration: DMP41 offers the patented 'Background calibration' function with continuous LIVE measurement.
• Versatile interfaces: DMP41 offers a choice of USB, Ethernet and, if required, also RS-232 interfaces and can thus be easily integrated with any laboratory environment.
• Flexible filter functions: The powerful integrated digital signal processor (DSP) allows comprehensive adaptation of the filter parameters to the specific requirements of the measurement task. Users can select from 13 filter frequencies with Bessel and Butterworth characteristics.
• Convenient user interface: The DMP41 offers users flexible control via touchscreen. Control via keyboard or PC client is also possible.
• Ease of use: Toggling between the two principal operating modes 'Measure mode' and 'Setup mode' is easy via the touchscreen or the F1 button at the housing, via a connected USB keyboard or the PC client included in the scope of supply.
