Long Term Proven and Optimized High-Precision 225 Hz Carrier Frequency Technology in a Modern and Universal Data Acquisition System

• Abstract:

  The maximum resolution when measuring transduc- ers, which operate on the strain gage principle, is physically limited. The legendary high precision instruments of the DMP series with a high accuracy class of 0.0005 (5 ppm) reach this physical limit. Close to the accuracy class of the DMP series, the “…38”-devices of HBM archive the 0.0025 (25 ppm).
  HBM introduces a new amplifier in this “…38” series, the QuantumX MX238B. The MX238B maintains the well-known and proven 225 Hz carrier frequency technology combined with the pa- tented background-calibration function of the high precision ampli- fier DMP41 in a modular and compact data acquisition system.
