QuantumX MX238B Precision Measuring Amplifier

QuantumX MX238B Precision Measuring Amplifier

Precision module with accuracy of 25 ppm

Measurement signals need to be made available with increasing precision and, at the same time, with high stability to fully utilize the potential of static measurements in calibration tasks, The new compact QuantumX MX238B two-channel precision module with 0.0025 accuracy class (25 ppm) is ideal for highly precise measurements with full bridge strain gauge based transducers. At the same time, it is compact and small and thus suitable for on-site servicing. Patented HBM background calibration ensures uninterrupted measurement, even during the comparison with the internal calibration signal. Seamless integration with field buses or time synchronization with other systems via Ethernet PTPv2 allow for convenient integration with the cutting-edge QuantumX data acquisition system.In addition, HBM provides all the components required for setting up reference measurement chains: Reference transducers (torque, force, pressure), the QuantumX MX238B measuring amplifier and suitable catman software.
