Targeting mechanical engineering R&D applications, single-channel VersaLog BR measures machinery-generated stress and supports 4/6 wheatstone bridges by providing voltage excitation, excitation voltage compensation, and low-level signal amplification. Input voltage measurement range of -8 to +8 mV accommodates common bridges with sensitivity of up to 3 mV/V. Along with 16-bit ADC and programmable input range, features include 4 MB flash memory, alarm, and 20 msec to 12 hr sampling intervals.
