These are DC exciting dynamic strainmeters with high frequency response of 200kHz(DC-96A) and 500kHz(DC-97A). Bridge excitation can be selected between constant voltage and constant current. When using the constant current excitation, there is no sensitivity decrease due to the cable resistance between the strainmeter and the strain gauge type transducers or bridge box. One unit is for one measurement channel, and two or more units can be installed in an exclusive case or rack to make a multi-channel system. Features Wide frequency response range DC-96A: DC~200kHz, DC-97A: DC~500kHz Digital sensitivity setting method Electronic automatic balancing Excellent zero stability of 0.5×10-6 strain/°C Usable as DC amplifier Bridge excitation is switchable between constant voltage and constant current Dual output Built-in low-pass filter and high-pass filter External control possible for balancing and calibration signal output Dual power supply of AC and DC
