MODEL 226 AC STRAIN GAGE CALIBRATOR

MODEL 226 AC STRAIN GAGE CALIBRATOR

Description

The Model 226-002 provides a calibrated sinusoidal signal to your strain gage measurement system.  The precision calibration resistor in series with a modulation signal is connected across the strain gage.  The peak-to-peak value of modulation signal is automatically set to equal the bridge excitation mode.
