Portable Vibration Meter

Dytran Instruments launched a new portable vibration meter. The model 4190 can be used in conjunction with a hand-held shaker for sensor validation. It converts the vibration signal from a 10 mV/g or 100 mV/g IEPE accelerometer to the PEAK value of the vibration signals generated by these sensors. A built in power supply provides 2 mA of current at +18 VDC compliance. Two rotary switches allow selecting between a 10 mV/g and 100 mV/g accelerometer input and full scale ranges of 2g, 20g and 50g. The 4190 features a large digital front panel meter, a bias test switch to verify proper accelerometer operation, and an output jack for monitoring the output signal of the accelerometer with an oscilloscope. Two replaceable 9V batteries allow for 10 hours of continuous operation.
