Dytran Instruments 4190 portable vibration meter

Dytran Instruments has announced the 4190 portable vibration meter for field testing accelerometers, which can be used in conjunction with a handheld shaker for sensor validation.

The meter 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.

It has a built-in power supply that provides 2 mA of current at +18 VDC compliance to operate either a 10 mV/g or 100 mV/gIEPE accelerometer.

Two rotary switches allow the user to select between a 10 and 100 mV/g accelerometer input and full scale ranges of 2, 20 and 50 g.

It 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 9 V batteries allow for 10 h of continuous operation.

Its features include: reads Peak vibration in Gs on a large digital front panel meter; built-in signal conditioning for 10 mV/g and 100 mV/g accelerometers; LED indicator to confirm accelerometer connection; and low-battery LED indicator.
