This advanced vibration meter utilizes a state-of-the-art ICTrue RMS to DC converter to transform the input, from standardized Dytran LIVM
industrial accelerometers, to a DC voltage
displayed on a large analog front panel meter calibrated
directly in g’s RMS.A 4 position
rotary switch and a choice of two sensorsensitivities (10 or 100 mV/g) provide 6 ranges from 1 g
to 500 g’s full scale.A self contained DC current source supplies power to theLIVM (Low Impedance Voltage Mode) accelerometer.The Model 4151HL has a variable High Limit set pointcontrolled by a front panel trimpot. Rear panel terminal blockhas normally open/normally closed option to make or break
a circuit. Red LED indicates when high limit has been exceeded.Displays True RMS value of vibration waveform, irrespectiveof wave shape. It has a wide frequency range with four switchselected ranges. The meter provides a 0-10 VDC output signal
for each range. The 0-10 VDC output is available at a BNCjack on the rear panel for use in a control loop. A “Monitor”jack at the front panel allows monitoring of actual accelerometerwaveform with an
oscilloscope. A push button on the front
panel checks the condition of accelerometer and cables.The unit may also be used as a four range True RMS voltmeter(.1, .5, 1.0 & 5.0 Volts RMS F.S.). This meter can be easilyrack mounted with a single thumbscrew. The model 4151HL
is suitable for laboratory, R & D and OEM applications.
