990 Test Adaptor

The 990 test adapter inverts and isolates the output signal from 990, 991 and Seismic Transmitters, allowing you to interface our Bently Nevada transmitters to AC-powered diagnostic equipment ( such as ADRE® , oscilloscopes, and portable data collectors) while providing a high input impedance. The adapter inverts the phase of the “ Prox Out” signal 180 degrees ( to match standard vibration signals) , isolates the test equipment output from the transmitter to prevent ground loop problems with the 4-20 mA current loop, and reduces the noise susceptibility of the transmitter dynamic output signal.
