Upgrade suggestion:
The 3300 series has been discontinued, the Bently Nevada 3300/50 is a direct replacement for the 3500/50:
Advantages: Compatible with the original sensor, with a new "speed change rate alarm" function to prevent acceleration out of control;
Disadvantages: The rack and backplane need to be upgraded simultaneously, and the transformation cycle of the old system is about 2-3 weeks.
