3300/50 is a legacy Bently Nevada 3300-series tachometer monitor family.
3300/50 provides one monitor channel and two accepted transducer inputs.
3300/50 supports supported 3300, 7200 or 3000 proximity probes, or magnetic pickups.
3300/50 provides speed/acceleration indication, recorder output and an Alert relay according to the ordered mode; the 3300/50 is not an overspeed-protection device.
3300/50 belongs to the 3300 monitoring system, which Bently Nevada classified as obsolete in March 2014; limited repairs were possible only through 2017.
3300/50 should not be selected from the base model alone. The inventory value 3300/50 omits mode, relay, approval and barrier options, so the complete suffix must be read from the unit nameplate.
Before installing or replacing 3300/50, verify the complete nameplate number, rack generation, input transducer, relay module, barriers, approvals and field wiring. Do not represent 3300/50 as a speed-control or overspeed-protection system.
3300/50 is covered at family level by Bently Nevada document 141512-01 Rev. H.
Send the complete component and matching system part numbers, required electrical length, quantity, target material, approval requirements, destination and clear label photos. Availability and condition will be confirmed before quotation.
