Bently Nevada 3500/50 133388-02 Tachometer Module

The Bently Nevada 3500/50M is a two-channel tachometer module designed to measure the speed of rotating shafts. This precision monitoring device accepts input from proximity probes or magnetic pickups to determine rotative speed, rotor acceleration, and direction of rotation, comparing these measurements against user-programmable alarm setpoints for comprehensive machinery protection.

• Configurable monitoring options including speed monitoring with alarming
• Zero speed notification and rotor acceleration alarming
• Reverse rotation notification and speed band alarming
• Supplies conditioned Keyphasor signals to other monitors in the rack
• Peak hold function stores highest forward/reverse speed reached
• Tracks number of reverse rotations with user-resettable peak values
• Eliminates need for separate Keyphasor signal module

The 3500/50M can be configured using specialized software for various monitoring tasks, making it suitable for diverse industrial applications where precise rotational speed monitoring is critical for equipment protection and operational efficiency.
