3500/40M 140734-01 Proximitor Monitor

The Bently Nevada 3500/40M 140734-01 is a four-channel Proximitor Monitor from the 3500 Series Machinery Protection System, manufactured by Baker Hughes (Bently Nevada). Its core function is to accept signals from eddy-current proximity transducers (such as the 3300 XL series), condition these signals, and provide critical measurements including radial vibration, axial (thrust) position, differential expansion, and eccentricity. It continuously compares measured values against user-programmable alarm setpoints to protect turbines, compressors, and other critical rotating equipment from catastrophic failure.
