The Bently Nevada 3500/40-03-01 Proximitor Monitor is a four-channel module designed for the 3500 Series Machinery Protection System. This module conditions input signals from proximity transducers to provide continuous, high-integrity monitoring of critical machinery parameters including shaft radial vibration, thrust position, differential expansion, eccentricity, and REBAM (Radial Eccentricity and Blade Amplitude Measurement). The 03-01 configuration ensures compatibility with standard Bently Nevada proximity probe systems.
This module is essential for protecting critical rotating machinery, such as steam turbines, gas turbines, centrifugal compressors, and large pumps. It is widely used in power generation, oil and gas, and petrochemical facilities to detect mechanical faults before they lead to catastrophic failure.
