Product Introduction

The 3500/40 125672-01 Proximity Monitor is a specialized industrial monitoring module designed to measure shaft displacement, vibration, and position using non-contact proximity probe technology. Developed for use within the 3500 machinery-protection platform, it delivers continuous monitoring of critical rotating equipment such as turbines, compressors, pumps, and motors.

With advanced signal-conditioning circuits, the 3500/40 captures precise displacement data and translates sensor input into actionable alarms. Its high-resolution processing ensures stable performance in harsh industrial environments, even where electrical noise, mechanical shock, and temperature fluctuations are common.

This model is widely applied in predictive maintenance, equipment reliability programs, and machine-protection architectures. It is ideal for both new installations and retrofit upgrades for industrial plants requiring dependable shaft-motion monitoring.
