Product Introduction

The Bently Nevada 3500/40-03-01 Proximitor Monitor is a high-accuracy dual-channel monitoring module designed as part of the Bently Nevada 3500 Machinery Protection System. This advanced unit continuously measures and processes proximity probe signals to detect critical parameters such as shaft vibration, thrust position, and radial displacement in rotating machinery.

The 3500/40-03-01 integrates advanced electronic filtering and conditioning circuits that convert probe voltage signals into precise engineering units, allowing real-time monitoring of equipment condition. With its dual independent input channels, each can be configured separately, enabling flexible monitoring setups for various machine types like turbines, compressors, motors, and pumps.

This monitor is fully compatible with Bently Nevada’s 3300 and 3300 XL proximity probe systems, ensuring standardized integration across industrial assets. It is widely recognized for its exceptional reliability, high sensitivity, and fast response, providing critical insights into machinery health for predictive maintenance and protection.
