3500/45-01-00 | 3500/45 | Bently Nevada 2-Channel Monitor

Product Description

The 3500/45 (Part Number: 3500/45-01-00) is a high-precision, two-channel position monitor designed for the Bently Nevada 3500 Machinery Protection System. This module is specifically engineered to process signals from proximity probes and LVDTs (Linear Variable Differential Transformers) to provide continuous, online measurements of axial thrust position, differential expansion, and case expansion. By monitoring these critical parameters, the 3500/45 (3500/45-01-00) prevents catastrophic machinery failure caused by rotor-to-stator contact or excessive thermal growth.

Equipped with sophisticated diagnostic logic, the 3500/45 (Model: 3500/45) ensures that machinery protection setpoints are strictly enforced. It compares processed input signals against user-programmable alarm setpoints and provides real-time relay outputs and 4–20 mA proportional signals for DCS integration. This module configuration includes the Position I/O Module with internal terminations, specifically optimized for Proximitor, RPT, and DC LVDT inputs. Its rugged design ensures reliable operation in demanding industrial environments, maintaining signal integrity even under high-temperature conditions.
