1. Product Title

BENTLY NEVADA 1701/15‑ FieldMonitor Proximitor Input Monitor Module

2. Product Overview

The 1701/15 is FieldMonitor series proximitor input monitor module by Bently Nevada, designed for eddy‑current proximity probe signal conditioning for rotating‑machinery protection systems. It receives raw displacement signals from proximity probes, executes amplification, linearization and filtering, outputs standardized 4‑20 mA analog signal and supports Modbus‑RTU RS485 communication. Equipped with relay alarm outputs for shaft displacement monitoring of turbines, compressors and large rotating equipment. Rugged enclosure adapts to harsh field installation environment, realizing real‑time shaft position monitoring and early fault warning for critical rotating assets.
