📘 Product Overview: 3500/42M (140734‑02 + 135489‑02)
Description
The 3500/42M (with component part numbers 140734‑02 + 135489‑02) is a dual-channel proximity probe interface module used in critical machinery protection systems. It accepts raw signals from non-contact eddy-current probes and conditions them into usable vibration and displacement data. The paired component 135489‑02 is typically a system accessory or signal isolation hardware, enhancing module reliability and field performance.
It is part of a modular rack-mount system designed for 24/7 operation in demanding environments such as turbines, compressors, and rotating industrial machinery. The 3500/42M ensures high signal fidelity, system integration compatibility, and robust performance under harsh conditions.
