BENTLY NEVADA 3300/20-11-01-02-00-01 Dual Thrust Position Monitor

Description

The BENTLY NEVADA 3300/20-11-01-02-00-01 Dual Thrust Position Monitor is a specialized module within the 3300 Series condition monitoring system, designed for continuous measurement and monitoring of shaft axial position related to machine tool axial clearance. Equipped with two independent monitoring channels, it can simultaneously track either the same thrust collar or two distinct positions on a single shaft, significantly enhancing monitoring accuracy and operational reliability. A core function is early thrust bearing fault detection, which supports proactive equipment maintenance to prevent unexpected downtime. It delivers high-precision, high-stability measurements by using proximity probes to detect gap voltage, directly reflecting thrust bearing position relative to thrust bearing clearance. To address potential false alarms caused by sensor faults such as out-of-range gaps, the device supports configuration with a two-probe AND voting logic, where alarm relays activate only when both sensors reach or exceed set alert thresholds. This monitor is part of a mature solution for rotating machinery condition monitoring, suitable for applications including vibration, displacement, keyphasor, and speed measurement, and complies with industrial standards such as API 670.
