Description

EPRO PR9376/010-011
(Vibration Monitoring Module for Turbine and Rotating Machinery Protection)

Product Overview

The EPRO PR9376/010-011 is a 4-channel vibration and position monitoring module designed for critical machinery protection in power generation, oil and gas, and industrial applications. Part of EPRO’s PR 9376 series, this module interfaces with proximity probes (eddy current sensors) and accelerometers to monitor radial vibration, axial displacement, and speed of turbines, compressors, pumps, and other rotating equipment. Compliant with API 670 and ISO 10816 standards, it ensures early fault detection and operational reliability through advanced signal processing and alarm logic.
