Customized Turbomachinery Monitoring Driver | Emerson PR9350/02-S2

Product Description

Overview

The EPRO PR9350/02-S2 is a proximity probe driver (oscillator/demodulator) from Emerson’s AMS / EPRO PR9350 series. It interfaces with eddy current displacement sensors such as the PR6422 and PR6423 series, converting raw probe signals into standardized voltage outputs representing shaft vibration, axial position, or eccentricity.

The S2 variant provides a special configuration, including adapted output scaling, calibration, or installation adjustments. Therefore, it is ideal for customized turbomachinery monitoring setups in steam turbines, gas turbines, compressors, pumps, and gearboxes. Its API 670 compliance ensures high reliability in critical machinery protection systems, while seamless integration with VM600 and AMS 6500 platforms guarantees efficient monitoring operations.
