Description
Product Description
Overview
The CON020/91 by Emerson is a precision signal conditioning module engineered for use with EPRO eddy current proximity measurement systems. It functions as the electronic processing stage, converting raw probe signals into stable, calibrated electrical outputs suitable for high-fidelity vibration and displacement monitoring in rotating machinery. This module is an integral component of a three-element measurement chain and is not a standalone sensor.
Measurement System Architecture
A standard configuration consists of:
-
PR642x Proximity Probe (sensing element)
-
ECF Extension Cable (signal transmission)
-
CON020/91 Conditioning Module (signal processing unit)
This architecture ensures uniform calibration across turbines and compressors, maintaining measurement integrity under dynamic mechanical load conditions.
