Product Introduction
The Epro PR6424/010-110+CON021 is a high-precision, non-contact eddy current proximity sensor system designed for the measurement of shaft displacement, vibration, and axial position in rotating machinery. Developed by Epro, a reputable brand under the Emerson Process Management umbrella, this sensor is widely used in critical industrial applications where reliable condition monitoring is crucial. It comes equipped with the CON021 converter, forming a complete probe-converter pair that ensures accurate signal processing and output.
This model features an 16mm tip diameter, making it ideal for use in environments with medium-sized shaft diameters, typically found in turbines, compressors, pumps, and other dynamic equipment. It offers rugged construction, high vibration resistance, and excellent immunity to harsh environmental factors such as oil, dust, and temperature fluctuations.
