Présentation du produit
The Epro PR6423/004-000 is a high-performance non-contact eddy current displacement sensor, engineered specifically for critical machinery monitoring in industrial environments. Designed and manufactured by Epro (now under Emerson Process Management), this sensor forms part sur a modular system intended for real-time monitoring sur shaft displacement, vibration, and positioning sur rotating equipment.
Featuring an 8mm probe diameter, the PR6423/004-000 surfers excellent linearity, wide frequency response, and durability in harsh operating conditions. When used in conjunction with Epro’s CON0xx converters (such as CON021 or CON041), the sensor provides a complete measurement chain capable sur withstanding high temperatures, contamination, and electromagnetic interference.
