EPRO A6125 – Dual-Channel Piezoelectric Vibration Monitor
Product Overview
The EPRO A6125 is a dual-channel, case-mounted piezoelectric vibration monitor developed by EPRO Technologies GmbH, now part of Emerson. It measures vibration from piezoelectric accelerometers or velometers mounted directly on machine casings. This module is essential for the CSI 6500 machinery protection system and complies fully with API 670 standards.
The A6125 focuses on case vibration, reflecting machine housing dynamics influenced by rotor movement, foundation stiffness, blade vibration, and adjacent equipment. It is widely used in steam turbines, gas turbines, compressors, pumps, and gearboxes.
