Description

The A6125 Case Piezoelectric Vibration Monitor is designed for high-reliability monitoring of critical rotating machinery, using piezoelectric accelerometer sensors. It is part of the Emerson CSI 6500 series, forming a complete API 670 machinery protection system. Suitable for steam turbines, gas turbines, compressors, and hydro-turbomachinery, it accurately monitors case vibration and triggers alarms based on predefined setpoints.
