Emerson A6125 Dual-channel Case Piezoelectric Vibration Monitor
The Case Piezoelectric Vibration Monitor is designed for high reliability for your plant's most critical rotating machinery monitoring case vibration from accelerometer sensors. This 1-slot monitor is used together with other CSI 6500 monitors to build a complete API 670 machinery protection monitor. Applications include steam, gas, compressors and hydro turbo machinery.
The main functionality of the Case Peizoelectric Vibration Monitor is to accurately monitor case vibration and reliably protect machinery by comparing vibration parameters against alarm setpoints, driving alarms and relays.
Case piezoelectric vibration sensors, sometimes called case absolute (not to be confused with shaft absolute), are accelerometers, or velometers, with the output in acceleration or velocity. The case vibration monitor provides vibration monitoring for the bearing case in g’s acceleration or velocity, mm/sec (in/sec). Since the sensor is mounted on the case, the resultant vibration of the case can be influenced by many different sources including rotor movement, foundation and case stiffness, blade vibration, adjacent machines, etc.
When replacing field sensors, many seismic sensors are being replaced with piezoelectric-type. The 6125 monitor is designed for the newer piezoelectric style sensors.
Case measurements are common in nuclear power applications. Case measurements with piezoelectric sensors are also common for rolling element bearing machines and gearboxes. Emerson recommends the piezoelectric sensor and piezoelectric sensor monitor for use when updating both field sensors and monitors.
The CSI 6500 is an integral part of PlantWeb® and AMS Suite. PlantWeb provides operations integrated machinery health combined with the Ovation® and DeltaV™ process control system. AMS Suite provides maintenance personnel advanced predictive and performance diagnostic tools to confidently and accurately determine machine malfunctions early.
