Vibration Monitoring System · Vibration Monitoring
PCB Piezotronics PCB-MAR-16ch 4-20mA is a shipboard unit in the Vibration Monitoring group, classified in the source as Vibration Monitoring System. It is normally installed on rotating machinery with sensors mounted at bearings, casings or shafts and processing units in local or central control cabinets. Its primary duty is to detect abnormal vibration and support condition monitoring of engines, turbines, pumps, compressors, gearboxes or shafts. In service it interfaces with accelerometers/proximity probes, tachometer references, signal conditioners, monitoring racks and the vessel automation/alarm system. Compared with neighboring entries in the same product family, this record is the exact PCB Piezotronics PCB-MAR-16ch 4-20mA variant; the model designation should be retained unchanged when matching onboard documentation and spares. For exact limits, settings, test values and approved maintenance criteria, refer to the manufacturer documentation for the exact figure.
