        Features:

        • Interface Between Mechanical Vibration Sources and Condition Monitoring Systems
        • Combines Capability of Piezoelectric Sensing with Wide Frequency Response
        • Operates in Conjunction with VM600 and Compatible Vibration Monitoring Platforms
        The CA306 144-306-000-321 continuously converts mechanical vibration energy into proportional electrical signals through its integrated piezoelectric crystal assembly, delivering these signals through standard coaxial cabling to support real-time monitoring of bearing conditions, gear mesh frequencies, and structural resonances. Seamless signal integrity is standard with the CA306 144-306-000-321, however using an optional integral electronics configuration will allow direct compatibility with constant current powered data acquisition systems in the event of long cable run installations.

        The CA306 144-306-000-321 provides essential sensing functions common to the entire monitoring loop, and is a critical component of the protection path, directly affecting the accurate, reliable detection of mechanical anomalies in the overall machinery system. One or multiple CA306 144-306-000-321 accelerometers are required per machine train depending on the desired measurement point coverage. The CA306 144-306-000-321 occupies minimal mounting space on the machine casing and is always located at the bearing housing positions (radial and axial measurement points, the dedicated vibration monitoring locations).

        For Dual Path Monitoring applications, the machinery protection system requires a second CA306 144-306-000-321 accelerometer module installed at the redundant measurement position. In addition to standard single sensor operation, the redundant configuration also performs cross-verification. The dual sensor configuration executes validation using the internal circuitry specified in the monitoring system options.

        The CA306 144-306-000-321 Vibro-Meter Piezoelectric Accelerometer may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
