Description
Description:
The CE134 444-134-000-405 is a low-frequency (LF) piezoelectric accelerometer manufactured by Meggitt Vibro-Meter. Designed for industrial vibration monitoring, it offers a current-modulated output signal suitable for long-distance transmission. This sensor is ideal for applications requiring reliable and precise vibration measurement in harsh environments.
Application Scenarios:
In a recent project within a chemical processing plant, the CE134 444-134-000-405 was integrated into the monitoring system of a high-speed pump. The accelerometer’s low-frequency response enabled the detection of early-stage mechanical issues, leading to timely maintenance and preventing potential failures. Operators reported enhanced system reliability and reduced downtime, demonstrating the accelerometer’s critical role in predictive maintenance strategies.
