Functional Description
The 330500‑07‑00 sensor converts casing vibration into a proportional velocity signal using an internal piezoelectric accelerometer and integrated signal‑conditioning electronics. This configuration ensures high sensitivity to low‑frequency vibration, making it suitable for machinery where casing vibration is the primary diagnostic indicator.
Correct installation is essential for accurate amplitude and frequency response. The sensor should be mounted directly to the bearing housing using approved fasteners or adapters to avoid resonance or false vibration readings. Engineering support is recommended for applications involving high‑temperature zones, non‑standard mounting surfaces, or integration with existing monitoring systems.
