FAQ
Q: What differentiates the 330525‑02 from the 330530 radiation‑resistant model A: The 330525‑02 is designed for general industrial environments, while the 330530 is engineered for radiation‑intensive applications.
Q: Does the sensor require an external housing A: No. Its weatherproof connector and sealed stainless‑steel body eliminate the need for additional enclosures.
Q: Can it be used for shaft vibration A: No. Velomitor sensors measure casing vibration; shaft vibration requires proximity probes.
