Description
Overview
The 330525‑02 Velomitor XA Piezo‑Velocity Sensor is a rugged vibration‑monitoring device developed by Bently Nevada for machinery protection and condition monitoring applications. Designed for use in harsh industrial environments, this sensor provides accurate casing‑vibration measurements where shaft‑based proximity probes are not practical. Its compact, sealed construction ensures long‑term reliability in demanding process facilities.
Functional Characteristics
The sensor is built with a corrosion‑resistant 316L stainless steel housing and an environmentally sealed connector system, eliminating the need for external protective enclosures. The 330525‑02 meets IP65 and NEMA 4X environmental ratings, offering strong resistance to dust, moisture, and chemical exposure.
Key performance features include:
-
Piezoelectric velocity measurement for casing vibration
-
Compact form factor for tight mounting locations
-
Weather‑resistant cable and connector assembly
-
Suitable for pumps, compressors, motors, and fans
-
Designed for general industrial use (non‑radiation‑rated)
This model is part of the Velomitor XA family and integrates seamlessly with Bently Nevada monitoring systems, including the 3300 series.
