Description

The 330525-01 is a Velomitor XA (eXtended Application) Piezo-velocity Sensor configured with Option 01 for CSA/NRTL/C hazardous area approval. This sensor serves as a ruggedized version of the Bently Nevada 330500 series, specifically engineered for challenging industrial environments where standard mounting housings may be impractical or unavailable. Its construction features a 316L stainless steel case and a weatherproof connector system that meets IP-65 and NEMA 4X requirements when properly installed with a mating extension cable.

Designed for shaft vibration and machine casing monitoring, this transducer requires a compatible mating extension cable to maintain its environmental sealing. The device operates as a seismic transducer, converting vibration velocity into an electrical signal for integration with Bently Nevada monitoring systems. It is intended for use in applications such as pumps, fans, and compressors where casing-mounted vibration measurement provides reliable data on machine health.

Features

  • Option 01: CSA/NRTL/C hazardous area approval certification.
  • 316L stainless steel housing for corrosion resistance in harsh industrial environments.
  • Weatherproof design meeting IP-65 and NEMA 4X standards when used with appropriate interconnect cables.
  • Hermetically sealed 2-pin Mil-C-26482 connector interface.
  • Wide operating temperature range from -55 degC to +121 degC.
  • Broadband frequency response from 4.5 Hz to 2,000 Hz.

Applications

  • Critical machinery vibration monitoring (pumps, fans, blowers, motors).
  • Applications requiring unhoused transducer mounting.
  • Moist or wash-down industrial environments.
  • Hazardous area installations requiring CSA/NRTL/C compliance.
