Overview Manuals Specifications Applications Communication & Connectivity Safety & Compliance

Features:

  • Interface Between the Machine Surface and 3300 NSv Proximitor® Sensor System
  • Combines Capability of Displacement Detection with Chemical Resistance
  • Operates in Conjunction with the 3300 NSv Transducer System and Standard 3500 Monitoring System
The 330901-00-40-10-02-05 operates as the NSv Proximity Probe in a 3300 NSv transducer system, providing reliable displacement measurement of rotating machinery components. It continuously detects eddy current variations across 0.5 to 2.5 mm linear range while maintaining signal accuracy through PPS probe tip and non-armored cable construction. Seamless signal transmission is standard with the 330901-00-40-10-02-05, however using an optional CableLoc™ design will ensure 220 N (50 lb) pull strength at the connection point in demanding industrial environments. The 330901-00-40-10-02-05 has made improvements in several areas over previous RAM probe designs in addition to incorporating superior chemical resistance capability within the 3300 NSv system.

The 330901-00-40-10-02-05 provides essential sensing functions common to the entire transducer system, and is a critical component of the measurement path, directly affecting the accuracy and reliability of the overall vibration monitoring system. One 330901-00-40-10-02-05 probe is required per measurement channel depending on the desired monitoring point. The 330901-00-40-10-02-05 occupies no rack slots and is always mounted directly on the machine bearing housing (typically in a 1/4-28 UNF threaded mounting position).

For complete system operation, the 3300 NSv system requires the 330901-00-40-10-02-05 proximity probe to convert mechanical displacement into electrical signals. In addition to standard vibration measurement, the 330901-00-40-10-02-05 configuration also performs mechanical interchangeability. The 330901-00-40-10-02-05 probe assembly executes compatibility using the ClickLoc™ gold-plated connector specified in the probe specifications. Using this method, the proximity probe continually ensures connection integrity with 50 lb locking force. If the system detects that the probe signal is compromised (outside configured sensitivity of 7.87 V/mm or resistance tolerance of 7.45 Ω ± 0.50), it will indicate a fault condition in the monitoring system and require probe inspection.

The 330901-00-40-10-02-05 Bently Nevada NSv Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The 3300 NSv proximity probe, such as the specific model 330901-00-40-10-02-05, represents an advancement in eddy-current sensing technology. It is part of the comprehensive 3300 XL NSv Proximity Transducer System and is designed to be mechanically and electrically interchangeable with legacy 3300 RAM probe systems.

The physical construction of the 330901-00-40-10-02-05 probe is engineered for durability and reliable signal transmission. It features a 1/4-28 UNF thread on an unarmored case, allowing for standard installation.  Electrical connections are made via gold-plated brass ClickLoc connectors, which lock into place to prevent loosening and ensure optimal conductivity.

For protection in industrial environments, the 330901-00-40-10-02-05 incorporates several sealing features. An internal Viton O-ring is designed to seal differential pressure between the probe tip and its case. For external protection at connection points, the use of optional connector protectors is strongly recommended. 

When integrated into a 3300 XL NSv system, the 330901-00-40-10-02-05 probe works with a compatible extension cable and a 3300 XL Proximitor sensor to form a complete monitoring channel. This system delivers highly accurate measurements of shaft vibration, position, and runout.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Is the 3300 NSv probe model 330901-00-40-10-02-05 compatible with my existing 3300 RAM system wiring?
Yes, absolutely. The 3300 NSv probe, including model 330901-00-40-10-02-05, is designed to be fully mechanically and electrically interchangeable with the previous generation 3300 RAM proximity probes and extension cables. You can directly replace a RAM probe with this NSv model without changing the existing cable or proximitor, benefiting from its enhanced chemical resistance and performance.
How does the CableLoc design in the 330901-00-40-10-02-05 probe improve reliability?
The patented CableLoc design is a critical durability feature. It securely attaches the coaxial cable to the probe body of the 330901-00-40-10-02-05, providing a certified pull strength of 220 N (50 lbf). This prevents the cable from being accidentally detached or from having its internal connections strained during installation or maintenance, ensuring long-term signal integrity and mechanical robustness in the field.
The datasheet mentions a Viton O-ring seal for model 330901-00-40-10-02-05 but states it's not pressure tested. Can I use it in a pressurized housing?
The 330901-00-40-10-02-05 probe incorporates a Viton O-ring designed to seal differential pressure between the probe tip and case. However, as a standard product, it is not individually pressure tested before shipment. For applications where a verified pressure seal is critical, you must contact the manufacturer's custom design department. They can discuss your specific pressure requirements and arrange for appropriate testing or recommend a validated solution.
