Quick Detail

Description

The 330907-05-30-10-02-00 3300 NSv Reverse Mount Probe is a high-precision eddy-current proximity transducer designed for industrial automation systems requiring compact installation. Engineered for use in centrifugal air compressors, refrigeration compressors, and process gas compressors, the 3300 NSv probe excels in environments with limited side-view, counter bore, or rear-view space. Featuring a total length of 1.0 meter (39 in) and a 3/8-24 UNF threaded probe case, this probe supports tight integration in small machinery while maintaining reliable linear measurement. The probe tip is constructed from polyphenylene sulfide (PPS) for high chemical resistance, and the probe body is made from AISI 304 stainless steel (SST), ensuring durability under extreme conditions. It operates across a temperature range of -52°C to +177°C (-62°F to +351°F) and supports field wiring of 0.2–1.5 mm², making it versatile for various industrial applications. The probe offers a linear range of 1.5 mm (60 mils) and a recommended gap setting of 1.0 mm (40 mils), delivering accurate radial vibration, axial position, and phase reference measurements in compact installations. The 3300 NSv probe system is fully compatible with Bently Nevada’s 3300 RAM and 3000/7000-series transducer systems, allowing seamless upgrades while maintaining high performance.

Applications

1. Radial Vibration Monitoring on Small Shafts
Designed for shafts smaller than 51 mm (2 in), the 3300 NSv reverse mount probe accurately detects radial vibration in centrifugal compressors and other rotating machinery. Its 1.5 mm linear range ensures precise monitoring even in high-speed applications.

2. Axial (Thrust) Position Measurement
Ideal for flat targets smaller than 15 mm (0.6 in), the probe measures axial shaft movement in fluid-film bearing machines, providing reliable feedback for process control and protection.

3. Tachometer and Zero-Speed Detection
With a 50 Ω output resistance and high supply voltage sensitivity (<2 mV per volt change), the probe provides precise speed and zero-speed measurements for automation systems requiring exact rotational data.

4. Phase Reference (Keyphasor Signals)
The probe delivers accurate Keyphasor signals for rotor phase reference in critical rotating equipment, enabling synchronization with control and protection systems.

5. Small Target Process Applications
Thanks to its chemically resistant PPS tip and SST body, the probe operates in harsh environments such as refrigeration or process gas compressors, maintaining accuracy in challenging chemical and temperature conditions.

Specifications

Competitive Advantage

1. Compact Reverse-Mount Design
The 3300 NSv probe allows installation in restricted counter bore and side-view areas, solving spatial constraints that standard 3300 XL probes cannot address.

2. Enhanced Chemical Resistance
The PPS probe tip and stainless-steel housing resist corrosive process fluids, extending probe life compared to traditional 3300 RAM probes.

3. High Mechanical and Electrical Compatibility
Fully compatible with 3300 RAM extension cables and Proximitor sensors, facilitating cost-effective upgrades without replacing the monitoring system.

4. Superior Connection Reliability
Equipped with gold-plated ClickLoc connectors and patented TipLoc molding, ensuring robust electrical and mechanical connection, supporting connector torque up to 22.6 N•m (200 in•lb).

5. Optimized Linear Range for Small Targets
With a 1.5 mm (60 mils) linear range and precise recommended gap of 1.0 mm, the probe achieves highly accurate measurements on small diameter shafts and flat targets, outperforming legacy 3000-series transducers.
