Quick Detail

Description

The 330909-10-99-10-11-CN 3300 NSv Proximity Probe is an eddy-current vibration probe used in automation monitoring of compressors, pumps, and small-shaft rotating machines. The 330909-10-99-10-11-CN 3300 NSv Proximity Probe features a 3/8-24 UNF threaded AISI 304 stainless steel case, PPS probe tip, and a 1.0 m FluidLoc cable with miniature coaxial ClickLoc connector. With a 1.5 mm linear range, recommended 1.0 mm gap, and 50 Ω output resistance, the 330909-10-99-10-11-CN 3300 NSv Proximity Probe measures shaft radial vibration, axial position, and keyphasor reference signals for DCS or PLC input channels.

Operating temperature is −52 °C to +177 °C, and supply sensitivity is below 2 mV/V, allowing the 330909-10-99-10-11-CN 3300 NSv Proximity Probe to transmit clear displacement signals to condition monitoring racks. The 9.9 in case length and 0.563 in thread engagement support installation in narrow machine housings where standard probes cannot fit. The 330909-10-99-10-11-CN 3300 NSv Proximity Probe is widely applied in centrifugal air compressors and process gas compressors requiring precise shaft position tracking.

Applications

Install 330909-10-99-10-11-CN 3300 NSv Proximity Probe on centrifugal compressor bearing housing
The 330909-10-99-10-11-CN 3300 NSv Proximity Probe uses a 1.5 mm linear range and 7.87 V/mm scale factor to send shaft radial vibration signals to a DCS rack. With a recommended 1.0 mm gap and 50 Ω output resistance, the probe directly feeds displacement data to vibration monitors for compressor load tracking.

Measure axial thrust position on process gas compressor rotor
Mounted facing the thrust collar, the 330909-10-99-10-11-CN 3300 NSv Proximity Probe detects axial movement and sends position voltage to PLC protection logic. The −52 °C to +177 °C operating temperature allows continuous measurement near hot process gas bearings.

Provide Keyphasor reference signal for turbine speed monitoring
Using the conductive keyway target, the 330909-10-99-10-11-CN 3300 NSv Proximity Probe outputs a phase reference pulse used by monitoring modules for shaft angle and overspeed calculation. The 1.0 m FluidLoc cable and ClickLoc connector support reliable connection to monitoring racks.

Monitor radial vibration on shafts smaller than 51 mm
Because the probe tip is PPS and the case uses 3/8-24 UNF threads, the 330909-10-99-10-11-CN 3300 NSv Proximity Probe fits narrow machine housings. The 9.9 in case length allows installation where standard 8 mm probes cannot enter.

Specifications

Competitive Advantage

Fit into restricted counterbore mounting holes
The 330909-10-99-10-11-CN 3300 NSv Proximity Probe has a slim probe body and 0.563 in maximum thread engagement. Maintenance crews can mount it inside tight bearing caps without machining large ports.

Transmit clear displacement voltage to monitoring modules
Supply sensitivity is less than 2 mV per volt change. The 330909-10-99-10-11-CN 3300 NSv Proximity Probe keeps the output signal accurate when cabinet power fluctuates, allowing monitors to read correct shaft position.

Maintain signal in high-temperature compressor area
The AISI 304 stainless steel case and PPS tip allow the 330909-10-99-10-11-CN 3300 NSv Proximity Probe to operate from −52 °C to +177 °C, so it can be installed near hot bearings and oil seals.

Secure cable connection during machine vibration
Gold-plated ClickLoc connectors and FluidLoc cable prevent loosening. The 330909-10-99-10-11-CN 3300 NSv Proximity Probe remains electrically connected during high vibration, avoiding signal loss to protection relays.

Connect directly to existing 3300 monitoring racks
The output scale factor of 7.87 V/mm allows the 330909-10-99-10-11-CN 3300 NSv Proximity Probe to feed standard Bently monitoring modules without recalibration, reducing installation work for maintenance engineers.
