Description

Option 00 (0.0 in unthreaded length) and Option 09 (0.9 in overall case length) specify the physical envelope of this 330901-00-09-70-02-05 3300 NSv proximity probe, which is calibrated for non-contact eddy-current displacement measurements on small-diameter shafts and in tight spaces. It provides radial vibration and axial position feedback under severe industrial conditions.

In contrast to armored variants such as the 330902 model, this non-armored 1/4-28 UNF-2A standard mount probe is intended for installations within machinery where external cable routing does not require mechanical protection conduit. It operates in conjunction with the 330980 Proximitor Sensor and 330930 Extension Cable as a matched system with a total length of 7.0 meters.

Features

Threaded 1/4-28 UNF-2A steel probe case without protective armor
Zero unthreaded length (0.0 in) for maximized thread engagement in thin-walled casings
0.9-inch overall case length suitable for tight clearance envelopes
7.0-meter integrated standard cable with ClickLoc miniature coaxial connector
Multiple international agency approvals (Option 05) for hazardous locations

Applications

Shaft vibration and axial position monitoring on small-bore machinery
Rotor dynamics measurements on high-speed equipment with limited target geometry
Displacement monitoring in aeroderivative turbines and industrial gearboxes
Tight clearance non-contact sensing where space constraints restrict larger probes

Installation Guidelines

Standard mount 1/4-28 UNF thread probes are supplied with a 7/16-inch lock nut and 7/32-inch wrench flats. Ensure that the mounting bracket is rigid to avoid false vibration readings, and check that the probe-to-extension-cable connector is insulated using silicone tape or connector protectors to prevent oil and moisture intrusion. Sustained exposure of the Viton seal to temperatures below -34 degC (-30 degF) may compromise the pressure barrier.

FAQ

What is the significance of the unthreaded length (Option 00) on this probe?

Option 00 specifies a 0.0-inch unthreaded length, meaning the probe body is fully threaded. This maximizes thread engagement and is ideal for mounting in thin-walled machine casings where maximum stability is required.

What are the target shaft diameter requirements for the 3300 NSv system?

The 3300 NSv system is designed for small target geometries. Radial vibration or position measurements on shafts smaller than 20 mm (0.8 inches) will typically result in less than a 10% change in Average Scale Factor (ASF).

Which cables and Proximitor sensors are compatible with this probe?

This probe must be paired with a 3300 NSv Extension Cable (such as 330930) and a 3300 XL NSv Proximitor Sensor (such as 330980). The total length of the probe and extension cable combined must match the Proximitor Sensor system length (7.0 meters).

What does Option 05 represent for the agency approval parameter?

Option 05 designates multiple international agency approvals, including ATEX, IECEx, and CSA certifications for intrinsically safe and non-incendive installations in hazardous locations.
