Description

330901-11-25-10-01-00: 3300 NSv proximity probe with 1/4-28 UNF threads and no armor, configured with 1.1 in of unthreaded length, a 2.5 in case length, a 1.0 m (39 in) total length, a standard cable with a miniature coaxial ClickLoc connector and connector protector, and no agency approvals.

This probe configuration differs from sibling models by incorporating a 1.1 in unthreaded section alongside a 2.5 in case length, providing specific clearance dimensions suited for small-bore machinery. Unlike variants with stainless steel armor (such as the 330902) or those featuring FluidLoc cables for oil sealing, this unarmored standard cable version with an integrated fluorosilicone connector protector is suited for clean environments requiring tight spatial clearance.

Features

Option 11 specifies a 1.1 in (27.9 mm) unthreaded probe body length.
Option 25 specifies a 2.5 in (63.5 mm) overall threaded case length with 1/4-28 UNF threads.
Option 10 provides a total electrical length of 1.0 m (39 in) of FEP-insulated coaxial cable.
Option 01 supplies a gold-plated brass ClickLoc coaxial connector with an integrated fluorosilicone connector protector.
Option 00 specifies that hazardous area approvals are not required.
Miniature coaxial cable structure with standard 75 ohm characteristic impedance.
Unarmored mechanical design for compact, direct-threaded installations.

Applications

Small-bore machinery vibration monitoring
Shaft vibration and axial position measurement in aeroderivative gas turbines
Fluid film bearing clearance and shaft position sensing
High-speed equipment with limited target geometry and restricted installation clearances
Process compressor shaft displacement monitoring

Installation Guidelines

Securely mount the 1/4-28 probe case using a standard recommended torque of 5.1 Nm (45 in-lb); do not exceed the maximum rated limit of 7.3 Nm (65 in-lb).
Ensure the minimum bend radius of the coaxial cable does not fall below 25.4 mm (1.0 in) during routing.
Install the integrated fluorosilicone connector protector over the ClickLoc mating interface to prevent liquid contaminants from altering electrical signals.
Maintain at least 25 mm (1.0 in) separation distance between transducer tips for axial measurements, and 23 mm (0.9 in) for radial vibration measurements to eliminate cross-talk interference.

FAQ

What do the Option 11 and Option 25 values specify for this 330901 probe?

Option 11 specifies an unthreaded length of 1.1 inches, while Option 25 specifies an overall case length of 2.5 inches. This configuration provides specific insertion clearance dimensions designed for small-bore machinery installations.

Does the 330901-11-25-10-01-00 probe include stainless steel armor?

No, this specific configuration is unarmored (without armor). It features a standard 75 ohm coaxial cable protected by a fluoroethylene propylene (FEP) outer jacket.

What is the function of the connector and cable option 01 on this unit?

Option 01 designates a miniature coaxial ClickLoc connector with an integrated fluorosilicone connector protector. This protective sleeve seals the physical connection between the probe lead and extension cable against oil and moisture ingress.

What are the agency approvals for this specific SKU?

This probe is ordered under Option 00, meaning hazardous area safety approvals are not required or supplied with this physical unit. However, it still complies with general industrial standard CE, RoHS, and China RoHS directives.
