Description

Option 00 (0.0 in unthreaded length), Option 25 (2.5 in overall case length), and integral stainless steel armor specify this 3300 XL 11 mm proximity probe configuration — 330702-00-25-10-02-05. This eddy-current non-contacting displacement probe features a 1/2-20 UNF threaded case with a protective AISI 302 stainless steel armor sleeve and FEP outer jacket over a 1.0-meter (3.3 feet) standard coaxial cable. It is configured with a miniature coaxial ClickLoc connector and is certified for multiple hazardous area approvals. Unlike non-armored variations such as the 330701, the armored 330702 model provides mechanical protection against debris, abrasion, and physical impact in demanding rotating machinery environments. The large 11 mm tip delivers an extended linear range of 4.0 mm (160 mils), enabling accurate axial (thrust) position, ramp differential expansion, and reciprocating compressor rod drop monitoring when paired with a compatible 330780 Proximitor sensor and 330730 extension cable.

Features

Base model 330702 provides an integrated AISI 302 stainless steel armor sleeve with an FEP outer jacket for enhanced mechanical durability.
Option 00 specifies a 0.0-inch unthreaded length, allowing full case threading for deep engagement or precise mounting positioning.
Option 25 establishes a 2.5-inch overall case length with 1/2-20 UNF-2A threads.
Option 10 specifies a 1.0-meter (3.3 feet) total cable length, requiring a matching extension cable to reach system length configurations.
Option 02 provides a gold-plated miniature ClickLoc coaxial connector for low-resistance, secure interlocking connections.
Option 05 grants multiple hazardous area approvals, enabling installation under international intrinsic safety (ia) and non-sparking (nA/ec) regulatory standards.

Applications

Turbine and compressor shaft vibration measurements.
Axial (thrust) position measurements on fluid film bearing machines.
Ramp differential expansion measurements on steam turbines.
Rod position or rod drop measurements on reciprocating compressors.
Tachometer, zero speed, and Keyphasor phase reference signal generation.

Installation Guidelines

Maintain a minimum bend radius of 25.4 mm (1.0 in) for both armored and non-armored cables to prevent signal loss or physical breakage.
Install probes using the recommended mounting torque of 15.2 N-m (133 in-lb) to prevent damage to the 1/2-20 threaded case. Do not exceed 45.2 N-m (400 in-lb).
Ensure connector-to-connector interfaces are finger-tight. The maximum allowable torque is 0.565 N-m (5 in-lb).
Maintain a proper probe gap, typically 2.5 mm (100 mils) for center-of-range operation within the 4.0 mm (160 mils) linear band.

Compliance and Certifications

Option 05 Multiple Approvals package covers CSA, ATEX, IECEx, and NEPSI certifications for hazardous areas.
Intrinsically Safe (ia) compliance when installed with approved zener barriers or galvanic isolators.
Non-sparking / non-incendive (nA, ec) zone classifications compatible.
Conforms to CE standards, RoHS directive 2011/65/EU, and China RoHS.
Functional Safety: SIL 2 (HFT = 0) and SIL 3 (HFT = 1) compatible.

What is the difference between the Bently Nevada 330702 and 330701 proximity probes?

The 330702 base model is manufactured with integrated stainless steel armor over the cable for physical protection, whereas the 330701 model has a standard FEP-insulated coaxial cable without armor.

What are the specific unthreaded and case lengths for SKU 330702-00-25-10-02-05?

This probe configuration features a 0.0-inch unthreaded length (Option 00), meaning the body is fully threaded, and a 2.5-inch overall case length (Option 25) with a 1/2-20 UNF-2A thread.

What extension cable is compatible with this 1.0-meter proximity probe?

This probe has a total length of 1.0 meter (Option 10). To achieve a standard 5.0-meter system length, it must be paired with a 4.0-meter 330730 extension cable. For a 9.0-meter system, pair it with an 8.0-meter extension cable.

Does Option 05 on this probe include hazardous area approvals?

Yes, Option 05 designates Multiple Approvals, which covers major international certifications such as CSA, ATEX, IECEx, and NEPSI for intrinsic safety and non-sparking environments.
