Description

Overview

The Bently Nevada 330105‑02‑12‑15‑12‑05 reverse‑mount proximity probe is part of the 3300 XL 8 mm transducer family, engineered for applications where the probe must be installed from behind the mounting surface. This configuration is ideal for compact machinery designs or locations with limited frontal access. The probe delivers accurate eddy‑current displacement measurements for shaft vibration, position, and Keyphasor reference monitoring.

Key Characteristics

• Reverse‑mount 8 mm probe for confined or rear‑access installations

• Designed for use with 3300 XL Proximitor sensors

• Enhanced RFI/EMI immunity meeting CE requirements without shielded enclosures

• SpringLoc terminal technology for tool‑free wiring on associated Proximitor modules

• Suitable for small‑target and side‑view applications

• Standard 200 mV/mil (7.87 V/mm) scale factor

• Provides 1.5 mm (60 mils) linear range, exceeding legacy 3000‑series performance

Functional Description

The 330105‑02‑12‑15‑12‑05 probe is engineered for installations where traditional forward‑mount probes cannot be used due to space limitations or mechanical constraints. Its reverse‑mount design allows the sensing tip to be positioned accurately from behind the mounting surface while maintaining the same electrical characteristics as standard 3300 XL 8 mm probes.

When paired with a 3300 XL Proximitor sensor and extension cable, the probe provides precise monitoring of:

• Shaft radial vibration

• Axial position

• Thermal growth

• Keyphasor phase reference

• Speed measurement

The probe’s improved electromagnetic immunity ensures stable operation in electrically noisy environments. Its compact form factor and small‑target capability make it suitable for high‑density machinery layouts and OEM equipment designs.

Application Scenarios

• Compact machinery with limited frontal access

• Small motors, fans, and compressors

• Turbines and high‑speed rotating equipment

• OEM skid packages

• Installations requiring reverse‑mount probe geometry

FAQ
