Product Description

Overview

The Bently Nevada 133388-02 Internal Termination Block (ITB) is engineered for reliable connection between the 3500/42M Proximitor Seismic Monitor and its external sensors. Serving as the backbone for signal integrity, this block ensures that proximity probes, accelerometers, and velocity transducers deliver accurate vibration and position data for machinery protection systems. Unlike external termination blocks, the internal design mounts directly to the rack backplane, optimizing space and reducing potential connection errors.

Key Features

Precision Signal Transmission

• Low-noise design minimizes EMI/RFI interference, maintaining the accuracy of low-level vibration signals.

• High impedance matching prevents signal attenuation over long wiring runs.

Robust Connectivity

• Supports four independent channels corresponding to the 3500/42M monitor’s architecture.

• Secure screw or compression terminals provide vibration-resistant connections.

• Accommodates wire sizes from 0.2 mm² to 2.1 mm² (24 AWG to 14 AWG).

Durable Industrial Design

• Operating temperature: -30°C to +65°C (-22°F to +150°F).

• Resists humidity up to 95% non-condensing.

• Designed for harsh environments such as power generation plants and refineries.

System Compatibility

• Exclusively integrates with 3500/42M Proximitor Seismic Monitors.

• Compatible with 3300 XL Proximitor sensors, piezo-velocity transducers, and industrial accelerometers.

Technical Specifications

Applications

• Direct termination of Proximitor sensors, accelerometers, and velocity transducers.

• Reduces wiring complexity in 3500 racks by eliminating the need for external blocks.

• Ensures accurate signal delivery for machinery vibration monitoring and predictive maintenance.

FAQ

Q: Can the 133388-02 be used with external termination modules?
