Bently Nevada 135M1467-01 Ranger Pro Thermal Mounting Spacer

Product Description

The Bently Nevada 135M1467-01 is a precision-engineered mounting spacer designed for high-temperature applications within the Ranger Pro wireless sensor ecosystem. Acting as a thermal standoff, this component protects sensitive electronics and batteries from excessive heat while maintaining accurate vibration transmission.

Thermal Isolation for Hot Surfaces
By increasing the distance between the sensor and the machine surface, the 135M1467-01 allows standard Ranger Pro sensors (rated up to 85°C) to monitor equipment with surface temperatures up to 150°C or higher. Its stainless steel construction and optimized geometry ensure efficient heat dissipation while preserving mechanical integrity.

High-Fidelity Vibration Transmission
Unlike conventional insulators, this spacer is acoustically hard, allowing vibration signals up to 10 kHz to pass with minimal attenuation or phase distortion. The robust design prevents resonance and maintains accurate diagnostic data from the monitored machinery.

Durability and Environmental Resistance
Constructed from 316L stainless steel, the spacer withstands corrosive atmospheres, wash-down chemicals, and outdoor conditions. Precision threads (1/4-28 UNF standard) ensure a secure, metal-to-metal interface for both thermal and vibration transfer. Its low-profile design reduces the center of gravity, minimizing the risk of sensor detachment under high mechanical stress.

Applications
The 135M1467-01 is ideal for deploying Ranger Pro sensors on high-heat assets such as steam turbines, hot pumps, industrial ovens, and chemical reactors. It supports predictive maintenance by enabling accurate vibration and temperature monitoring in environments that would otherwise exceed sensor thermal limits.

Technical Specifications

Installation Tip

Apply a thin layer of silicone heat-sink compound or acoustic coupling grease to both ends of the spacer. This ensures optimal vibration transmission and efficient thermal management between the machine surface and the sensor.
