Product Description

Overview

The Bently Nevada Ranger Pro 134M2166-01 serves as the robust housing and power module for Ranger Pro wireless condition monitoring sensors. Engineered for high-precision vibration data acquisition, this assembly houses the D-cell Lithium Thionyl Chloride battery and provides a secure mounting interface, enabling reliable operation in demanding industrial and offshore environments. Its modular construction allows for field replacement, preserving the internal accelerometer and radio module.

Key Technical Features

Material and Construction

• Primary body: 316L Stainless Steel for corrosion resistance and mechanical stability

• Top cap: High-performance Polyphenylene Sulfide (PPS) for electrostatic dissipation

• Sealing: IP67 rated with precision O-rings to resist dust and water ingress

Mechanical and Vibration Performance

• High-rigidity base for accurate vibration transfer to internal piezoelectric sensors

• Frequency support up to 10 kHz on the Z-axis for early bearing fault detection

• Mounting threads: 1/4-28 UNF or M6x1 for secure machine attachment

Power and Maintenance

• Supports replaceable 3.6V Lithium Thionyl Chloride D-cell batteries

• Field-serviceable design allows replacement of housing, threads, or battery contacts without disassembling the sensor core
