The 16925-20 is a 35mm DIN rail mounting bracket/isolator specifically designed for Bently Nevada sensor systems (such as 330400 accelerometer interface modules or 3300 XL proximity probe proximitors). Its primary purpose is to securely fix the signal conditioning modules to standard industrial rails. Constructed from high-strength engineering plastic, it provides electrical isolation between the module case and the metal rail, effectively eliminating ground loop interference in the field.
Superior Electrical Isolation & Noise Reduction
Standardization & High Compatibility
Easy Snap-on Maintenance
The 16925-20 is a DIN rail mounting isolator designed for the 330400 and 330425 accelerometer interface modules. It provides secure physical support for these API 670-compliant sensors and ensures their precision 100 mV/g or 25 mV/g signals are free from ground loop interference through electrical isolation.

Petrochemical
Used for mounting vibration monitoring modules for ethylene units, extruders, and process pumps, providing essential electrical isolation.
Water & Wastewater
Secures vibration sensor modules for motors of large water supply pumps and wastewater treatment blowers.
Air Separation
Monitoring overspeed protection and vibration levels of large air separation compressors and turbo-expanders.
Pulp & Paper
Monitors signal transmission modules for high-frequency vibrations in paper machine drying sections and drive motors.
When using the 16925-20 mounting bracket, the focus must be on maintaining both physical stability and electrical isolation. It is essential to securely bolt the Proximitor to the bracket and ensure the plastic clips are firmly locked onto the 35mm DIN rail to prevent module loosening caused by industrial vibrations. To preserve critical ground isolation and eliminate interference, never use damaged or carbonized brackets. Additionally, during removal in extreme temperature environments, handle the spring clips with care to prevent the engineering plastic from cracking due to brittleness.
The 16925-20 is a rail mounting isolator/bracket specifically designed for Bently Nevada Proximitors.
What is the primary function of 16925-20?
Its core functions are physical support and electrical isolation.
How to install the 16925-20?
First, bolt the Proximitor onto the isolator bracket, then snap the entire assembly onto a standard 35mm DIN rail. It can be done without complex tools.
Which Proximitor models are compatible with 16925-20?
It is primarily compatible with 3300 XL series and earlier 3300 series Proximitors for 5-meter and 9-meter systems.
Does 16925-20 support use in hazardous areas?
Yes. As a passive mechanical component, it is typically certified with the Proximitor system under ATEX/IECEx for use in hazardous area control cabinets.
