Technical Support Questions

What are the advantages of UNC coarse thread mounting?

UNC threads provide faster installation and are less prone to cross-threading, making them ideal for field applications and maintenance.

How does the enveloping technology enhance bearing fault detection?

It amplifies high-frequency bearing defect signatures while filtering out lower frequency vibrations, enabling early detection of bearing wear.

What industries commonly use this accelerometer model?

Manufacturing plants, power generation facilities, and industrial sites requiring reliable bearing monitoring and cavitation detection.

How does the ceramic shear sensing technology improve performance?

It provides excellent temperature stability and maintains accuracy across the entire operating range in harsh industrial environments.

What is the significance of the fast 300ms settling time?

It ensures quick system response and enables rapid detection of dynamic machinery conditions and potential faults.
