Application Context
This module excels in monitoring critical machinery like steam turbines, centrifugal compressors, and large motor-driven equipment. A refinery in Texas recently implemented this module to address recurring bearing issues in their gas processing turbines – the real-time vibration data enabled predictive maintenance that reduced unplanned downtime by 60%.
We regularly supply this module alongside related BENTLY components including the 3500/42M relay module, 3500/15 power supply, and 3500/20 proximitor. Our inventory also includes compatible 3300 series components for legacy system integration.
Our Value Proposition
With 16 regional warehouses across 6 countries, we typically deliver BENTLY modules within 5-7 business days. All our used components undergo 48-hour functional testing, and we offer a full 12-month warranty covering both parts and labor.
