Bently 1900/65A General Purpose Equipment Monitor

The Bently 1900/65A serves as a robust mechanical protection solution for industrial machinery where continuous condition monitoring is required without the complexity of full-scale turbine protection systems. Designed for auxiliary equipment like pumps, compressors, and generators, this unit combines flexibility with industrial-grade durability. Its eight-channel configuration (4 vibration + 4 temperature) allows simultaneous monitoring of multiple parameters, making it particularly valuable for facilities needing cost-effective protection for non-critical assets.

This unit shines in applications where basic protection is needed without integrating into larger Bently systems. A power plant maintenance manager recently shared how they use it for monitoring feedwater pumps – “It’s perfect for secondary equipment where we need vibration alerts but don’t want to invest in full 3500 system architecture.” The modular design allows easy integration with existing DCS systems through its 4-20mA outputs, while the Ethernet interface enables remote configuration via Bently’s System 1 software.

We maintain active stock of 1900/65A units and complementary 1900 series components including 1900/27 vibration sensors and 1900/28 temperature modules. Our inventory also includes related Bently hardware like 3500 rack components (3500/22M, 3500/42M) and 3300 system monitors for complete solution provisioning.
