BENTLY 1900/27 Vibration Monitor

BENTLY 1900/27 Vibration Monitor

Description

The 1900/27 is a single-channel, stand-alone, locally mounted vibration monitor. It can be used as a stand-alone machinery protection device, suitable for general-purpose or some essential machinery and provides a built-in 4-20 mA interface for trending the monitored parameter in plant control and automation systems. The 1900/27 accepts a single transducer input from compatible Trendmaster® 2000 accelerometers, conditions the signal into peak velocity units, and provides local display and status indication as well as alarm relay contact outputs for connection to an external annunciator.

By using an optional Rack Buffered Output Transducer Interface Module (TIM), the 1900/27 can also be used in conjunction with our Trendmaster 2000 system. It allows the user to apply machinery protection capabilities to all (or selected) seismic vibration points of the Trendmaster 2000 system.
