190027 BENTLY
Vibration monitor
The 1900/27 is a single channel, independent, locally installed vibration monitor. It can be used as an independent mechanical protection device, suitable for general or some important machinery, and provides a built-in 4-20 mA interface for monitoring parameter trends in plant control and automation systems. 1900/27 accepts from compatible Trendmaster ® The single sensor input of the 2000 accelerometer adjusts the signal to peak speed units and provides local display and status indication as well as alarm relay contact outputs for connection to external annunciators.
