BENTLY 1900/27

Description

describe

1900/27 is a single-channel, independent, locally installed vibration monitor.

It can be used as an independent mechanical protection device for

General or some basic machinery, and provide built-in 4-20 mA

Interface for monitoring parameter trends in plant control and automation

System. 1900/27 accepts a single sensor input from a compatible device

Trendmaster ® 2000 accelerometer, adjust signal to peak speed

And provide local display and status indication as well as alarm relay

Contact output for connecting to external alarm.

By using the optional Rack Buffered Output Sensor Interface Module (TIM),

1900/27 can also be used with our Trendmaster 2000 system.

It allows the user to apply the mechanical protection function to all (or selected)

Seismic vibration point of Trendmaster 2000 system.

Note: If your application requires connection to Bently Nevada’s Trendmaster 2000 system, but

Do not need 4-20 mA interface with other systems, please consider using our 1900/25 monitor
