Bently Nevada 1900/27 Vibration Monitor

Bently Nevada 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.

Product Overview

Type: Single channel, stand-alone, locally mounted vibration monitor.

Uses: Can be used as a stand-alone machinery protection device for general purpose machinery or certain critical machinery.

Interface: Provides a built-in 4-20 mA interface for trending of monitored parameters in plant control and automation systems.

Key features

Single-channel design: Supports a single sensor input, simplifying the installation and configuration process.

Stand-alone operation: The ability to work independently of other systems enhances system reliability and flexibility.

Local Display and Indication: Provides local display and status indication, which is convenient for users to monitor the vibration status in real time.

Alarm Function: Equipped with alarm relay contact outputs, which can be used to connect to external alarms for timely alarms.

System Integration: With the optional rack buffered output Transducer Interface Module (TIM), it can be used in conjunction with the Trendmaster 2000 system to achieve a wider range of machinery protection functions.

Technical specifications

Input: Accepts a single sensor input from a compatible Trendmaster® 2000 accelerometer, conditioning the signal to peak velocity units.

POWER SUPPLY: Supports AC voltages from 85 to 264 Vac and DC voltages from 110 to 370 Vdc with a frequency range of 47 Hz to 440 Hz, or DC.

LED Indicators:

OK: Normally illuminated green LED indicates normal status of the display, sensors, and field wiring. Flashing indicates that it was abnormal but has now recovered.

ALARM: The yellow LED indicates an alarm condition, flashing indicates that an alarm condition has occurred and disappeared (only if the alarm relay is configured as non-latching).

Hazard: one of the two red LEDs indicates a hazardous condition, blinking indicates that a hazardous condition has occurred and disappeared (only if the hazard relay is configured as non-latching).

Environmental Limits:

Operating temperature: -20°C to +70°C (-4°F to +158°F).

Storage temperature: -30°C to +90°C (-22°F to +194°F).

Relative humidity: to 95%, non-condensing.
