Bently Nevada 1900/27-03 is a single-channel vibration monitor designed for condition monitoring of rotating machinery. Here’s what I could find on its technical specifications:

Function: It accepts a single transducer input from compatible 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.

Input:

• Transducer type: Eddy current proximity probe or piezoelectric accelerometer
• Input sensitivity: 100 mV/g

Output:

• Display: Local LCD display showing vibration level, alarm status, and other diagnostic information
• Analog output: 4-20 mA loop powered
• Relay outputs: Two programmable alarm relays

Features

• Scalable signal conditioning for various transducer types
• On-board diagnostics for sensor and system health
• User-configurable alarm levels and time delays
• Optional keypad for local configuration

Applications:

• Monitoring of pumps, fans, compressors, motors, and other rotating machinery
• Predictive maintenance programs
• Process protection
