Overview

The Bently Nevada 1900/27-01 is a single-channel, stand-alone vibration monitor designed for machinery protection. It accepts input from compatible Trendmaster® 2000 accelerometers, conditions the signal to peak velocity units, and provides local display, alarm relay outputs, and a 4-20 mA interface for integration with control systems.

Inputs

Compatible Transducers: Bently Nevada 200150 and 190520 Accelerometers
Input Sensitivity: 100 mV/g
Maximum Acceleration: 20 g peak
Maximum Differential Input Voltage: 4 volts peak-to-peak

Power

AC/HDC Power Version

Voltage: 85 to 264 Vac / 110 to 370 Vdc
Current Draw: 60 mA (typical), 120 mA (maximum)
Frequency: 47 Hz to 440 Hz or DC
Inrush Current: 20A (typical) @ 100Vac, 40A (typical) @ 200Vac

+24 Vdc Power Version

Voltage: 18 to 36 Vdc
Current Draw: 300 mA (maximum)

Signal Conditioning

Monitor Full-Scale (Below 614 Hz)
- English Units: 2.0 in/s (zero-to-peak)
- Metric Units: 50.8 mm/s (zero-to-peak)
- Note: Full scale is limited by maximum input above 614 Hz. Max input is 2 volts peak or 20 g peak. At 614 Hz, 20 g equals 2 in/s, the full-scale range of the monitor.
- Above 614 Hz: Full scale is calculated as (1228 / frequency).
Frequency Response
- High-Pass Corner: -3 dB @ 8 Hz, <1% error due to high-pass corner above 30 Hz
- Low-Pass Corner: >4 kHz, <1% error below 4 kHz
Accuracy
- Liquid Crystal Display and Buffered Output
  - 30 Hz – 4 kHz: ±3% of full scale
  - 8 Hz – 30 Hz: -30%, +3% of full scale
- 4-20 mA Recorder Output
  - 30 Hz – 4 kHz: ±5% of full scale
  - 8 Hz – 30 Hz: -30%, +5% of full scale

Outputs

Buffered Transducer Output

Output Sensitivity: 19.7 mV/mm/s (500 mV/in/s)
Output Impedance: 500 Ω
Full-Scale Range: 50.8 mm/s (2 in/s) zero-to-peak

4-20 mA Output

Full-Scale Range: 20 mA @ 50.8 mm/s (2 in/s)
Overrange: 63.5 mm/s (2.5 in/s)
Accuracy: Adjustable with trimpot
Galvanic Isolation: Optical @ 1000 Vac or 707 Vdc
