Bently Nevada|1701/25| Seismic Input Monitor
Bently Nevada 1701/25-01 Seismic Input Monitor
Description
The Bently Nevada 1701/25-01 is a dual-channel seismic input monitor designed for measuring velocity and acceleration signals in industrial machinery protection systems.
Features
- Monitors direct, RMS, and integrated velocity and acceleration
- Compatible with multiple transducer types
- Supports programmable over-alert and danger alarms
- Includes embedded self-tests for system integrity
Technical Specifications
Measurement Capabilities
- Velocity Ranges (Peak): 0–0.5 to 0–3.0 in/s, 0–10 to 0–75 mm/s
- Integrated Velocity (pp): 0–5 to 0–500 µm, 0–5 to 0–20 mil
- Acceleration Ranges (Peak): 0–2 to 0–500 m/s², 0–2 to 0–50 g
- RMS Ranges: Same as peak ranges for velocity and acceleration
Signal Processing
- Velocity Bandwidth: Direct: 3 Hz – 5.5 kHz; RMS/Integrated: 10 Hz – 5.5 kHz
- Acceleration Bandwidth: Peak: 3 Hz – 31.55 kHz; RMS: 10 Hz – 31.55 kHz; Integrated: 20 Hz – 14.05 kHz
- Filters: High-pass: 3 Hz – 120 Hz; Low-pass: 100 Hz – 5.5 kHz
- Accuracy: 1% FS (>200 mVp), 2% FS (≤200 mVp)
Alarms
- Types: Over Alert, Danger on single proportional value
- Time Delays: 0.15 to 20 seconds
- Hysteresis: 0.5% of full-scale
Electrical
- Power Input: -24 V, +5 V, 1.5 W (no transducers)
- Buffered Output: 30 m max, 200 Ω impedance
- Resolution: Direct: 0.1%, Setpoint: 0.5% of full-scale
Physical and Environmental
- Dimensions: 127 x 21.6 x 105 mm (5 x 0.85 x 4.15 in)
- Weight: 314 g (0.69 lb)
- Operating Temp: -20°C to +70°C
- Storage Temp: -40°C to +85°C
- Humidity: 5% to 95% non-condensing
