Bently Nevada|3300/45-02-02-03-00|Dual Differential Expansion Monitor

Description

Features

• Monitors two differential expansion channels (Channel B configurable to OFF for single-location use).
• Four alarm setpoints per channel (two over/under) with adjustable thresholds and First Out indication.
• User-programmable analog outputs, buffered transducer signals, and real-time status via LCD/LED displays.
• Field-adjustable options for measurement range, relay types, and alarm response logic.

Technical Specifications

• Two proximity probe signals for axial displacement measurement.
• Input impedance: 10 kΩ per channel.
• Signal scale factor: 20 mV/mil (0.787 V/mm) or 10 mV/mil (0.392 V/mm) (jumper-selectable).

• Accuracy: ±0.33% typical, ±1% maximum (25°C).
• Power consumption: 1.5 W.

• Recorder outputs (per channel):
  • +4–20 mA (±0.7% signal, ±0.09 mA offset),
  • +1–5 Vdc (±1.1% signal, ±10 mV offset),
  • 0–10 Vdc (±1.1% signal, ±15 mV offset).
• Output impedance (voltage): 100 Ω (min. load 10 kΩ); current compliance: 0–12 Vdc (0–600 Ω load for 4–20 mA).
• Buffered transducer outputs: Front-panel coaxial connectors and rear-panel terminals, short-circuit protected (100 Ω impedance), -24 Vdc supply.

• Alarm setpoints: 0–100% full-scale, resolution ±1.6%, repeatability ±0.4%.
• LCD: 63-segment vertical bargraph per channel (83 mm height), showing probe gap, error codes, and adjustment mode.
• LEDs: Green OK indicators (per channel), red Alarm (Alert/Danger with First Out flashing), red Bypass status.

• Operating temp: 0–65°C; storage temp: -40–85°C.
• Humidity: Up to 95% non-condensing.
• Weight: 1 kg (2.2 lbs); rack mount: single position (excludes slots 1–2 for power/system monitor).
