3300/25

Overview

• Model: 3300/25
• Type: Dual Accelerometer Input Monitor
• Manufacturer: Bently Nevada

Inputs

• Signal: Accepts accelerometer inputs (two independent channels).
• Single Accelerometer Input: Can be used with a single transducer input, with both channels monitoring the same transducer using different signal processing.
• Signal Processing:
  • Channel A: Displays in acceleration units.
  • Channel B: Displays in velocity units.
  • Programmable filter configurations (high-pass, low-pass, band pass).

OK Function

• OK Status: Transducer output voltage within upper and lower OK limits.
• Timed OK/Channel Defeat:
  • Minimizes false alarms due to faulty wiring.
  • If the signal level is out of limits, the following occur:
    • OK LED off,
    • BYPASS LED on,
    • Channel disabled,
    • System OK Relay de-energizes.
  • Latching OK: Requires system reset for OK reset.

Alarm Functions

• Alarm Activation:
  • Alert: First-level alarm (press ALERT button).
  • Danger: Second-level alarm (press DANGER button).
• Setpoints: Displayed on front panel meter when activated.
• Relay Activation:
  • Corresponding relay contacts activated when preset signal levels are exceeded.
  • AND/OR Voting Logic: Determines when Danger relay contacts are activated.

Physical

• Operating Temperature: 0°C to +65°C (+32°F to +150°F).
• Storage Temperature: -40°C to +85°C (-40°F to +185°F).
• Weight: 1 kg (2.2 lbs.).
• Relative Humidity: Up to 95%, non-condensing.
