Ordering Information for 990-05-50-02-00

Overview: The 990 Vibration Transmitter is a two-wire, loop-powered device designed to provide a simple 4 to 20 mA proportional vibration signal as input. This specific configuration, denoted by the code 990-05-50-02-00, is tailored to meet particular vibration monitoring requirements.

Specifications:

• Vibration Range:

  • Full-scale range of 0-5 mils pp (0-125 μm pp), ensuring precise vibration detection.

• System Length:

  • System length of 5.0 meters (16.4 feet), offering flexibility in installation.

• Mounting Option:

  • Bulkhead screws provided as the mounting option, ensuring secure installation.

• Agency Approval:
