• Mounting: It includes 35 mm DIN rail clips for quick and secure panel mounting.
• Probe Setup: The probe must be gapped 0.5 to 1.75 mm (20-55 mils) from the target shaft.
• Minimum Target: The target must have a minimum diameter of 9.5 mm (0.375 inches).
• Fault Indication: A "NOT OK" condition drives the output below 3.6 mA within 100 microseconds.

Frequently Asked Questions (FAQ)

• Q: What is the main application of this Bently Nevada transmitter?
  A: The Bently Nevada 990-10-50-01-00 is designed for OEMs to provide a simple 4-20 mA vibration signal to PLCs or control systems for basic machinery protection.
• Q: Does this model have certifications for hazardous areas?
  A: No, the "00" option in the model number means it has no hazardous area agency approvals. It is for use in standard industrial, non-hazardous locations.
• Q: Can I use a different length of cable with this transmitter?
  A: The "50" option means it is calibrated for a 5.0-meter system. Using a different cable length may affect the accuracy of the vibration measurement.
• Q: How do I get a diagnostic signal from this device?
  A: The transmitter has a BNC "PROX OUT" connector. For safe connection to test equipment, Bently Nevada strongly recommends using their 990/991 Test Adapter for isolation.
• Q: What does the Not OK/Signal Defeat feature do?
  A: If the probe fails or disconnects, this feature forces the 4-20 mA output below 3.6 mA within 100 µs. This provides a clear fault signal to your control system to prevent false alarms.
