FAQ:

Q1: What is the primary use of the Bently Nevada 990 Vibration Transmitter?
A1: The 990 Vibration Transmitter is mainly used for OEMs of centrifugal air compressors, small pumps, motors, or fans. It provides a 4 to 20 mA proportional vibration signal for machinery control systems.

Q2: How does the Bently Nevada 990 work?
A2: The transmitter accepts input from a 3300 NSv proximity probe, processes the vibration signal, and outputs it as a 4 to 20 mA proportional signal for monitoring and control systems.

Q3: What is the maximum loop resistance for the 990 Vibration Transmitter?
A3: The maximum loop resistance is 1,000 Ω, including the cable, at 35 Vdc.

Q4: What temperature range can the 990 Vibration Transmitter operate in?
A4: The operating temperature range is from -35°C to +85°C (-31°F to +185°F).

Q5: Can the 990 Vibration Transmitter be used in hazardous environments?
A5: Yes, it complies with various certifications, including ATEX Zone 2 and Class I, Div 2 for hazardous locations.

Q6: What is the typical signal output of the 990 Vibration Transmitter?
A6: It outputs a 4 to 20 mA signal over the specified full-scale range for use in machinery control systems.

Q7: What is the probe gap required for accurate operation?
A7: The probe gap must be between 0.5 mm and 1.75 mm (20 to 55 mils) from the target to ensure full-scale range accuracy.

Q8: How does the 990 handle faulty probes?
A8: The “Not OK/Signal Defeat” circuit ensures that the signal output goes to less than 3.6 mA within 100 µs after a fault occurs, preventing false alarms.
