990-05-70-03-05 | Bently Nevada | 990 Vibration Transmitter
Designed for OEMs working with centrifugal air compressors, small pumps, motors, or fans, the 990 Vibration Transmitter provides a straightforward 4 to 20 mA proportional vibration signal for machinery control systems.
Key Features:
-
Input Compatibility:
- Accepts input from the 3300 NSv proximity probe and its matching extension cable (available in 5 m and 7 m system length options).
- Conditions the signal into appropriate peak-to-peak vibration amplitude engineering units.
-
Technical Specifications:
- Electrical Input Power: Requires +12 to +35 Vdc input at the transmitter terminal.
- 4 to 20 mA Signal Output: Provides a 4 to 20 mA signal output.
- 4 to 20 mA Loop Accuracy: Within ±1.5% over the specified full-scale range.
- Probe Gap: Probe must be gapped between 0.5 and 1.75 mm (20 and 55 mils) from target to ensure full-scale range.
- Maximum Loop Resistance: 1,000 Ω including cable at 35 Vdc.
- Current Limiting: 23 mA typical.
- Zero and Span: Adjustment for loop calibration.
- NOT OK/Signal Defeat: Circuit to prevent false alarms.
- Power-up Inhibit: Circuit to eliminate signal errors during power-up.
- Compatibility: Accepts 1 non-contacting 3300 NSv Proximity Probe and extension cable.
