Description of Vibration Transmitter
The 990 Vibration Transmitter is designed primarily for original equipment manufacturers (OEMs) of centrifugal air compressors or small pumps, motors, or fans who require a simple 4 to 20 mA proportional vibration signal as input to their machinery control system. The transmitter is a 2-wire, loop-powered device that accepts input from our 3300 NSv proximity probe and its matching extension cable (available in 5 m and 7 m system length options).
Specification of Vibration Transmitter
| Input | Accepts 1 non-contacting 3300 NSv Proximity Probe and extension cable |
|---|---|
| Power | Requires +12 to +35 Vdc input at the transmitter terminal |
| 4 to 20 mA Signal Output | 4 to 20 mAdc over specified full-scale range in 2-wire configuration |
| 4 to 20 mA Loop Accuracy | Within ±1.5% over specified full-scale range. Accuracy is rated from the TEST signal input to the voltage measured across a 250Ω loop resistance |
| 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 | 1,000Ω including cable at 35 Vdc |
| Current Limiting | 23 mA typical |
| Zero and Span | Non-interacting external adjustments |
| NOT OK/Signal Defeat | Signal output will go to less than 3.6 mA within 100 µs after a Not OK condition occurs. Signal output is restored within 2-3 seconds after the Not OK condition is removed |
| Power-up Inhibit | Signal output stays at less than 3.6 mA (NOT O.K.) for 2 to 3 seconds after power is applied. The purpose is to signal that the device is not yet ready. Transients may be observed when device goes O.K. |
| Proximitor Sensor Output | Compatible with ungrounded, portable test equipment. When using grounded, ac-powered test equipment, use the 122115-01 Test Adapter for signal isolation |
| Output Impedance | Prox Out has a 10 kΩ output impedance calibrated for a 10 MΩ load |
| Prox Out Linear Range | 1.4 mm (55 mils). Begins at approximately 0.25 mm (10 mils) from target surface |
| Prox Out Incremental Scale Factor | 7.87 mV/µm (200 mV/mil) ± 6.5% typical including interchangeability errors when measured in increments of 0.25 mm (10 mils) over the linear range using a flat 30 mm (1.2 inch) target. Worst case 7.87 mV/µm ± 10%. Typical Noise Level: 50 mV/pp |
| Temperature Stability | Incremental scale factor remains within ±10% of 7.87 mV/µm (200 mV/mil) from 0°C to +70°C (+32°F to +158°F) |
