Specification of BENTLY NEVADA 991-25-XX-01-CN
Item | Specidication |
| Manufacuturer | Bently Nevada |
| Product No. | 991-25-XX-01-CN |
| Product Type | 991 Thrust 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 (typical). Accuracy is rated from the TEST signal input to the voltage measured across a 250 Ω loop resistance. |
| Maximum Loop Resistance | 1,000 Ω 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 0.1 seconds after the Not OK condition is removed. |
| 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. |
| Linear Range | 0.25 to 1.65 mm (10 to 65 mils) for Prox Out. Suitable for 0.60-0.6 mm or 25-0-25 mils current loop linear ranges. |
