Its 5 Hz to 6 kHz frequency response covers both low-speed rotor dynamics and high-speed gear mesh frequencies. The ±1.5% loop accuracy ensures reliable data for predictive maintenance programs, reducing unplanned downtime and extending equipment life.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eMount the transmitter on a standard 35 mm DIN rail using the provided clips. Connect the 3300 NSv Proximity Probe to the BNC input, ensuring cable length does not exceed 3 meters. Gap the probe between 0.5 and 1.75 mm (20 to 55 mils) from the target to achieve full-scale range. Power the transmitter with +12 to +35 Vdc at the terminal; the loop resistance must not exceed 1,000 Ω at 35 Vdc. Non-interacting external adjustments for zero and span simplify calibration.\u003c\/p\u003e\u003ch2\u003eCompatibility \u0026amp; Integration\u003c\/h2\u003e\u003cp\u003eDesigned for use with Bently Nevada 3300 NSv Proximity Probes, the 990-10-70-01-CN outputs a standard 4-20 mA signal compatible with most PLCs, DCS, and SCADA systems. The signal defeat feature drops output below 3.6 mA within 100 µs upon a Not OK condition, ensuring fail-safe operation. The transmitter is suitable for Non-Hazardous, Zone 2, or Division 2 hazardous area locations when paired with a 28 V power supply.\u003c\/p\u003e\u003ch2\u003eBuying Guide \u0026amp; Selection Advice\u003c\/h2\u003e\u003cp\u003eBefore purchasing, verify that your existing probe model is a 3300 NSv with compatible extension cable. Confirm loop resistance requirements and power supply voltage range (+12 to +35 Vdc).
