This industrial automation module accepts one non-contacting 3300 NSv Proximity Probe and extension cable, converting vibration signals into a standard 4 to 20 mA output. Designed for continuous monitoring, the Bently Nevada 990-08-70-03-CN ensures early fault detection and reduced downtime.\u003c\/p\u003e\u003ch2\u003eKey Technical Specifications\u003c\/h2\u003e\u003cp\u003eThe Bently Nevada 990-08-70-03-CN 990 Vibration Transmitter provides precise measurements with the following parameters:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull-Scale Range:\u003c\/strong\u003e 0-8 mils pp (0-200 μm pp)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-20 mA Loop Accuracy:\u003c\/strong\u003e Within ±1.5% over full-scale range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 5 Hz to 6,000 Hz (+0, 3 dB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e +12 to +35 Vdc input\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Loop Resistance:\u003c\/strong\u003e 1,000 Ω at 35 Vdc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Limiting:\u003c\/strong\u003e 23 mA typical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Length Option:\u003c\/strong\u003e 7.0 meters (23.0 feet)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Option:\u003c\/strong\u003e DIN clips and screws\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIndustrial Applications\u003c\/h2\u003e\u003cp\u003eThe Bently Nevada 990-08-70-03-CN 990 Vibration Transmitter is ideal for monitoring vibration in turbines, compressors, pumps, and fans. With a minimum target size of 9.5 mm (0.375 in) diameter and probe gap requirements of 0.5 to 1.75 mm, it reliably measures shaft displacement. Its NOT OK\/signal defeat feature ensures rapid detection of faults, making it suitable for critical machinery protection loops.\u003c\/p\u003e\u003ch2\u003eInstallation and Setup Guide\u003c\/h2\u003e\u003cp\u003eMount the Bently Nevada 990-08-70-03-CN using DIN clips or screws. Connect a 3300 NSv Proximity Probe and extension cable; leadwire length from the Proximitor Sensor Output (BNC connector) must not exceed 3.0 meters (10 feet). Ensure the probe gap is between 0.5 and 1.75 mm from the target. Power the transmitter with +12 to +35 Vdc at the terminal. Adjust zero and span using the non-interacting external controls.\u003c\/p\u003e\u003ch2\u003eTroubleshooting and Common Issues\u003c\/h2\u003e\u003cp\u003eThe Bently Nevada 990-08-70-03-CN includes a signal defeat mechanism that forces output below 3.6 mA within 100 µs after a Not OK condition, restoring within 2-3 seconds after removal. Verify loop resistance does not exceed 1,000 Ω at 35 Vdc. If output is inaccurate, check probe gap and supply voltage.
