Ensure the proximity probe is gapped between 0.5 and 1.75 mm (20-55 mils) from the target surface to achieve full-scale range. The transmitter requires a +12 to +35 Vdc power supply at its terminals; verify polarity and loop resistance does not exceed 1,000 Ω at 35 Vdc. The leadwire from the Proximitor Sensor Output (BNC connector) should not exceed 3 metres (10 feet). Use shielded cable in noisy environments to maintain signal integrity.\u003c\/p\u003e\u003ch2\u003eTroubleshooting \u0026amp; Common Issues\u003c\/h2\u003e\u003cp\u003eCommon issues with vibration transmitters often stem from improper probe gap or power supply fluctuations. The Bently Nevada 990-05-50-01-01 includes a NOT OK\/signal defeat function that drives output below 3.6 mA within 100 µs if a fault occurs—such as probe damage or loss of power. This immediate reaction prevents controllers from acting on erroneous data. If the output remains at 4 mA or below, check the probe gap and verify the power supply is within +12 to +35 Vdc. The transmitter’s current limiting at 23 mA typical protects against loop shorts.
