Proximity Probe | APP1407030-00100 | Bently Nevada

Technical Specifications

The Bently Nevada APP1407030-00100 Proximity Probe is a non-contact vibration sensor that measures the displacement of a rotating shaft. It is used to monitor the condition of rotating machinery and to detect early signs of failure.

Features

Continuous Vibration Monitoring: Enables real-time assessment of machine health

Velocity Transducer: Measures vibration velocity, a key indicator of machine health

PeakVue Processing: Captures transient vibration events for improved fault detection

Rugged Construction: Built to withstand harsh industrial environments

Intrinsically Safe: Suitable for use in hazardous locations

Common Field Faults: Gap Voltage and DCS Trip Troubleshooting

Voltage between -2.0V and -18.0V: Indicates the probe's physical mounting gap is normal and the transmitter is fault-free. Please check the DCS analog input AI module calibration.

Voltage > -1.0V (close to 0V or even positive voltage): Usually indicates an insulation short circuit between the coaxial gold connector (ClickLoc) from the probe to the extension cable and the machine housing, or the probe is stuck on the shaft surface.

Voltage < -20.0V (or even close to the power supply limit): Indicates the probe's physical gap is too large (completely outside the 2mm linear measurement range), or the probe cable is broken or the core wire is disconnected.

Technical FAQ

Q: Where is APP1407030-00100 mainly used?

A: With 991 transmitters or 3500/42M modules to monitor radial vibration and shaft displacement in turbines, gears, and high-speed rotors.

Q: What are the linear range and sensitivity of APP1407030-00100?

A: Range: 0–2.0 mm (0–80 mils). Sensitivity: 200 mV/mil (≈7.87 V/mm), suitable for micrometer-level vibration detection.

Q: What is the advantage of NSv technology in APP1407030-00100?

A: The narrow tip reduces edge interference, allowing stable measurement in tight spaces, such as near shoulders, holes, or small shaft diameters.

Q: How is the electrical zero point set for APP1407030-00100 in the field?

A: Using a proximitor and non-contact gauge, adjust the gap until output is about -10.0 Vdc (midpoint of 2.0 mm range).
