Bently Nevada 113819-01 Proximitor Sensor Extension Cable

Description

Key Technical Specifications

Verification note: Public distributor information is inconsistent. One listing identifies 113819-01 as a matched Bently Nevada extension cable, while another incorrectly categorizes it as a vibration transmitter/sensor assembly and provides specifications such as 4–20 mA output. Those conflicting specifications should not be used for procurement without OEM documentation or a nameplate check.

Product Introduction

The Bently Nevada 113819-01 is identified by available industrial-part listings as a dedicated extension cable for an eddy-current vibration measurement loop. It connects the vibration probe assembly with the associated proximitor or monitoring electronics and maintains the required signal characteristics.

This is not a generic instrumentation cable. The cable’s electrical characteristics, connector configuration, and physical length matter when replacing it. For turbine, compressor, generator, and other rotating-equipment monitoring systems, verify the complete probe–extension cable–proximitor combination before installation.

Installation & Configuration Guide

Stage 1: Pre-Installation Preparation — 10 minutes

1. ⚠️ Place the monitored machine in the required safe state before disconnecting the vibration monitoring circuit.
2. Follow the site’s electrical isolation and lockout/tagout procedure.
3. Prepare an ESD strap, multimeter, cable labels, camera, and appropriate hand tools.
4. Photograph both ends of the existing 113819-01 installation.
5. Record the probe part number, proximitor part number, cable length, connector style, and routing.
6. Do not cut the existing cable before the replacement has been positively identified.

Stage 2: Removing the Existing Cable — 5–10 minutes

1. Confirm that the associated monitoring circuit is safely isolated.
2. Label both cable ends.
3. Disconnect the cable from the proximitor/electronics end.
4. Disconnect the cable from the vibration probe end.
5. Remove the cable from its existing routing.
6. Inspect connectors for corrosion, bent contacts, contamination, or mechanical damage.
7. Compare the removed cable directly against the replacement.

⚠️ Do not substitute ordinary coaxial or instrumentation cable simply because the connector appears compatible. Available technical listings specifically describe 113819-01 as a matched cable for the Bently Nevada eddy-current measurement loop.

Stage 3: Installing the Replacement — 5–10 minutes

1. Verify the part number: 113819-01.
2. Confirm the connector arrangement against the original cable.
3. Route the replacement along the original path where practical.
4. Maintain the manufacturer’s required bending radius.
5. Keep the signal cable separated from high-current and high-frequency power conductors.
6. Connect both ends without forcing the connectors.
7. Secure the cable against vibration and abrasion.
8. Check that the cable does not contact rotating or hot machinery.

Self-Checklist:

• Part number verified
• Probe compatibility verified
• Proximitor compatibility verified
• Connector type matches
• Cable routing checked
• No sharp bends or mechanical strain
• Connectors fully secured

Stage 4: Power-On & Functional Testing — 10–15 minutes

1. Inspect the complete measurement loop before energizing.
2. Restore power to the associated monitoring equipment.
3. Check for normal proximitor/monitor status.
4. Confirm that the vibration channel returns a plausible reading.
5. Compare the reading with the pre-maintenance baseline where available.
6. Check for excessive noise, unstable output, or an open/short indication.
7. Verify alarm and trip channels where applicable.
8. Record the final vibration reading and channel status.

⚠️ If the channel shows an abnormal reading immediately after cable replacement, check the connector seating, cable continuity, probe compatibility, and proximitor configuration before changing alarm settings.

Frequently Asked Questions

Q1. What is Bently Nevada 113819-01?

Available industrial listings identify 113819-01 as a Proximitor Sensor Extension Cable used in Bently Nevada eddy-current vibration measurement systems.

Q2. Is 113819-01 a vibration sensor?

The more specific available listing identifies it as an extension cable, not the probe itself. Another distributor incorrectly describes the same number as a vibration transmitter/sensor assembly, so the physical part and OEM documentation should be checked before relying on that classification.

Q3. Can I replace 113819-01 with ordinary coaxial cable?

That should not be assumed. The available product description specifically states that 113819-01 is a matched cable intended for the Bently Nevada eddy-current sensor system. Cable impedance and signal characteristics can affect the measurement loop.

Q4. What equipment does 113819-01 connect?

It is described as connecting the vibration probe head and proximitor monitoring module within an eddy-current vibration measurement loop.

Q5. What cable length is 113819-01?

I could not verify a reliable published cable length for the exact 113819-01 from the sources located. Do not infer the length from another Bently Nevada cable part number.

Q6. Can I hot-swap this cable?

Treat the circuit as not hot-swappable unless the applicable Bently Nevada system documentation explicitly permits it. Isolate the associated monitoring circuit before disconnecting the cable.

Q7. What should I verify before ordering?

At minimum, provide the supplier with 113819-01, photographs of both connectors, the connected probe and proximitor part numbers, cable length, and the equipment/application where it is installed. This avoids confusing the cable with similarly numbered Bently Nevada vibration-monitoring components.
