Introduction
The Bently Nevada 330535-25-01 Standard Temperature Cable is an industrial sensor cable designed for reliable signal and power connection within Bently Nevada vibration-monitoring systems. It is particularly suited to installations using compatible Velomitor velocity sensors and associated machinery-monitoring equipment.
As part of the 330535 cable family, this configuration is intended to provide a dependable connection between the field-mounted vibration sensor and monitoring instrumentation. Its standard-temperature construction makes it a practical solution for conventional machinery installations where the cable is not exposed to extreme-temperature conditions.
For maintenance and replacement projects, using a purpose-designed cable assembly such as the 330535-25-01 can help simplify installation, preserve the intended sensor interface, and reduce the uncertainty associated with field-fabricated alternatives.

Replacement of damaged sensor cables
The 25 ft cable length is particularly useful where the monitoring cabinet or interface equipment is positioned some distance from the machine.
Double shielding also makes the cable well suited to industrial environments containing motors, generators, drives, control cabinets, and other potential sources of electrical interference.
Advantages
Extended Installation Reach
Compared with shorter sensor cables, the approximately 7.6 m (25 ft) configuration gives maintenance engineers more freedom when routing a sensor connection from machinery to a monitoring cabinet or junction location.
Double-Shielded Construction
The double-shielded cable structure helps reduce susceptibility to electromagnetic interference. This is valuable for vibration-monitoring signals that may be routed near power cables, motors, variable-frequency drives, and switching equipment.
Standard-Temperature Design
The standard-temperature construction is appropriate for conventional industrial machinery areas where the cable remains within its specified environmental limits.
For locations exposed to unusually high temperatures, the cable specification should be reviewed carefully before installation.
Purpose-Matched Sensor Connection
The 330535 family is designed around Bently Nevada vibration-monitoring applications, offering a more predictable replacement option than a generic cable assembled solely from matching connector dimensions.
Robust Connector Assembly
The industrial connector arrangement is designed for permanent equipment installations and provides a secure interface between the field sensor and monitoring circuit.
Practical Maintenance Replacement
The factory-style cable assembly can be especially useful during planned maintenance when an existing cable has become brittle, damaged, contaminated, or electrically intermittent.
Reliable Signal Integrity
A correctly matched, shielded sensor cable helps preserve the quality of the vibration signal between the sensor and monitoring system, supporting more consistent condition-monitoring results.
Flexible Machinery Installation
The 25 ft length provides sufficient routing capacity for many pump, motor, compressor, and generator installations while leaving room for sensible cable management and strain relief.
Technical FAQs
1. What is the Bently Nevada 330535-25-01?
The 330535-25-01 is a Standard Temperature Cable intended for compatible Bently Nevada vibration-monitoring and Velomitor sensor installations.
2. How long is the cable?
The nominal cable length is approximately 7.6 m (25 ft).
3. What conductor size does it use?
The cable uses 22 AWG conductors, appropriate for the sensor power and vibration-signal circuit.
4. Is the cable shielded?
Yes. The configuration uses a double-shielded cable construction, helping protect the signal against electrical interference in industrial environments.
5. What type of connector is used?
The cable is associated with a 2-pin MIL-C-5015 style industrial connector arrangement for compatible vibration-sensor systems.
6. Is the 330535-25-01 designed for high-temperature applications?
No assumption should be made that it is suitable for high-temperature service. It is identified as a Standard Temperature Cable, so the actual installation temperature should be compared with the applicable cable specification.
7. Where can this cable be used?
Typical installations include motors, pumps, compressors, fans, blowers, generators, gearboxes, and other rotating machinery equipped with compatible vibration sensors.
8. What are the approximate dimensions?
The principal dimensional specification is the 7.6 m (25 ft) nominal length. The exact cable diameter depends on the finished cable construction and termination.
9. What is the approximate weight?
The complete cable assembly can be estimated at approximately 0.4–0.6 kg, although actual supplied weight may vary according to connector and packaging configuration.
10. What should be verified before replacing an existing cable?
Confirm the part number, cable length, conductor construction, shielding, connector configuration, sensor compatibility, temperature environment, and routing requirements. Matching the cable length alone does not guarantee electrical or mechanical compatibility.
