Products Description
Bently Nevada 330103-07-18-10-02-00 Proximity Probes
The 330103-07-18-10-02-00 is an inductive displacement probe intended to establish a fixed electrical reference relative to a moving metallic surface. Its operation is based on controlled electromagnetic coupling between the probe tip and the target material. The probe itself contains no logic or compensation circuitry; its sole responsibility is to deliver a repeatable raw signal proportional to physical separation.
The dimensional format and internal coil structure are optimized for installations where probe-to-target distance must remain measurable despite shaft motion, casing expansion, or speed variation.
With over 50 million in inventory, PLC EXPORT delivers only brand-new, authentic components- ready to ship,
rigorously tested, and backed by professional technical support.

Physical Construction Characteristics
The probe consists of a cylindrical metallic body housing a precision-wound sensing coil and magnetic core. The tip geometry defines the active sensing zone and directly influences output linearity. Threaded mounting allows rigid fixation to machine housings while preserving axial alignment.
Materials are selected to maintain mechanical form and electromagnetic behavior under continuous exposure to vibration, temperature gradients, and lubricated environments.
Measurement Behavior
The probe generates a variable electrical response as the metallic target alters the electromagnetic field at the sensing tip. This response is:
- Continuous rather than discrete
- Dependent on gap distance, not motion direction
- Independent of shaft speed within the operating envelope
- All interpretation, scaling, and validation of this signal occur outside the probe in associated electronics.
Role Within a Measurement Chain
The probe occupies the first physical boundary of a displacement measurement system:
Metallic Target Surface
→ Electromagnetic Field Interaction
→ Probe Output Signal
→ External Signal Conditioning
→ System-Level Processing
Any mechanical instability, misalignment, or deformation at the probe level directly affects signal integrity downstream. For this reason, probe rigidity and electromagnetic consistency are prioritized over functional complexity.

Installation Constraints
Correct operation depends on:
- Axial alignment between probe tip and target surface
- Maintaining the designed working gap
- Avoidance of lateral mechanical stress on the probe body
- Cable routing that prevents induced noise or conductor fatigue
Once installed and secured, the probe does not require operational adjustment.
Advantages / Value Highlights
By adapting to restricted or inverted mounting positions, the 330105-02-12-05-02-00 allows monitoring in areas previously inaccessible to standard probes. Its stable, non-contact sensing minimizes mechanical wear while delivering a consistent analog signal. This combination ensures measurement integrity in complex industrial installations, supporting accurate system interpretation.
Integration Notes
- Intended for use with matched proximity signal conditioning hardware
- Functions purely as a sensing element, not a diagnostic device
- Suitable for dense installations where multiple probes operate in close proximity without mutual interference

Common problems
Q1: Does this probe include any internal amplification or signal conditioning?
A1: No. The probe functions solely as an electromagnetic transducer. Signal amplification, linearization, and scaling are handled entirely by external conditioning electronics.
Q2: Is the probe output affected by shaft rotational speed?
A2: The probe response is governed by the distance between the probe tip and the metallic target. Rotational speed does not directly influence the output as long as operation remains within the specified operating range.
Q3: Does probe orientation influence measurement performance?
A3: The sensing principle is orientation-independent. However, installation angle and mechanical alignment can affect gap consistency, which in turn influences signal linearity.
Q4: Can multiple probes be installed in close proximity without interference?
A4: Yes. When installed according to spacing and cabling guidelines, the probe's electromagnetic field remains localized and does not significantly interfere with adjacent probes.
Q5: Is long-term signal drift expected from the probe itself?
A5: Under normal environmental and mechanical conditions, the probe's electromagnetic characteristics remain stable. Apparent drift is more commonly associated with mechanical changes or external electronics.
Q6: Can the probe be replaced independently of the existing electronics?
A6: Yes, provided the replacement probe is compatible with the installed signal conditioning hardware, probe replacement can be performed without changing the electronics.
Q7: Does the probe response depend on the target material?
A7: Yes. The electromagnetic response varies with the electrical properties of the target material. Consistent target material is required to maintain predictable output behavior.
