3. Product Description
The 330101-00-14-20-02-CN is a non-contact proximity probe that operates on the eddy current principle. It measures the relative movement of a conductive target, typically a rotating shaft, with very high precision and reliability.
The sensor consists of a probe, an extension cable, and a proximitor (signal conditioner), all of which form a fully calibrated system. It is engineered for demanding environments where high-temperature resilience, signal integrity, and mechanical durability are paramount.
4. Applications
-
Power generation – Steam and gas turbines, generators
-
Oil & gas – Compressors, pumps, and turbo-expanders
-
Chemical plants – Reactors, mixers, fans
-
Marine – Main propulsion shafts, turbines
-
Mining and industrial – Motors, blowers, gearboxes
-
Aerospace / R&D – Test stands, turbines, high-speed rotors
5. Advantages
-
High Accuracy & Repeatability
Ensures precise shaft displacement and vibration measurements under all operating conditions. -
Wide Temperature Range

8. FAQs (Q&A Format)
Q1: What is the maximum measurable distance of this probe?
A: The linear measuring range is approximately 0.25 mm to 2.3 mm. Beyond that, the signal may become nonlinear or unreliable.
Q2: What is the recommended gap voltage?
A: A typical recommended gap voltage is around –9 Vdc, corresponding to a 1.27 mm (50 mils) shaft gap.
Q3: How much temperature can it withstand?
A: Standard probe handles up to +177°C. With high-temp options, the tip can withstand +218°C and cables up to +260°C.
Q4: Does cable capacitance affect signal quality?
A: Yes. Higher capacitance can reduce signal fidelity. The standard cable has around 69.9 pF/m capacitance.
Q5: Is it easy to replace if the probe fails?
A: Yes. Thanks to modular design, the probe can be replaced separately. Re-calibration of the gap is recommended.
Q6: Can it work in oily or wet conditions?
A: Yes. The probe is sealed and designed for industrial environments. FluidLoc cable options enhance sealing against fluids.
Q7: Is it suitable for high-vibration machines?
A: Absolutely. It is built to endure high-G vibration and shock.
Q8: How can I detect a faulty probe?
A: Signs include erratic or noisy signal output, drifting voltage readings, or sudden changes in gap voltage. Comparing readings with a known good probe can help isolate the issue.
Q9: Is this model certified for hazardous environments?
A: Yes. The suffix “CN” indicates compliance with Chinese regulatory standards, and many variants also hold international certifications like ATEX, CSA, and IECEx for hazardous locations.
Q10: Why might there be variations in prices for this model?
A: Differences arise from certification versions, cable length options, high-temperature features, suppliers, and whether the product is OEM or aftermarket.
