The Bently Nevada 330195-02-12-10-05 represents a specialized variant of the 3300 XL series, featuring a reverse mount configuration that solves common installation challenges in crowded machine casings. This design routes the cable from the back of the probe, allowing engineers to install the sensor in locations where standard straight probes simply cannot fit.
This 8 mm proximity probe delivers precise eddy-current measurements for shaft vibration, thrust position, and eccentricity monitoring. The molded PPS tip encapsulates the sensing coil more thickly than earlier generations, providing superior resistance to mechanical abuse and chemical exposure. Meanwhile, the AISI 303 or 304 stainless steel case offers excellent corrosion protection and structural integrity.
What truly sets this variant apart is its comprehensive approval package. The 330195-02-12-10-05 carries CSA, ATEX, and IECEx certifications, making it suitable for installation in hazardous areas worldwide. The 1.0-meter (3.3 feet) total length provides flexibility for installations requiring longer cable runs without the complexity of extension cables.
The 330195-02-12-10-05 exhibits a nominal DC resistance of 7.59 ± 0.50 Ω from the center conductor to the outer conductor. This precise resistance value ensures optimal matching with Bently Nevada Proximitor systems for accurate signal transmission and measurement linearity.
The probe tip uses PPS (polyphenylene sulfide), a high-performance thermoplastic that maintains its mechanical properties across a wide temperature range. The case material is AISI 303 or 304 stainless steel, both known for their excellent corrosion resistance and strength. The 3/8-24 UNF thread accepts a maximum engagement length of 0.563 inches, preventing damage from over-tightening.
For temperature performance, the standard probe operates from -52°C to +177°C. The extended temperature range option supports up to +218°C at the probe tip and up to +260°C at the cable and connector. However, users should note that exposing the probe to temperatures below -34°C may cause premature failure of the pressure seal, so we recommend maintaining operating temperatures above this threshold.
The reverse mount design offers distinct advantages for machine monitoring. For instance, the cable exits perpendicular to the mounting surface, reducing bending stress and simplifying routing in confined spaces. Additionally, this configuration minimizes the risk of cable damage from rotating components or sharp edges.
Humidity resistance is another strong point of the 330195-02-12-10-05. When tested at 93% relative humidity per IEC standard 68-2-3 for up to 56 days, the Average Scale Factor changes by less than 3%. This stability makes the probe suitable for humid environments such as pulp and paper mills, marine applications, and outdoor installations.
A Viton® O-ring seals the differential pressure between the probe tip and case. Although Bently Nevada does not pressure-test probes before shipment, this sealing system effectively prevents oil and moisture ingress during normal operation. For applications requiring specific pressure testing, please contact the custom design department for special arrangements.
Proper installation of the 330195-02-12-10-05 ensures accurate measurements and long service life. First, confirm that the mounting hole matches the 3/8-24 UNF thread specification. Thread engagement must not exceed 0.563 inches to avoid damaging the probe or the mounting surface.
When positioning the probe, ensure the tip faces the target surface with the correct gap per your Proximitor system specifications. The reverse mount design allows the cable to route away from the sensing area, reducing the risk of interference from rotating components.
For hazardous area installations, follow all applicable safety regulations and use only Bently Nevada extension cables and Proximitor systems to maintain entity parameters and certifications. Avoid exposing the probe to temperatures below -34°C, as this may compromise the pressure seal. For high-temperature applications, we recommend selecting the extended temperature range option.

Q1: What approvals does the 330195-02-12-10-05 carry?
A1: This model carries CSA, ATEX, and IECEx approvals, making it suitable for installation in hazardous areas requiring these international certifications.
Q2: Does this 1.0-meter probe need an extension cable?
A2: No. The 330195-02-12-10-05 has a total length of 1.0 meter, so it functions as a complete one-piece system without requiring an extension cable.
Q3: What is the temperature limit for this probe?
A3: The standard operating range is -52°C to +177°C. However, exposing the probe to temperatures below -34°C may cause premature pressure seal failure. For higher temperatures up to +218°C at the tip, choose the extended temperature range option.
Q4: What makes the reverse mount design different from standard probes?
A4: The reverse mount 330195-02-12-10-05 routes the cable from the back of the probe, allowing installation in tight spaces where standard straight probes cannot fit. This design simplifies cable management in confined machine casings.
Q5: What shipping methods do you offer?
A5: We ship all orders via Fedex, UPS, or DHL with full tracking. Express and economy options are available upon request.
