Mechanical and Environmental Ratings

This probe withstands extreme conditions. Consequently, it performs reliably in harsh industrial environments.

• Operating Temperature (Standard Probe): -52°C to +177°C (-62°F to +350°F)

• Storage Temperature (Standard Probe): -52°C to +177°C

• Extended Temperature Range (Tip): -52°C to +218°C (-62°F to +425°F)

• Extended Temperature Range (Cable): -51°C to +260°C (-60°F to +500°F)

• Pressure Capability: Seals differential pressure with a Viton O-ring.

• Relative Humidity: Less than 3% change in ASF after 56 days at 93% humidity (IEC 68-2-3).

• Tensile Strength: 330 N (75 lbf) from case to lead; 270 N (60 lbf) at connectors.

Additionally, the probe shows strong resistance to magnetic field interference. For instance, at a 10-mil gap, the probe output voltage measures only 0.0004 Mil pp/Gauss. Meanwhile, at a 90-mil gap, it reaches just 0.0045 Mil pp/Gauss. This stability ensures consistent readings across varying conditions.

Hazardous Area Approvals

The 330105-02-12-50-12-CN carries important certifications for hazardous locations. Specifically, it meets Class I, Zone 0 and Class I, Zone 2 requirements when properly installed.

For intrinsically safe installations (ia) with zener barriers or galvanic isolators:

• Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga

• Class I, Groups A, B, C, and D

• Class II, Groups E, F, and G

• Class III

For non-incendive installations (nA, ec) per drawing 140979:

• Class I, Zone 2: AEx/Ex nA IIC T5...T1 Gc

• Class 1, Division 2, Groups A, B, C, D

• Class I, Zone 2: AEx/Ex ec IIC T5...T1 Gc

Temperature Classification Schedule

The probe's temperature classification varies with ambient conditions. For EPL Ga and Gc environments, the classifications range from T1 (-55°C to +232°C) down to T5 (-55°C to +40°C). For EPL Dc environments, the classifications include T280°C through T90°C at specified ambient temperatures. Always match the classification to your application's requirements.

Important Note About FluidLoc Cable

The FluidLoc cable option (Code 12) is not necessary for most 330105 and 330106 installations. This is because the probe sleeve already provides adequate sealing. Consider your application carefully before ordering this option. Only select FluidLoc when additional moisture or fluid ingress protection is absolutely required.

Installation and Mounting Guide

Proper installation of the 3300 XL probe ensures optimal performance and longevity. First, verify the 3/8-24 UNF thread compatibility with your mounting hardware. Next, clean the target surface thoroughly to remove any contaminants. Furthermore, maintain the correct gap setting as specified in your system documentation. Never exceed the 0.563-inch maximum thread engagement. The reverse mount design demands specific clearance behind the probe tip for proper operation. Finally, connect the Bently Nevada 330105 to the appropriate extension cable using the ClickLoc connector. For FluidLoc models, ensure the sealing mechanism engages properly.

Frequently Asked Questions

1. What is the total length of the Bently Nevada 330105-02-12-50-12-CN?
This probe has a total length of 5.0 meters (16.4 feet), making it suitable for installations requiring extended cable reach.

2. Do I need the FluidLoc cable option for my application?
For most 330105 and 330106 installations, FluidLoc is not required due to the existing probe sleeve protection. Only order this option if your application faces significant moisture or fluid exposure.

3. What hazardous area approvals does this model carry?
This probe carries Class I, Zone 0 and Class I, Zone 2 approvals for both intrinsically safe and non-incendive installations. Refer to the approvals section above for complete details.

4. What is the nominal DC resistance of this 5-meter probe?
The nominal DC resistance (RPROBE) is 8.73 ± 0.50 Ω, measured from center conductor to outer conductor.

5. What is the temperature limit for this probe?
The standard probe operates from -52°C to +177°C (-62°F to +350°F). The extended range tip reaches up to +218°C. However, exposing the probe below -34°C may cause premature seal failure.
