330101-00-08-20-02-CN | Bently Nevada 8 mm Probe 2.0m Cable

What Is the 330101-00-08-20-02-CN?

When machinery reliability is critical, the 330101-00-08-20-02-CN from Bently Nevada provides precise vibration measurement. This 3300 XL 8 mm probe features a 3/8-24 UNF thread and a 2.0 meter cable. It is designed without armor for standard industrial environments. The probe delivers a linear range of 2 mm (80 mils) starting at 0.25 mm from the target. With an incremental scale factor of 7.87 V/mm (200 mV/mil), it ensures accurate data for predictive maintenance.

One standout spec is the patented CableLoc design providing 330 N (75 lbf) pull strength. This reduces cable failure risk in high-vibration applications.

Real-World Applications

Industries rely on the 330101-00-08-20-02-CN for turbine, compressor, and pump monitoring. It excels in rotating machinery where early fault detection prevents costly downtime. For example, in a petrochemical plant, this probe helps identify bearing wear before catastrophic failure. Its robust PPS tip withstands harsh conditions, ensuring long-term accuracy.

Installation Guide

Mount the probe with recommended torque of 11.2 N•m (100 in•lbf) for forward mounted probes. Use three-conductor shielded triad cable for field wiring, up to 305 meters (1,000 feet) from the Proximitor sensor. Ensure proper thread engagement to avoid damage. Always follow Bently Nevada's manual for gap setting at -9 Vdc (approximately 1.27 mm).

Routine Care & Reliability

Inspect the probe cable and connector periodically for wear. The CableLoc design enhances pull strength, but environmental factors like humidity (tested to <3% ASF change at 93% RH) can affect performance. For extended temperature ranges, the probe operates up to +218°C at the tip. Regular calibration checks maintain the ±5% scale factor accuracy.

Compatible Systems

The 330101-00-08-20-02-CN integrates with Bently Nevada 3300 XL Proximitor sensors and monitoring systems. It works with standard 5 or 1 meter system configurations. For 9 meter systems, the scale factor tolerance widens to ±6.5%. Field wiring length affects frequency response, so consult the datasheet for rolloff at high frequencies.

Common Questions About the 330101-00-08-20-02-CN

Q: What is the linear range of this probe?

A: The linear range is 2 mm (80 mils), starting at 0.25 mm from the target and extending to 2.3 mm.

Q: Can this probe be used in high-temperature environments?

A: Yes, the standard probe operates from -52°C to +177°C, while the extended temperature range probe reaches +218°C at the tip.

Q: What connector type does the 330101-00-08-20-02-CN use?

A: It uses a miniature coaxial ClickLoc connector with standard cable.

Q: Is the probe resistant to oil leakage?

A: An optional FluidLoc cable prevents oil leakage through the cable interior; the standard model does not include this feature.

Q: How do I verify the probe's DC resistance?

A: Measure resistance between center and outer conductors; it should be 7.88 ± 0.50 Ω for the 2.0 m length.
