Features:

  • Patented TipLoc and CableLoc Technologies
  • Corrosion-Resistant ClickLoc Connection System
  • Extreme Temperature Resistance and API 670 Compliance
Utilizing the patented TipLoc molding process and CableLoc design, this technology ensures extremely high structural strength at the probe tip-to-cable connection. This design provides a pull strength of up to 330 N (75 lbf), significantly improving the probe's durability in vibrating environments and effectively preventing cable damage from pulling or fatigue.

Equipped with gold-plated ClickLoc connectors with connector protectors, the probes lock in place with a simple "click" sound. This tool-free design ensures a secure connection, preventing loosening due to equipment vibration, while its corrosion resistance guarantees long-term reliability in humid and oily environments.

Using FEP insulated cable, the probe operates over a temperature range of -52°C to +177°C, enabling it to withstand the high-temperature environments of equipment such as steam turbines and gas turbines. The system performance fully complies with the American Petroleum Institute (API) 670 standard, ensuring industry-leading levels of linear range, accuracy, and temperature stability.

The 330101-12-28-10-02-00 Bently Nevada3300 XL 8 mm Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Reliable Connection with ClickLoc Gold-plated ClickLoc connectors provide a corrosion-resistant, locking mechanism that prevents loosening due to vibration — requiring only finger-tight torque.
  • Designed to meet European CE mark requirements without shielded conduit or metal housings, ensuring signal integrity even in electrically noisy industrial environments.
  • Wide Operating Temperature Range Standard probe supports -52°C to +177°C (-62°F to +350°F) , suitable for high-temperature turbine and compressor applications.
  • Less than 3% change in Average Scale Factor (ASF) after 56 days of 93% relative humidity testing per IEC 68-2-3.
  • Rated for 330 N (75 lbf) tensile strength between probe case and lead, with rugged PPS tip and stainless steel (AISI 303/304) housing for mechanical abuse resistance.
  • Optional FluidLoc & ETR for Harsh Conditions FluidLoc cable option prevents oil leakage through the cable interior; Extended Temperature Range (ETR) option supports probe tip up to +218°C (+425°F) and cable up to +260°C (+500°F) .
Description
This Bently Nevada 330101-12-28-10-02-00 is a key component of the Bently Nevada 3300 XL 8 mm eddy current sensor system, providing an output voltage proportional to the distance from the measured conductive surface and simultaneously measuring static position and dynamic vibration values. All 3300 XL components are fully interchangeable, allowing for probe, extension cable, and preamplifier replacements without separate calibration, greatly simplifying field maintenance.

Addressing the complexities of industrial environments, the Bently Nevada 330101-12-28-10-02-00 Proximity Probe employs advanced mechanical manufacturing processes. It utilizes TipLoc molding technology to securely bond the PPS probe tip to the housing and features a CableLoc design, providing a pull strength of up to 330 N (75 lbf) to effectively prevent cable detachment. Its standard cable uses FEP insulation and can withstand extreme temperatures from -52°C to +177°C, making it suitable for high-temperature applications such as steam turbines and compressors.

The Bently Nevada 330101-12-28-10-02-00 Proximity Probe is equipped with a corrosion-resistant, gold-plated ClickLoc connector and comes pre-installed with a connector protector. The ClickLoc connector features a patented locking mechanism that allows for easy installation simply by tightening it with your fingers until you hear a "click," preventing the connection from loosening without the need for special tools. It also boasts excellent resistance to radio frequency interference, ensuring signal purity even when installed inside a fiberglass housing.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the typical application of the 330101-12-28-10-02-00 probe?
This probe is primarily used for non-contact vibration and position measurement in rotating machinery, including steam turbines, gas turbines, compressors, pumps, and fans. It is ideal for radial vibration, axial (thrust) position, and Keyphasor speed reference measurements, especially in fluid-film bearing machines.
Can this probe be used as a direct replacement for older non-XL 3300 series probes?
Yes. The 3300 XL 8 mm probe is electrically and mechanically interchangeable with non-XL 3300 series 5 mm and 8 mm probes. However, when mixing XL and non-XL components, the system performance will be limited to the specifications of the non-XL system.
What is the temperature rating of this probe?
The standard 330101 probe (with FEP cable) has an operating and storage temperature range of -52°C to +177°C (-62°F to +350°F). For higher temperature applications (up to +218°C / +425°F at the tip), Bently Nevada offers an Extended Temperature Range (ETR) probe version.
What is the recommended target material for calibration?
By default, the 3300 XL system is factory calibrated to AISI 4140 steel. Calibration to other target materials is available upon request. Using non-standard target materials may affect system accuracy and interchangeability.
What is the linear range and scale factor of this probe?
The linear range is 2 mm (80 mils) , starting from approximately 0.25 mm (10 mils) from the target. The standard Incremental Scale Factor (ISF) is 7.87 V/mm (200 mV/mil) with an interchangeability error of ±5% over 0°C to +45°C.
