330101-00-24-10-02-00 Bently Nevada 8mm Proximity Probe

Product Overview

The 330101-00-24-10-02-00 is an 8 mm proximity probe from the industry-standard 3300 XL Proximity Transducer System manufactured by Bently Nevada. Designed for precise eddy current displacement and vibration monitoring on rotating machinery, this probe features patented TipLoc and CableLoc technologies for exceptional mechanical integrity. With a cable weight density of 323 g/m (0.71 lb/ft), it is configured with 0.0 in unthreaded length, a 2.4 in case length, a 1.0 m (3.3 ft) cable, and a Miniature coaxial click-loc connector, delivering high accuracy across demanding industrial environments.

Core Technical Advantages

• TipLoc & CableLoc Construction: Patented molding processes secure the probe tip to the main body and ensure a 75 lbf (330 N) pull strength between the cable and probe head.
• Durable PPS Encapsulation: Features an 8 mm polyphenylene sulfide (PPS) tip with 2.5x thicker encapsulation than standard 5 mm models for higher chemical and physical endurance.
• Optimized Cable Weight: Standard cable linear weight density of 323 g/m (0.71 lb/ft) minimizes dynamic mechanical loading on terminal routing.
• Broad Operating Temperature: Standard probe construction operates reliably from -52 °C to +177 °C (-62 °F to +350 °F) to handle extreme machinery casing environments.
• Precision Electrical Output: Provides a stable linear range of 0.25 mm to 2.3 mm (-1 V to -17 V output voltage curve) for sensitive shaft vibration measurements.

Technical Specifications

Industrial Solutions

• Steam & Gas Turbines: Measures radial shaft vibration and axial thrust position for critical machinery protection.
• Centrifugal Compressors: Monitors high-speed shaft stability and dynamic displacement under varying process loads.
• Industrial Gearboxes: Provides non-contact shaft tracking inside high-vibration power transmission housings.
• Large Pumps & Motors: Detects bearing wear, unbalance, and misalignment before catastrophic mechanical failure.

Wiring & Installation

Pre-Installation Inspection & Safety

Isolate and lock out machine drive systems before accessing internal bearing housings. Clean the mounting port threads and check that the probe tip and coaxial cable are free of contamination or physical damage.

Mechanical Mounting & Gap Setting

Thread the stainless steel case into the rigid mounting bracket or housing port. Adjust the mechanical gap relative to the target shaft using dynamic voltage readings or feeler gauges to center the sensor within its 0.25 to 2.3 mm linear window before locking down jammed nuts.

Coaxial Cable Routing & Weight Support

Route the 1.0 m cable (323 g/m weight rating) away from sharp casing edges and high-voltage power lines. Support cable weight to maintain minimum bend radii and prevent coaxial core deformation.

Connector Lock & Proximitor Interface

Connect the Miniature coaxial Click-Loc connector to the extension cable leading to the 3300 XL Proximitor Sensor. Hand-tighten until the tactile click mechanism engages, ensuring a moisture-resistant seal and reliable signal path.

Engineering Advantages

• High Mechanical Pull Resistance: CableLoc design resists up to 75 lbf (330 N) pull force, preventing field failures during cable pull-through.
• Rugged Material Selection: AISI 303/304 stainless steel case (Rockwell B85) resists severe atmospheric corrosion and mechanical distortion.
• Stable Frequency Response: Maintains linear eddy-current output from DC static position up to high dynamic vibration frequencies.

Technical FAQs

Q1: What does option code 330101-00-24-10-02-00 specify?
A1: 0.0in unthreaded, 2.4in case, 1.0m cable, Click-Loc connector, no approvals.

Q2: Is an extension cable required for system operation?
A2: Yes. Matching 4m or 8m extension cables achieve mandatory 5m or 9m system length.

Q3: What is the weight specification of the probe cable?
A3: The standard cable linear density is 323 g/m (0.71 lb/ft).
