Beskrivelse

Product Overview

The Bently Nevada 330101-12-40-10-02-CN is a high-precision 3300 XL 8 mm proximity transducer probe engineered for non-contact shaft vibration and position monitoring in critical rotating machinery. Manufactured for demanding industrial environments such as hydroelectric turbines, petrochemical compressors, and steel rolling mills, this sensor delivers real-time eddy current measurements to prevent catastrophic equipment failure.

This specific part configuration (330101-12-40-10-02-CN) features a 1.2-inch unthreaded smooth shaft, a 4.0-inch total case length, a 1.0-meter (3.3 feet) miniature coaxial ClickLoc cable, miniature coaxial connectors without connector protectors, and China-specific (CN) hazardous area approval certification. Built with a lightweight cable design of 323 g/m (11.4 oz/ft) and an approximate total probe weight of 0.23 kg (0.50 lbs), the unit consists of an AISI 304 stainless steel body, a molded Polyphenylene Sulfide (PPS) tip, and a Viton® O-ring seal designed to operate in severe thermal environments from -52°C to +260°C (-62°F to +500°F).

Core Technical Advantages

  • Robust Mechanical Construction: High-strength AISI 304 stainless steel case and PPS tip combined with a cable lock design capable of withstanding 330 N (75 lbf) pull force.
  • High Linear Accuracy: Delivers a precise 7.87 V/mm (200 mV/mil) ±5% output with a linear range of 0.25 mm to 2.3 mm and minimal linearity error (±0.025 mm).
  • Low Signal Loss Transmission: Features low-capacitance cable specs (21.3 pF/ft / 69.9 pF/m) supporting long-distance signal integrity up to 305 meters (1,000 feet).
  • Harsh Environment Protection: Meets IEC 68-2-3 humidity resistance standards (93% RH for 56 days) with minimal Average Scale Factor (ASF) variation in high-moisture settings.

Installation & Gap Calibration Guide

  • Mechanical Threading & Mounting: Thread the 3/8-24 UNF body into the casing or mounting adapter. Ensure the 1.2-inch unthreaded portion aligns smoothly without binding.
  • Gap Calibration: Adjust the mechanical gap to an optimal setting of 1.27 mm (approx. 50 mils) to establish a baseline DC voltage output of -9.00 V DC on the Proximitor Sensor.
  • Cable Connection: Connect the 1.0 m ClickLoc coaxial cable to your extension cabling, observing minimum bend radius limits during field installation.
