- Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±6.5% including interchangeability error, measured over the full linear range from 0°C to +45°C.
- Probe Temperature Range: Operating and storage from -51°C to +177°C (-60°F to +351°F), ensuring performance in extreme environments.
- Probe Pressure Rating: Sealed to 34 Bar (500 psi) nitrogen, with modifications available for higher-pressure applications.
- Probe Tip Material: Alumina ceramic (Al2O3) for wear resistance and thermal stability.
- Probe Case Material: AISI 304 stainless steel for corrosion resistance.
- Probe DC Resistance: 7.59 ± 0.50 ohms from center conductor to outer conductor for a 1.0 meter probe.
Industry Applications
This proximity probe is ideal for monitoring shaft vibration and position in steam turbines, compressors, pumps, and generators. Its ceramic tip provides excellent immunity to shaft surface imperfections and electrical runout, making it a preferred choice in high-speed rotating machinery where precise gap measurements are critical. The 146054-040-10-02-05 also excels in applications requiring hazardous area certifications, thanks to its CSA, ATEX, and IECEx approvals.
Installation & Setup Guidance
Proper installation is key to achieving accurate readings. Mount the probe with the 3/8-24 UNF thread into a suitable bracket or housing, ensuring the target surface is clean and made of AISI 4140 steel for calibrated performance. The maximum thread engagement length is 0.563 inches. Connect the miniature coaxial ClickLoc connector to the extension cable, then route the standard cable away from high-noise sources. Calibrate the system using a Bently Nevada Proximitor sensor and extension cable for optimal linearity.
Maintenance & Reliability
The 146054-040-10-02-05 is built for long-term reliability with its stainless steel case and ceramic tip. Routine inspection should focus on cable integrity and connector cleanliness. The wide operating temperature range and high-pressure seal ensure dependable operation in harsh industrial environments. For maximum service life, avoid exceeding the specified temperature and pressure limits.
Selection Guide & Purchasing Advice
When ordering the 146054-040-10-02-05, verify that the overall case length (4.0 in), total cable length (1.0 meter), connector type (miniature coaxial ClickLoc), and agency approvals (CSA, ATEX, IECEx) match your application requirements. SpareTechPLC offers this probe as a new, original factory-packed unit with a 12-month warranty. Please confirm current lifecycle status and availability with SpareTechPLC before ordering.
