The factory-calibrated sensor requires no field adjustments and maintains accuracy across wide temperature swings, reducing commissioning time and long-term maintenance costs.

Common Questions

Q: What gap voltage does this probe produce?
A: The probe generates -7.87 V/mm when used with compatible 3300 XL proximitor modules, providing industry-standard output for most monitoring systems.

Q: Can I use this probe in hazardous areas?
A: Yes, when installed with appropriate barriers and certified proximitor housings, it meets Class I Division 2 requirements for hazardous location deployment.

Q: What is the recommended target material?
A: The probe is calibrated for use with 4140 alloy steel shafts. Consult factory documentation for alternative target materials and corresponding calibration factors.

Q: How do I verify probe functionality?
A: Use a Bently Nevada TK-3 test kit or equivalent to measure gap voltage at known distances. The probe should produce linear output within specified tolerances.
