Competitive Advantage

• Stainless Steel Armor: Provides robust protection for the integrated lead against physical abuse, crushing, and harsh operational wear.
  Confined Space Suitability: Compact 5mm probe tip configuration permits installation in narrow machine casing spaces where standard 8mm probes cannot fit.
  Premium Core Insulation: Employs high-quality Tefzel insulation on the 95-ohm coaxial cable to deliver maximum abrasion resistance and electrical stability.
  API 670 Compatibility: Fully satisfies industry-standard requirements for mechanical configuration, linearity, and temperature stability.

System Compatibility and Alternative Models

• System Compatibility
• Connects to 7200 series 21747 extension cables to achieve complete 5-meter or 9-meter overall loop lengths.
  Fully compatible with Bently Nevada 18745 Proximitor Sensors.
  Interfaces directly with legacy 3300 and 9000 machinery protection monitoring systems.

Alternative Models & Differences

• 21500-00-16-05-02: Identical mechanical specification but configured with an unarmored standard leading coaxial cable.
  21505-00-16-05-02: Features a larger 8mm probe head diameter with a 3/8-24 UNF thread for extended linear tracking.
  21501-00-30-05-02: Offers an extended 3.0-inch overall case length instead of the short 1.6-inch case body.

Installation & Troubleshooting FAQ

Q1: What is the correct target calibration setting for a standard 7200 series proximity probe system?
A1: The system is standard-calibrated for an AISI 4140 steel target at +22°C (+72°F) with a nominal scale factor of 200 mV/mil (7.87 V/mm).
Q2: What is the minimum recommended bend radius for the probe cable during routing?
A2: The minimum bend radius is 1 inch for an unarmored configuration, but extra care must be taken with the armored sleeve to prevent internal pinching.
Q3: Why does the proximity sensor signal show distortion or dampening near machine housings?
A3: If the side clearance or counterbore diameter is too tight, the probe tip's radio frequency field will couple with the surrounding metallic walls, reducing sensitivity.
