Bently Nevada 31000 Proximity Probe Housings: Robust Protection for 3300 XL Sensors

Key Features & Environmental Tolerance

• Rugged Construction: The housing uses glass-reinforced Polyphenylene Sulfide (PPS) with conductive fibers. Stainless steel sleeves (AISI 304, 303) resist corrosion. This build withstands harsh industrial conditions.
• Certified Protection Ratings: It meets Type 4X standards per CSA and IP66 ratings. These certifications confirm protection against water jets and corrosive agents. The design also meets CENELEC EN50014 for electrostatic dissipation in hazardous areas.
• Proven Impact Strength: BASEEFA certified it to endure two 4 Joule impacts at extreme temperatures. CSA verified a 7 Joule impact resistance at room temperature. This durability protects the internal probe from physical damage.
• Wide Temperature Range: The assembly operates reliably from -51°C to +105°C. This broad range suits both freezing outdoor installations and high-heat machinery applications.

Frequently Asked Questions (FAQ)

• Q: What probe does the 31000-28-10-00-133-03-02 work with?
  A: This housing is specifically engineered for the Bently Nevada 3300 XL 8 mm probe series. It ensures proper fitment and sealing for accurate vibration measurement.
• Q: Is this housing suitable for outdoor use?
  A: Yes. Its Type 4X and IP66 ratings make it ideal for outdoor or washdown environments. The materials resist corrosion and the seal prevents water ingress.
• Q: What is the function of the probe penetration option '133'?
  A: The 133 indicates a 13.3-inch probe penetration length. This defines how far the probe tip extends from the housing mounting surface into the measurement area.
• Q: Can I use this in a hazardous area?
  A: The housing carries a CENELEC EN50014 rating for electrostatic dissipation. This makes it suitable for installation in hazardous locations with plastic materials.
• Q: What thread size do I need on my machine?
  A: You need a matching 3/4-14 NPT female thread. The included reducer allows you to adapt down to a 1/2-14 NPT connection if required.
