Expert Review

The 330172-04-12-05-02-CN is a great short case probe for tight spots. Bently Nevada makes top quality sensors. This probe works from -35°C to +177°C. The 1.2 inch case fits where space is small. The PPS tip resists chemicals. Armor cable adds strength. A smart choice for crowded machines.

Manager’s Insight

We recommend this probe for tight mounting locations. The short 1.2 inch case fits where standard 4 inch cases cannot. Country specific approval (CN) meets local rules. ClickLoc connector is easy to use. Stock ready. For tight spaces, this is your best option.

Suitable Devices & Applications

• Small turbines (tight bearing areas)
• Compressors (limited space mounting)
• Gearboxes (internal vibration monitoring)
• Pumps (crowded machine trains)
• Generators (compact sensor placement)
• Rolling mills (restricted access points)

Frequently Asked Questions (FAQ)

Q: Why choose this short case probe?
A: The 1.2 inch case fits tight spots. Standard 4 inch cases may not fit. Measure your space first.

Q: What power supply do I need?
A: Use -17.5 Vdc to -26 Vdc. Less than -23.5 Vdc may reduce linear range. Max 12 mA.

Q: Can this probe work in high heat?
A: Yes. Max probe temp is +177°C. Do not go below -34°C or seal may fail.

Q: What is CN approval?
A: CN means country specific approval. Meets local safety rules for your region.

Q: How tight should I install it?
A: Torque to 5.1 N·m (45 in·lb). Max 7.3 N·m (65 in·lb). Do not over tighten.

Q: What is the warranty?
A: 12 months from invoice date. Covers factory defects. Fast replacement.

Q: How fast do you ship?
A: 12-24 hour dispatch for stock items. Use FedEx, UPS, or DHL. Tracking provided.

Q: Can I bend the cable sharply?
A: No. Min bend radius is 25.4 mm (1.0 in). Sharp bends damage the cable.
