Standard Mount Probe - 21505-22-55-10-02 - Bently Nevada

Bently Nevada 21505-22-55-10-02 Industrial Vibration Probe

Key Specifications

Enhanced Durability: Features 2.2" (55.88mm) unthreaded section + 5.5" (139.7mm) stainless steel case. 1m armored cable with +10"/-4" length tolerance for flexible installation.

Performance Excellence

Ultra-Precise Sensing: Maintains ±4% scale factor accuracy across 10-80 mils range. Achieves 0.8 mils (0.02mm) linearity error when system-calibrated, 2.3 mils (0.06mm) with component interchangeability.

Power Dynamics

Low-Energy Operation: Requires only -17.5V to -26V DC power supply with max 12mA current draw. Stable output from 0.25mm to 2.0mm gap distances.
