21505-12-40-10-02 Bently Nevada | Standard Mount Probe

Bently Nevada 21505-12-40-10-02 Probe Proximity Vibration Sensor

Core Features

Premium Construction: Stainless steel armored cable (1.0 metre length, +10"/-4" tolerance) ensures durability in harsh environments. Features 3/8-24 threaded tip with 8mm diameter for secure mounting.

Technical Superiority

Precision Output: Delivers 200 mV/mil sensitivity (±4% system-calibrated) with ultra-low linearity error: 0.8 mils (0.02mm) in calibrated systems, 2.3 mils (0.06mm) with interchangeability.

Power & Efficiency

Optimized Energy Use: Operates on -17.5V to -26V DC with max 12mA consumption. Maintains stable performance from 10 mils (0.25mm) proximity up to 80 mils (2.0mm) calibrated range.

Environmental Resilience

Extreme Temperature Operation:
- Proximitor: -51°C to +100°C
- Probe/Cable: -34°C to +177°C
Chemical resistance against sulfuric acid (10%), MEK, DMF, and ammonium hydroxide.
