3300 XL Proximitor Sensor - Model 21508-02-12-10-02
Bently Nevada 21508-02-12-10-02 represents the industry benchmark in proximity transducer technology. This 3300 XL series proximitor converts raw probe signals into conditioned outputs for vibration analysis, shaft position monitoring, and machinery protection across critical rotating equipment.
Core Specifications
Model Number: 21508-02-12-10-02
Product Line: 3300 XL Proximity Transducer System
Output Signal: -2 to -18 VDC proportional to gap
Scale Factor: 200 mV/mil (7.87 mV/μm) typical
Frequency Range: 0 to 10 kHz (-3 dB)
Power Supply: -24 VDC ±5% @ 25 mA
Operating Temp: -30°C to +65°C (-22°F to +149°F)
Mounting: DIN rail or panel mount options
Certifications: API 670 compliant, CE marked
Real-World Performance
Turbine Monitoring: In gas and steam turbine applications, the 21508-02-12-10-02 delivers microsecond-level response times essential for detecting bearing failures, rotor rubs, and critical speed transitions before catastrophic damage occurs.
Compressor Protection: Petrochemical facilities rely on this proximitor to track shaft axial position and radial vibration in centrifugal compressors handling volatile process gases—where a single failure can cost millions in downtime and safety incidents.
Pump Surveillance: From boiler feedwater pumps to crude oil transfer systems, this sensor provides the continuous condition data that predictive maintenance teams use to schedule repairs during planned outages rather than emergency shutdowns.
Why Engineers Specify This Model
The 21508-02-12-10-02 isn't just a signal conditioner—it's a critical link in your machinery protection chain. Its low-noise circuitry eliminates false trips that plague lesser systems, while its wide frequency response captures both slow-roll data and high-frequency bearing defects in a single channel.
Field-proven across millions of operating hours, this proximitor maintains calibration accuracy even in electrically noisy environments with nearby VFDs, welders, and high-voltage switchgear. The result? Fewer nuisance alarms, higher operator confidence, and genuine protection when it matters most.
System Architecture
Pair this proximitor with any Bently Nevada 8mm proximity probe and appropriate extension cables to create a complete measurement channel. The system integrates seamlessly with 3500 rack monitoring systems, standalone trip modules, or direct PLC/DCS inputs via industry-standard voltage outputs.
Multiple proximitors can share common power supplies and ground references, simplifying multi-channel installations on complex machinery trains. Diagnostic LEDs provide instant visual confirmation of power, OK status, and alarm conditions without requiring test equipment.
Quality Assurance
Every 21508-02-12-10-02 ships with factory calibration certificates traceable to NIST standards. Rigorous burn-in testing eliminates infant mortality failures, while conformal coating protects electronics from moisture, dust, and chemical exposure in harsh industrial atmospheres.
Product Status: New, factory-sealed unit with full manufacturer warranty and technical support.
