The 330850-51-05 is a high-performance Bently Nevada 3300 XL 25mm Proximitor Sensor featuring a 5.0-meter system loop and multi-agency explosion-proof certifications. Fully compatible with 3300 XL 25mm proximity probes, this high-density DIN-rail mounted module works seamlessly inside dense instrumentation cabinets to deliver exceptional RFI/EMI immunity and stable industrial differential expansion monitoring.
Specifications
- Proximitor Sensor Input：Accepts one noncontacting 3300 XL 25 mm Proximity Probe and Extension Cable.
Power：Requires -17.5 Vdc to -26 Vdc without barriers at 12 mA maximum consumption, -23 Vdc to -26 Vdc with barriers. Operation at a more positive voltage than -23.5 Vdc can result in reduced linear range.
Supply Sensitivity：Less than 2 mV change in output voltage per volt change in input voltage.
Output resistance：50 W - Operating Temperature：-51°C to +100°C (-60°F to +212°F)
- Dimension：8.8x3.6x7cm
- Weight：0.22kg
Specific Application
- Differential expansion (DE) monitoring on mid-size to large steam turbine generators to track growth variance between the turbine rotor and stator casing.
- High-density cabinetry setups where advanced physical packaging allows multiple sensors to be packed closely on a standard 35mm DIN rail.
- High-reliability industrial machinery monitoring environments requiring advanced immunity to nearby radio frequency interference (RFI) without metallic shielding.
System Compatibility & Alternatives
- System Compatibility: The sensor accepts one non-contacting 3300 XL 25mm proximity probe and its matching extension cable to form a complete 5.0-meter transducer system. It provides a standard 0.787 V/mm (20 mV/mil) output that is identical to older 7200 25mm, 7200 35mm, and legacy 25mm DE Integral systems, allowing easy upgrades without updating the monitor configuration. When upgrading, all loop components must be replaced with 3300 XL series hardware.
- Alternative Model: 330850-50-05
- Difference from Alternative: The 330850-51-05 is configured for DIN rail mounting with a specialized clip base for 35mm rail structures. The alternative 330850-50-05 model is built for a traditional panel mount configuration, featuring an isolated base plate with a 4-hole mounting footprint designed to slide directly onto back panels or within custom bulkhead housings.
