Common Questions
- What is the difference between the 25 mm and 50 mm systems? The 25 mm system provides 12.7 mm linear range with 0.787 V/mm sensitivity; the 50 mm system provides 25.4 mm range with 0.394 V/mm sensitivity.
- What is the minimum target size? The 25 mm probe requires a minimum target diameter of 76 mm (3 in) for accurate measurements.
- Can it be used with 3500 monitoring systems? Yes, it is fully compatible with Bently Nevada 3500 series machinery protection systems.
Mounting Steps
- Install the panel-mount Proximitor base in a vibration-isolated location.
- Connect the 3300 XL 25 mm extension cable from the probe to the Proximitor.
- Wire the output signal to the monitoring system input module.
- Apply -24 V DC power supply.
- Verify linearity across the measurement range using the system diagnostics.
Buying Advice
- Select the 330850-90-CN for large displacement applications up to 12.7 mm requiring China approvals.
- For DIN rail mounting, choose the 330850-91-CN variant.
- Ensure probe and extension cable are both 3300 XL 25 mm series for proper system matching.
