Common Questions
- What is the difference between 330878-91-00 and 330878-91-05? The -91-00 has no agency approvals; the -91-05 includes multiple international approvals for hazardous locations.
- Is it suitable for turbine differential expansion? Yes, the 50 mm system is specifically designed for steam turbine differential expansion and axial position monitoring.
- What power supply is required? Standard -17.5 to -26 V DC supply at 12 mA maximum, typically -24 V DC.
Mounting Steps
- Clip the Proximitor Sensor onto the DIN rail in the control cabinet.
- Connect the 50 mm probe extension cable to the input connector.
- Wire the voltage output to the monitoring system input.
- Apply -24 V DC power supply.
- Verify system operation by checking the gap voltage at the monitoring display.
Buying Advice
- Select the 330878-91-00 for general-purpose 50 mm applications without hazardous area certification needs.
- For installations requiring agency approvals, choose the 330878-91-05.
- Confirm the probe, extension cable, and Proximitor are all 3300 XL 50 mm series for guaranteed system performance.
