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

  1. Clip the Proximitor Sensor onto the DIN rail in the control cabinet.
  2. Connect the 50 mm probe extension cable to the input connector.
  3. Wire the voltage output to the monitoring system input.
  4. Apply -24 V DC power supply.
  5. 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.
