5 Professional FAQs – Selection and Experience

• Q: Can this transducer be submerged in oil or exposed to steam?
  A: No. This is a dry environment transducer. Use with appropriate probe mounting hardware and avoid direct fluid contact.
• Q: How to verify scale factor before installation?
  A: Use a Bently Nevada TK-3 calibrator or micrometer fixture. Measure output at 0, 12.7, and 25.4 mm positions. Slope should be 0.20 V/mm ±2%.
• Q: What is the maximum cable length without signal degradation?
  A: Keep extension cable under 305 m (1000 ft) for full accuracy. Use Bently-approved coaxial cable with proper impedance.
• Q: Does this model include the spring return option?
  A: No. The 01-00 suffix indicates 01 = 25.4 mm range with 127 mm rod, 00 = without spring return. For spring return order 135613-01-01.
• Q: How to select between this and the 135613-01-01?
  A: Choose 135613-01-00 for applications requiring springless positive contact. Choose 135613-01-01 when automatic retraction is needed for mechanical clearance.
