37439-01 Bently Nevada Seismic Transmitter – PLC Spare Hub

37439-01 – Bently Nevada Seismic Transmitter

37439-01 is a Seismic Transmitter from Bently Nevada. Made in U.S.A. Designed for use with serial numbers NOT preceded with “G”. Features a ¼-28 to ¼-28 mounting base that effectively reduces base strain sensitivity.

Technical Highlights

• Manufacturer: Bently Nevada (GE Measurement & Control).
• Product Type: Seismic Transmitter.
• Mounting Base: ¼-28 to ¼-28 thread.
• Key Feature: Reduces base strain sensitivity for accurate vibration measurement.
• Serial Number Restriction: For units NOT preceded with letter “G”.
• Origin: Made in U.S.A.

Installation & Compatibility

• Mounts directly via ¼-28 threaded base – standard for seismic probes.
• Compatible with Bently Nevada monitoring systems (e.g., 3500, 3300 series).
• Verify serial number prefix before installation – unit is not for “G” series.
• Use with appropriate cable and connector for signal integrity.

Typical Applications & Compatible Equipment

Frequently Asked Questions (FAQ) – Expert Advice

• Q: How do I know if this transmitter fits my existing mount?
  The 37439-01 uses a ¼-28 thread. Measure your current mount – if it matches, it’s a direct replacement. We can help verify with your serial number.
• Q: What does “reduces base strain sensitivity” mean practically?
  It minimizes measurement errors caused by mounting surface deformation. This is critical for accurate vibration data – we recommend proper torque (consult our team).
• Q: Can I use this with a 3500 rack?
  Yes, it is fully compatible with Bently Nevada 3500 systems. Ensure your rack’s input card matches the transmitter output (we can check card compatibility).
• Q: Why can’t I use it with “G” serial number units?
  “G” prefix units use a different mounting interface. If you have a “G” unit, contact us – we can source the correct version.
• Q: What is the typical lifespan of this transmitter?
  In normal operation, 5–10 years. Replacement is recommended if output drifts – we offer testing services to verify your existing unit.
