Frequently Asked Questions (FAQ)

• Q: Is this transmitter brand new and original?
  A: Yes, we provide 100% new original Bently Nevada 177230-01-01-05 units. No used or refurbished parts.
• Q: What power supply works with this seismic transmitter?
  A: It requires 12 to 30 Vdc with current limited to 40 mA. Most PLCs and DCS internal supplies work fine (30-35 mA typical).
• Q: Can I use this transmitter in hazardous environments?
  A: Yes, approval code 05 includes CSA/NRTL/C and ATEX/IECEx certifications for safe use.
• Q: How do I interpret the 4-20 mA output?
  A: 4 mA equals 0.0 mm/s; 20 mA equals the full scale 25.4 mm/s (±10% tolerance). The signal represents RMS vibration levels.
• Q: What is the frequency response range?
  A: The unit measures 10 Hz to 1 kHz (600 to 60 kcpm) with ±10% accuracy.
• Q: Does the device include a dynamic signal output?
  A: Yes, Pin C provides an unbuffered dynamic acceleration signal referenced to Pin B.
