Bently Nevada 177230-01-01-RU Loop‑powered Seismic Transmitter

FAQ

Q1: What is the 177230‑01‑01‑RU used for?
A1: It is a seismic transmitter used to convert vibration (velocity) into a 4‑20 mA signal for use in control, monitoring, or PLC/DCS systems.

Q2: What does the “RU” suffix imply?
A2: The “RU” typically denotes a regional or regulatory variant (e.g. Russian or custom approval), with the functionality otherwise matching standard 177230 transmitters.

Q3: What is the velocity measurement range?
A3: The baseline range is 0 to 12.7 mm/s RMS; optional ranges up to 25.4 mm/s or 50.8 mm/s are configurable.

Q4: What output signals are available?
A4: The device outputs a 4–20 mA current loop signal for velocity. It also provides an unbuffered voltage signal for acceleration via a third pin.

Q5: What are the physical size and weight?
A5: It is about 25.4 mm in diameter, 66 mm in height, and weighs approximately 0.131 kg.

Q6: What are the supply requirements?
A6: It requires 12 to 30 V DC input, with current limited typically to 40 mA.

Q7: What environmental conditions can it tolerate?
A7: It operates from –40 °C to +85 °C and supports full humidity (non‑submerged) operation.

Q8: How does it detect or manage faults?
A8: The module includes self-test and protected interface features; the dynamic signal line must remain isolated, or the loop could be compromised.
