Bently Nevada 177230-01-01-00 Loop‑powered Seismic Transmitter

FAQ

Q1: What is the purpose of the 177230‑01‑01‑00 transmitter?
A1: It is a seismic transmitter that converts vibration (velocity) from rotating machinery into a 4–20 mA signal for use in PLC, DCS or SCADA systems.

Q2: What measurement ranges are supported?
A2: The standard range is 0 to 12.7 mm/s RMS, with optional ranges up to 25.4 mm/s or 50.8 mm/s depending on variant.

Q3: What is the frequency response of the device?
A3: It operates across 10 Hz to 1 kHz with ±10 % accuracy over that band.

Q4: What output signals does it provide?
A4: It provides a 4–20 mA loop output for velocity plus an unbuffered voltage output for acceleration (via Pin C).

Q5: What physical size and weight does the transmitter have?
A5: It is 25.4 mm in diameter, 66.0 mm tall, and weighs approximately 0.131 kg.

Q6: What is the required supply voltage?
A6: The device requires 12 to 30 V DC, with current limited to 40 mA max.

Q7: How does the transmitter handle signal faults or overloads?
A7: Its built-in isolation and protected interface help prevent ground faults; the dynamic signal (Pin C) must remain isolated from loop return or it can short.

Q8: What environmental limits and certifications apply?
A8: It operates from –40 °C to +85 °C, tolerates 100 % humidity (non‑submerged), and is built for industrial use with standard isolation and reliability features.

If you need the precise variant’s calibration, hazardous area certification, or wiring details, I can extract those from the datasheet for you.
