Product Description:

The Bently Nevada 177230-01-02-CN is a loop-powered Seismic Vibration Transmitter bundled with the 16710-16 Interconnect Cable. It is purpose-built to continuously track the structural health of general-purpose rotating industrial machinery. The 177230 Seismic Transmitter is a simple, loop-powered device that can be quickly and easily installed. It can be integrated into your programmable logic controller (PLC) or controls system linked to a plant asset condition monitoring solution. Its simple design reduces training, maintenance, and service costs. The transducer helps you better manage downtime, optimize maintenance planning, and avoid unforeseen catastrophic failures of machinery assets. The 177230 Seismic Transmitter incorporates robust CM design for reliability and implements an industry-standard 4 to 20 mA loop-powered transmitter.

Frequently Asked Questions (FAQ)

Q:How is the transmitter powered?

A:It is a 4-20 mA loop-powered device. It utilizes the same two wires for power and signal telemetry, typically drawing from the internal current-limited power supplies (30 mA to 35 mA range) of your PLC or DCS.
Q:What is the most critical wiring mistake to avoid?
A:Pin B must remain isolated from any grounding source. If the dynamic signal negative (Pin B) accidentally shorts to the machine or local electrical earth ground, the 4-20 mA loop will short-circuit, resulting in an immediate zero-signal output.

Q:How should the transmitter be mechanically mounted?
A:It should be mounted flush against the machine housing via a standard 1/4-28 UNF, M6, or M8 stud. Ensure it is torqued correctly; over-tightening will fracture the internal piezo-crystals, while under-tightening causes severe high-frequency signal attenuation.
