Product Description

Description

The Bently Nevada 177230-01-01-05 is a loop-powered seismic transmitter designed for machinery condition monitoring. It integrates directly into programmable logic controllers (PLCs), DCS, and SCADA systems that provide internal loop power. The 177230-01-01-05 processes vibration measurements and outputs a primary 4 to 20 mA current loop representing velocity vibration, along with a secondary raw dynamic voltage output representing acceleration for detailed signal analysis.

Features

Interfaces directly with PLCs, DCS, and SCADA control systems.
Provides a primary 4 to 20 mA loop-powered velocity output and a secondary raw dynamic voltage output.
Requires no field configuration or adjustments.
Features a hermetically sealed 316L stainless steel case for demanding environments.
Includes self-test capabilities and a protected interface.

Applications

Machinery asset condition monitoring
Overall plant vibration measurement
Balance-of-plant rotating machinery protection
Integration into PLC, DCS, and SCADA control loops

Installation Guidelines

Mounting Method: Mount directly to the machine surface using the provided stud adapters and torque to 4 to 7 N-m.
Magnetic Base Precaution: If using a magnetic base, roll the base onto the machine surface. Avoid snapping the unit onto the machine, as sudden impact can generate large voltage spikes that may damage internal electronics.
Grounding and Signal Isolation: Ensure the dynamic signal return (Pin B) is isolated from external grounds. Grounding this terminal shorts the 4 to 20 mA current loop, resulting in signal loss.

FAQ

What power supply is required to operate the device?

The device operates on a 12 to 30 Vdc loop power excitation voltage, current limited to 40 mA, typically supplied directly by host PLCs or DCS controllers.

What outputs are provided by the unit?

The device provides a primary 4 to 20 mA loop-powered velocity output on Pin A and a secondary unbuffered dynamic acceleration voltage output on Pin C.

What mounting precaution should be followed when using a magnetic base?

The device must be rolled onto the machine surface rather than snapped into place, preventing mechanical shocks that can produce high voltage spikes and damage internal electronics.
