Bently Nevada 177230-00-01-05 Seismic Vibration Transmitter | Loop-Powered 4-20 mA

Product Description

The 177230-00-01-05 (Part Number: 177230-00-01-05) is a high-precision seismic velocity transmitter designed by Bently Nevada for the cost-effective monitoring of general-purpose rotating machinery. This all-in-one sensor integrates a vibration transducer with advanced signal conditioning electronics to provide a standard 4 to 20 mA analog output. This signal is proportional to the overall vibration velocity, allowing for direct integration into PLCs, DCS, or SCADA systems without the need for a separate vibration monitoring rack.

Engineered with a robust 316L stainless steel housing, the 177230-00-01-05 is hermetically sealed to withstand the harsh conditions of industrial plants, including exposure to moisture and corrosive agents. The unit's piezoceramic sensing element provides exceptional stability and accuracy across its frequency range, making it a reliable solution for detecting early signs of mechanical issues such as imbalance, misalignment, or bearing degradation in pumps, motors, and fans.

Technical FAQ

What is the benefit of the -05 option in the model number?The -05 suffix specifically denotes the agency approval option. For the 177230-00-01-05, this typically refers to multiple global certifications (such as ATEX, IECEx, or CSA) for use in non-hazardous or specific hazardous areas, providing versatile deployment options for global projects.

Does this transmitter require a specialized monitor?No. Because the 177230-00-01-05 outputs a standard 4-20 mA current loop, it can be connected directly to any analog input card on a standard industrial controller. This eliminates the cost of a dedicated vibration monitoring rack.

Can the mounting thread be changed in the field?The mounting thread is determined by the hardware option (-01 indicates a 1/4-28 UNF stud). While adapters can be used, it is recommended to specify the correct mounting option at the time of order to ensure the best mechanical coupling for vibration transfer.
