Bently Nevada 177230-00-01-CN Seismic Transmitter

The Bently Nevada 177230-00-01-CN Seismic Transmitter is a high-performance vibration monitoring device designed for direct seismic measurements on rotating and reciprocating machinery. Unlike proximity probes that measure shaft displacement, this seismic transmitter directly detects casing vibration, making it particularly valuable for equipment where shaft access is limited or impractical.

Part of Bently Nevada’s trusted vibration monitoring portfolio, the 177230-00-01-CN delivers an industry-standard 4–20 mA output signal proportional to the measured vibration level. This allows seamless integration with DCS, PLC, and machinery protection systems without the need for additional signal converters.

The transmitter is widely deployed in industrial environments such as power generation, petrochemicals, pulp & paper, and oil & gas, providing accurate vibration data for early fault detection, condition monitoring, and predictive maintenance. With its rugged design, high measurement accuracy, and reliability, it ensures long-term stability in harsh operating conditions.
