The Bently Nevada™ Seismoprobe velocity sensor system is designed to measure absolute vibration (relative to free space) in bearing housings, shells, or structures. This two-wire system consists of a sensor and a corresponding cable. The Seismoprobe series of velocity sensors features a moving-coil two-wire design, providing a voltage output proportional to the sensor's vibration velocity.
Compared to solid-state velocity sensors (essentially accelerometers with embedded integrated electronics), moving-coil sensors are less sensitive to shock or pulse excitation. This low sensitivity to shock or pulse excitation makes them ideal for certain applications. Because they require no external power supply, they are suitable for portable measurement applications.
The 74712-06-12-04-CN Bently Nevada Two-wire Transducer may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

It is typically integrated into large monitoring systems, such as the Bently Nevada 3500 or 3300 series, to provide real-time diagnostic data for predictive maintenance. Because it requires no external power supply, it is also well-suited for portable field diagnostics.
This specialized sensor is suitable for heavy industrial equipment operating in harsh, high-temperature environments:
Gas turbines and steam turbines: Monitor structural vibration and bearing housing health;
Large pumps and compressors: Detect imbalances, misalignments, or mechanical loosening;
Electric motors and generators: Continuously track vibration to prevent catastrophic failures;
Water turbines: Provide stable, low-frequency casing monitoring.
