74712-03-11-02-00 is a high-temperature two-wire Seismoprobe velocity transducer configured for 90° ±2.5° horizontal mounting. It measures absolute bearing-housing, casing or structural vibration using moving-coil technology.
The complete order code specifies mounting-angle option 03, an isolated circular M10 x 1 mounting base, a top-mounted connector and no hazardous-area approval option. Its velocity output sensitivity is 20 mV/mm/s, with a 4.5 Hz minimum operating frequency for this orientation option.
The transducer requires no external power and provides an output voltage directly proportional to vibration velocity. Install it on a rigid bearing housing or machine casing, preserve the specified orientation and connect it to compatible monitoring or diagnostic instrumentation with the appropriate high-temperature cable.
Bently Nevada 74712-03-11-02-00 is a self-generating two-wire moving-coil velocity transducer for absolute vibration measurement on machine casings and bearing housings. Its high-temperature construction supports operation from -29 to +204 °C.
This configuration is calibrated for 90° ±2.5° horizontal mounting and uses an isolated circular M10 x 1 base with a top-mounted connector. Its nominal output is 20 mV/mm/s and the orientation option has a 4.5 Hz minimum operating frequency.
The transducer generates a voltage proportional to casing vibration velocity and does not require an external excitation supply.
Retain the complete order code because mounting orientation, base, connector and approval positions affect the installed configuration.
Incorrect mounting orientation or a flexible mounting surface can reduce amplitude and frequency response or create signals that do not represent machine vibration.
