Features:
- Self-generating signal: The moving-coil element produces a velocity output without external sensor power.
- High-temperature construction: The 74712 family is specified for operation from −29°C to +204°C.
- Decoded configuration: Codes 01-10-02-00 define orientation, frequency, mounting base, connector position, and approval option.
74712-01-10-02-00 belongs to the Bently Nevada 74712 Seismoprobe family for absolute casing-vibration measurement.
Its published sensitivity is 20 mV/mm/s, with a 25 mm/s velocity range at 100 Hz when loaded by 10 kΩ.
The complete model matters because mechanical orientation, stud thread, connector location, and approval option are all encoded in the suffix.
Apter Power supports 74712-01-10-02-00 enquiries with model decoding, sourcing assistance, technical-document coordination, and installation-record review.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- 01 option: 0° ±2.5° mounting angle with 4.5 Hz minimum operating frequency.
- 10 option: Circular mounting base with an M10x1 stud.
- 02-00 options: Top-mount connector and no agency approvals.
- Sensitivity: 20 mV/mm/s with the published tolerance for the 74712 construction.
- Velocity range: 25 mm/s at 100 Hz with a 10 kΩ load and casing temperature near +22°C.
- Electrical character: Approximately 1.25 kΩ coil resistance and 125 mH typical locked-coil inductance.
- Mechanical fit: Preserve the 0° orientation, circular base, and M10x1 stud specified by the ordering code.
- Connector fit: Code 02 places the connector on the top, so routing and clearance must match the installed arrangement.
- Approval scope: Code 00 carries no agency approval; do not transfer certifications from a different 74712 option.
- Casing vibration: The Seismoprobe measures absolute bearing-housing or machine-casing velocity where its frequency range is suitable.
- High-temperature machinery: The 74712 construction supports locations that exceed the temperature capability of standard velocity transducers.
- Legacy maintenance: The full option code supports replacement review without assuming that another 9200 or 74712 configuration is interchangeable.
