More Information

Overview Manuals Ordering Code Signal and Range Installation Boundary Product Applications

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.

  • 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.
Description
For high-temperature casing measurements, the Bently Nevada 74712-01-10-02-00 is a two-wire Seismoprobe velocity transducer for absolute vibration at a bearing housing, machine casing, or supporting structure. The complete order string identifies the supplied configuration and should remain attached to the installed asset record.

Using a self-generating moving-coil sensing principle, 74712-01-10-02-00 produces an electrical output that follows vibration velocity without a separate excitation supply. This construction is useful where casing vibration and transient mechanical conditions must be evaluated with the matching monitor input and field cable.

Before replacement work begins, 74712-01-10-02-00 records should preserve mounting orientation, cable assembly, connector condition, sensitivity, temperature boundary, and channel configuration. A visually similar 74712 family transducer is not automatically interchangeable because suffix changes can alter the ordered assembly.

Technical notes
74712-01-10-02-00 is a self-generating moving-coil velocity transducer intended for absolute bearing-housing, casing, or structural vibration measurements. Preserve the full order string, mounting orientation, cable assembly, connector, temperature boundary, sensitivity, and monitor input configuration. A similar 74712 family sensor should not be treated as interchangeable without checking every coded option.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What does 74712-01-10-02-00 measure?
It measures absolute vibration velocity at a bearing housing, casing, or structure relative to free space.
Does 74712-01-10-02-00 require external excitation power?
The moving-coil transducer is self-generating, but its signal must still be connected to a compatible vibration-monitor input.
Why must the full 74712-01-10-02-00 order string be retained?
The complete string distinguishes the ordered transducer configuration; the family number alone is insufficient for replacement selection.
Can another 74712 family transducer replace 74712-01-10-02-00 directly?
Not automatically. Compare the complete order code, sensitivity, mounting, cable, connector, temperature boundary, and monitor requirements.
What should be recorded before removing 74712-01-10-02-00?
Record the full model, installed orientation, mounting hardware, cable assembly, connector, channel sensitivity, monitor input, and alarm configuration.
What should be checked after installing 74712-01-10-02-00?
Verify mounting security, cable routing, connector condition, shield and grounding practice, configured sensitivity, signal polarity, and baseline vibration response.
