Official product overview

High-temperature two-wire Seismoprobe velocity transducer

Bently Nevada 74712-01-11-02-00 is the high-temperature 74712 Seismoprobe configuration with 0-degree mounting orientation, 4.5 Hz minimum operating frequency, an isolated circular M10 x 1 mounting base, a top-mount connector and the 00 No Approvals option.

Quotation status: Current availability, condition and commercial terms are subject to verification for the exact part number.

Applications

System role

Machine-casing velocity measurement at elevated temperature

Measure absolute bearing-housing, casing or structural vibration in velocity units.
Use where the 74712 high-temperature range is required and the mounting orientation matches the 0-degree option.
Connect to compatible Bently Nevada monitors or diagnostic instruments through the correct interconnection cable.
Use the isolated M10 x 1 base where the verified mounting arrangement requires electrical isolation.

Selection note: Do not apply the unit at an unverified angle. Seismoprobe transducers are specified for a defined mounting orientation.

Construction

Construction and interfaces

Self-generating two-wire velocity transducer

The 74712 uses the Seismoprobe moving-coil principle and provides a velocity-proportional signal across its two terminals. This code uses an isolated circular M10 x 1 base and top-mounted connector; a suitable interconnection cable is separate.

Interface check: Confirm monitor input, cable temperature rating, connector type, polarity and allowable lead length before installation.

Installation

Installation discipline

Orientation is part of the calibration

Mechanical direction, base condition and cable choice must match the exact order code.

Mounting angleInstall at the specified 0-degree orientation within +/-2.5 degrees.	Base torqueM10 x 1 base option: 5.6 N m (50 in-lb).	SurfaceUse a clean, rigid mounting surface prepared to the official instructions.
CableSelect a compatible high-temperature or standard interconnection cable for the environment.	PolarityPin A goes positive relative to pin B for motion toward the connector.	MonitorVerify the connected monitor and frequency response requirements.

Before energizing or operating: The top-mount connector must be protected by the correct mating cable and installation practice; integral cable is not available for the 74712.

Environment

Protection and environment

Environment

The 74712 extends Seismoprobe operation to +204 C, while this exact option remains No Approvals.

Operating / storage temperature	-29 to +204 C (-20 to +400 F)
Relative humidity	To 95%, noncondensing
Environment	Dust and moisture resistant
Maximum altitude	2000 m (6561 ft)
Approval option	00 No Approvals; safe-area use
High-temperature cable	Select cable type and temperature rating separately

Compliance note: If hazardous-area approval is required, do not use option 00 as an assumption. Select and verify an approved configuration and certificate package.

FAQ

Short answers

FAQ

Orientation, cabling and safe-area status are the main compatibility checks.

Is an integral cable included?	No. Integral cable is not available with the 74712; choose a compatible interconnection cable separately.
Can it be mounted horizontally?	This exact option is calibrated for 0 degrees +/-2.5 degrees; another orientation requires a different code.
Does 00 include hazardous-area approval?	No. Option 00 is the No Approvals configuration.
Stock status	Confirm before quotation for the exact part number, quantity and destination.
Condition	New, used or refurbished status is stated in the written quotation.
Current photos	Overall-unit and nameplate photos are available on request for the quoted unit.
Test statement	Available on request and subject to the agreed inspection or test scope.
Warranty	Confirmed in the formal quotation.
Dispatch time	Confirmed after stock, destination and order approval are verified.
Payment methods	Available on request in the formal quotation.
Quote response	Subject to request completeness and verification.
Transaction trust	Company details, quotation, invoice and beneficiary information are available for review before payment.
Part-specific answer	Confirm the mating cable, mounting orientation and safe-area requirement for the quoted unit.
