The 74712-06-05-02-00 is a high-temperature two-wire Seismoprobe Velocity Transducer from Bently Nevada, designed to measure absolute (relative to free space) bearing housing, casing, or structural vibration.The 74712 is a high-temperature version of the Seismoprobe family, utilizing moving-coil technology to provide a voltage output directly proportional to the transducer's vibration velocity.

The 74712-06-05-02-00 operates continuously over a standard temperature range of −29°C to +204°C (−20°F to +400°F), enabling reliable performance in high-temperature industrial environments where conventional transducers would fail. The 74712 does not require external power, making it convenient for both continuous monitoring installations and portable measurement applications in conjunction with test or diagnostic instruments.

The 74712-06-05-02-00 Bently Nevada High-temperature Two-wireTransducer may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
Bently Nevada 74712-06-05-02-00 High-temperature Two-wireTransducer Manuals, Datasheets, Drivers, Link 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.
The 74712-06-05-02-00 configuration incorporates a 1/2-20 UNF threaded stud for direct mounting and a top-mounted connector arrangement that facilitates installation and maintenance. The sensor can be connected to Bently Nevada monitoring systems, vibration monitors, and machinery protection platforms for continuous asset condition assessment.
Frequency response extends from the minimum operating frequency of 10 Hz (600 cpm) to 1 kHz (60,000 cpm) with +0, –3 dB typical deviation. The velocity range is 25 mm/s (1 in/s) at +22°C with a 10 kΩ load. Maximum lead wire length between the transducer and the monitor is 305 metres (1,000 feet); frequency roll-off at longer lengths should be consulted in the installation manual.

Polarity: Pin A goes positive relative to Pin B when the transducer case velocity moves toward the connector.Signal Load: Requires a 10 kΩ resistive load across pins A and B.
Cable Limits: Maximum lead wire length is 305 meters (1,000 feet) between the transducer and the monitor.
Signal Converter: Can be connected to the Bently Nevada 9513 VDC (Velocity-to-Displacement Converter) if velocity-to-displacement conversion is required.

Technical notes

The 74712 is available with comprehensive hazardous area approvals including cNRTLus, ATEX, and IECEx certifications for installation in potentially explosive atmospheres. The 74712 meets Class I, Division 1, Groups A, B, C and D; Class II, Groups E, F and G; and Class III requirements, as well as Class I, Zone 2 with Ex nA IIC T6 Gc and Ex ec IIC T6 Gc ratings at ambient temperatures from −20°C to +40°C. The 74712 also complies with FCC Part 15 rules, EMC Directive 2014/30/EU (EN 61326-1), and RoHS Directive 2011/65/EU, ensuring electromagnetic compatibility and environmental compliance for industrial use.
