Description
The Bently Nevada 74712-06-05-02-01 is a high-temperature two-wire Seismoprobe velocity transducer designed for measuring absolute (relative to free space) bearing housing, casing, or structural vibration in industrial machinery. It is the high-temperature variant of the 9200 series, qualified for continuous operation in environments from -29 °C to +204 °C (-20 °F to +400 °F).
This transducer utilizes moving-coil technology, providing a voltage output directly proportional to the transducer's vibration velocity. The two-wire design requires no external power supply, making it convenient for both continuous monitoring installations and portable measurement applications. Moving-coil transducers are inherently less sensitive to impact or impulsive excitation than solid-state velocity transducers, which are accelerometers with embedded integration electronics. This characteristic makes the 74712 suitable for applications where mechanical shocks or impulsive forces may be present.

Product Applications
Mounting Location & Orientation
Features:
- High-temperature two-wire velocity transducer
- Wide temperature range of -29°C to +204°C (-20°F to +400°F)
- Moving-coil technology
- No external power required
- Side-mounted connector configuration
Configured with the 06 operating-frequency option, the unit supports applications requiring a 10 Hz minimum operating frequency and flexible mounting orientation. The 05 mounting option incorporates a 1/2-20 UNF-3A stud without an integrated base, allowing direct installation on machinery surfaces. The 02 connector option provides a terminal block top-mount connection for secure field wiring, while the 01 approval designation indicates CSA/NRTL certification for industrial installations.
The 74712-06-05-02-01 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).

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 transducer delivers a sensitivity of 20 mV/mm/s (500 mV/in/s) with ±5% accuracy when properly terminated and oriented at the calibration angle. The frequency response extends from the minimum operating frequency of 10 Hz up to 1 kHz (60,000 cpm) with a typical +0, -3 dB roll-off. The dynamic operating range accommodates up to 2.54 mm (0.100 in) peak-to-peak displacement and 25 mm/s (1 in/s) casing vibration at 100 Hz with a 10 kΩ calibration load.

This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Placement: Mount the transducer directly onto the machine casing or bearing housing where it can best detect structural rotor vibration.
Orientation Angle: Because option 06 specifies a 0° vertical orientation, the sensor must be mounted within ±100° of true vertical to function within its calibrated accuracy. Mounting it beyond this window will compromise the internal moving-coil mechanism.
Technical notes
Bently Nevada 74712-06-05-02-01 operates over an extended temperature range of -29°C to +204°C (-20°F to +400°F), making it the high-temperature version of the Bently Nevada Seismoprobe family, specifically engineered for continuous monitoring or periodic measurements in conjunction with test or diagnostic instruments in process industries with thermal extremes.
FAQs
-
Do I need external power for the 74712?
+No. The 74712 is a two-wire system that does not require external power, making it incredibly convenient for continuous monitoring or periodic portable measurements. -
What is the maximum allowed cable length?
+You can run up to 305 meters (1,000 feet) between the Seismoprobe and your Bently Nevada monitor. Keep in mind that longer cables may cause frequency roll-off. -
How does the 74712 handle extreme environments?
+The 74712 is engineered specifically for high-temperature applications up to +204°C. Because it utilizes moving-coil technology, it is inherently less sensitive to impulsive excitation or impact shock compared to solid-state velocity transducers. -
What does the 06 mounting angle signify?
+Versatility. It means the transducer can be mounted vertically (0°) but is rated to operate properly even if tilted up to ±100° away from vertical. This essentially allows it to be oriented upside down or horizontally while maintaining its specified 10 Hz lower frequency threshold.
