FAQs

  • What is this 74712-06-12-04-CN?+
    The Bently Nevada 74712-06-12-04-CN is a high-temperature Seismoprobe velocity transducer designed to measure casing and structural vibration on heavy-duty rotating machinery.
  • What is the difference between the Bently Nevada 9200 and 74712?+
    The 74712 is an upgraded, high-temperature version of the standard 9200 sensor. While the 9200 is rated up to +121°C (+250°F), the 74712 safely operates up to +204°C (+400°F).
  • Does the velocity transducer require an external power supply?+
    No. The Seismoprobe is a self-powered sensor that generates its own signal based on the velocity of the machinery's vibration, significantly simplifying installation.
  • Does it require an external power source?+
    No. It features a self-powered moving-coil design that translates mechanical motion into a voltage output independently.

MORE INFORMATION

Overview Manuals Technical notes Product Applications Electrical Cable Connection

Features:

  • Measures Absolute Bearing Housing, Casing, or Structural Vibrations
  • Two-Wire System
  • Sensitivity of 20 mV/mm/s (500 mV/in/s)
Bently Nevada Seismoprobe Velocity Transducer Systemsare designed to measure absolute (relative to free space)bearing housing, casing, or structural vibration. The two-wiresystems consist of a transducer and appropriate cable.

The Seismoprobe family of velocity transducers is a two-wiredesign that uses moving-coil technology. It provides avoltage output directly proportional to the transducer'svibration velocity.

Moving-coil transducers are less sensitive to impact orimpulsive excitation than solid-state velocity transducers,which are inherently accelerometers with embeddedintegration electronics.

The 74712-06-12-04-CN 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 74712-06-12-04-CN 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 Bently Nevada 9200 and 74712 Seismoprobe Velocity Transducers are premium, industrial-grade two-wire sensors to measure absolute casing, bearing housing, or structural vibration relative to free space. They are deployed globally for the continuous machinery protection and periodic diagnostics of mid-to-low speed rotating assets where rolling-element bearings or structural configurations require casing-velocity monitoring. Common applications include older gas and steam turbines, heavy industrial fans, large pumps, and centrifugal blowers.
  • Fossil Fuel & Coal Plants:PA/FD fans & pulverizers near boilers
  • Combined-Cycle Gas Plants:Aux turbine bearings, boiler pumps & HRSG blowers
  • Hydrocracking & Distillation Units:High-temp vertical pumps for hot oil/chemicals
  • Fertilizer & Ammonia Plants:Vertical pumps & fans in high-heat steam areas
  • Steel and Metal Smelting Mills:Furnace exhaust & combustion blowers in extreme heat
  • Pulp, Paper, and Timber Mills:Drying rollers, kiln exhaust & boiler systems

Connector Alignment: The 04 option means your transducer has a side-mount connector. Carefully align the pins of your 2-socket female interconnect cable with the sensor's side plug.
Cable Selection: Because the 74712 operates in environments up to 204°C (400°F), ensure you are using a high-temperature rated, two-wire shielded cable (such as an armored stainless-steel variant) to prevent insulation melt.
Strain Relief: Secure the cable to adjacent rigid structural components using clamps within 10–15 cm (4–6 inches) of the sensor. This minimizes whip and stress on the side-mount connection block.
