      Overview Manuals Common Applications Product Precautions
      Bently Nevada 190501-09-00-04 is a Velomitor CT transducer that measures low-frequency casing-vibration velocity on cooling-tower and air-cooled heat-exchanger fan assemblies.
      • Plate-stud execution for the documented fan-machine mounting point
      • Two-pin MIL-C-5015 connection for the matched monitoring cable
      • Casing vibration velocity measurement on fan-bearing housings
      • Low-frequency response suited to the documented fan application

      Use the selected bearing housing or casing point only when it transmits the rotor vibration of interest. Preserve the installed cable and monitoring-channel arrangement.

      Important Notice: Verify 190501-09-00-04, the 09 mounting stud, 00 connector, 04 approval execution, sensor polarity and accepted channel response before release.

      These documents serve different purposes: the first organizes exact transducer data and order-code options; the second covers installation readiness, mounting, connection and controlled channel acceptance.

      Cooling tower fan assembliesFollow low-frequency casing vibration on a fan assembly at or above 90 rpm when the selected point transmits rotor motion.
      Air-cooled heat exchangersMonitor vibration velocity on the fan-bearing housing or casing of an air-cooled exchanger.
      Fan-motor condition checksObserve vibration-frequency components generated by the fan motor at the documented casing point.
      Speed-reducer condition checksObserve reducer-related vibration components transmitted into the selected bearing housing or casing.
      Read the applicable Bently Nevada 190501 datasheet and site installation instructions before work. Verify 190501-09-00-04, its mounting point and monitoring channel before isolation or commissioning.
      1
      Record the complete 190501-09-00-04 marking, installed casing point and monitored fan train.
      2
      Place the fan machine and affected protection channel in the approved maintenance state.
      3
      Confirm the 09 plate stud matches the 3/8-24 transducer side and 1/4 NPT machine interface.
      4
      Confirm the 00 MIL-C-5015 cable, two-pin assignment and intended shielded-cable route.
      5
      Secure the mount at 4.5 ±0.6 N m and avoid cable strain at the connector.
      6
      Check pin-A-to-pin-B output bias against the 10.1 Vdc ±1.0 Vdc specification.
      7
      Review the site certification conditions associated with approval option 04.
      8
      Run a controlled response check and retain the accepted fan-vibration trend.

      Technical notes

      Technical notes

      The Velomitor CT transducer is intended for machines operating at or above 90 rpm, with 100–300 rpm typical. Its sensitivity is 3.94 mV/mm/s (100 mV/in/s) ±5%; response is 3–900 Hz within ±1 dB and 1.5 Hz–1 kHz within ±3 dB. Mount on the bearing housing or machine casing, use the documented plate stud and compatible wiring, and confirm response after installation.

      FAQS

      • What does Bently Nevada 190501-09-00-04 measure on a cooling-tower fan?
        It measures velocity of casing vibration at its mounting point, allowing a monitoring system to follow the low-frequency vibration of the fan assembly.
      • Which mounting stud is included with 190501-09-00-04?
        Option 09 specifies a plate stud with 3/8-24 connection on the transducer side and 1/4 NPT on the machine side.
      • What cable interface must mate with 190501-09-00-04?
        Connection option 00 uses the MIL-C-5015 interface; select a compatible two-socket cable connector and verify the installed pinout.
      • What low-frequency range can 190501-09-00-04 monitor?
        The transducer response is 1.5 Hz to 1 kHz within ±3 dB; from 3 to 900 Hz it is within ±1 dB.
      • How is the output of 190501-09-00-04 scaled?
        Its nominal sensitivity is 3.94 mV/mm/s (100 mV/in/s), with a ±5% tolerance under the stated reference conditions.
      • Where should 190501-09-00-04 be installed on the machine?
        Mount it on the bearing housing or machine casing at a location that transmits the vibration of interest; poor mounting can distort the measured response.
      • What does the final 04 in 190501-09-00-04 represent?
        It is the agency-approval ordering option. The datasheet groups options 01 through 04 under CSA/NRTL/C and ATEX/IECEx/CSA approvals; the installation must match the applicable certification conditions.
      • What should be checked after replacing 190501-09-00-04?
        Confirm the mounting torque and stud, connector and polarity, bias voltage, and a controlled vibration-response test before returning the monitored machine to service.
