Features:
- Low-frequency sensitivity down to 90 rpm enables accurate vibration measurement on slow-speed cooling tower and heat-exchanger fans.
- No integral stud mounting allows flexible installation using user-supplied methods such as adhesive, clamps, or custom brackets for retrofit applications.
- Multiple hazardous area approvals (CSA/NRTL/C Division 1, ATEX/IECEx/CSA Zone 0/1) allow deployment in classified locations worldwide.
The 190501-00-00-04 is specifically engineered to overcome the limitations of standard velocity sensors at low rotational speeds. While conventional sensors lose sensitivity below 600 rpm, this transducer maintains accurate measurements down to 90 rpm, covering the typical operating range of cooling tower and air-cooled heat-exchanger fans (100 to 300 rpm).
Unlike models with integral stud mounting, the 190501-00-00-04 allows users to supply their own mounting method. This flexibility is particularly valuable in retrofit applications where existing mounting points do not match standard stud patterns, or on non-metallic surfaces where drilling may be impractical.
The 190501-00-00-04 carries multiple hazardous area certifications, including CSA/NRTL/C for Class I, Division 1 locations and ATEX/IECEx/CSA for Class I, Zone 0/1 environments. These approvals allow the same transducer to be installed in refineries, chemical plants, offshore platforms, and other classified locations across North America, Europe, and international markets.
The 190501-00-00-04 Bently Nevada Velomitor CT Velocity Transducer may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Cooling Towers and Air Coolers (ACC): Monitors the overall vibration of large fans, gearboxes, and drive shafts.
- Low-Speed Rotating Machinery: Suitable for equipment with speeds down to 90 rpm, capturing low-frequency energy generated by imbalance, misalignment, or gear wear.
- Casing Vibration Measurement: Measures the velocity of machine bearing housings or casings to assess structural fatigue and mechanical health.
- Explosion-proof Approvals: -04 typically corresponds to a combination of multi-national certifications (such as ATEX, IECEx, CSA, NEPSI), allowing installation in hazardous areas such as Zone 0/1 or Class I, Div 1.
- Protection Rating: The enclosure reaches IP67 (or higher), providing resistance to 100% humidity and condensation, suitable for outdoor rainy or spray environments.
- Electromagnetic Compatibility (EMC): Complies with CE standards, possessing extremely strong resistance to electromagnetic interference, preventing false alarms caused by industrial electrical noise.
- System Compatibility: Fully compatible with 3500/70M (reciprocating/speed monitor) or 3500/72M (pole distance monitor) modules.
- Distributed System: Connects to ADAPT 3701 or Distributed vB3 monitoring platform.
- Wiring and Transmission: Uses 2-core shielded twisted-pair cable for connection, supporting long-distance transmission (up to approximately 300 meters) with extremely low signal attenuation. Compatible with standard 2-core MIL-compliant cables (such as the 16710 series).
