Features:
- Low-frequency sensitivity down to 90 rpm enables accurate vibration measurement on slow-speed cooling tower and heat-exchanger fans.
- Multiple hazardous area approvals (CSA/NRTL/C Division 1, ATEX/IECEx/CSA Zone 0/1) allow deployment in classified locations worldwide.
- MIL-C-5015 connection interface with stud mounting adapter (3/8-24 to 1/2-20) provides rugged, weather-resistant installation.
The 190501-02-00-05 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). This capability enables early detection of developing faults such as fan imbalance, bearing wear, and speed reducer issues that would otherwise go unnoticed until catastrophic failure occurs. For facilities relying on cooling assets for process temperature control, this early warning translates directly to reduced downtime and avoided production losses.
The 190501-02-00-05 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. For multinational organizations, this eliminates the need to stock region-specific variants and simplifies compliance documentation. The rugged construction and weather-resistant MIL-C-5015 connector ensure reliable operation even in outdoor, moisture-prone environments typical of cooling tower installations.
Beyond measuring the fundamental fan vibration frequencies, the 190501-02-00-05 captures the higher-frequency vibrations generated by the fan motor and speed reducer. This provides a comprehensive picture of the entire drive train, from the motor through the gearbox to the fan blades. The stud mounting adapter (3/8-24 to 1/2-20) simplifies installation on motor frames, fan housings, and speed reducer cases, while the MIL-C-5015 interface ensures a secure, weather-resistant connection. For maintenance teams, this means one sensor can monitor multiple failure modes across the entire cooling system, streamlining both installation and ongoing vibration analysis.
The 190501-02-00-05 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).
