Function and Working Principle
The 190501-09-99 Velomitor CT continuously measures vibration velocity generated by rotating machinery and converts this mechanical movement into a proportional electrical signal.
Main Functions
- Continuous vibration monitoring
- Machinery condition assessment
- Early fault detection
- Predictive maintenance support
- Asset protection and reliability improvement
Working Principle
The sensor contains an integrated piezoelectric sensing element that responds to machine vibration. As vibration occurs, the internal element generates an electrical output proportional to vibration velocity. This signal is transmitted to a monitoring system where vibration trends, alarm levels, and equipment conditions can be analyzed.
Because the Velomitor CT is optimized for low-frequency operation, it is particularly effective for machinery operating at relatively low rotational speeds where standard accelerometers may not provide sufficient measurement accuracy.
Role in Machinery Protection Systems
In industrial condition monitoring systems, the 190501-09-99 performs several important functions:
- Detects developing mechanical faults
- Monitors equipment health continuously
- Supports predictive maintenance programs
- Minimizes unexpected shutdowns
- Extends machinery service life
- Reduces maintenance costs
The sensor is commonly incorporated into plant-wide machinery monitoring strategies where reliability and uptime are critical.
Industrial Applications
The 190501-09-99 is frequently installed in:
- Cooling tower fan assemblies
- Air-cooled heat exchangers
- Industrial ventilation systems
- Power generation facilities
- Petrochemical plants
- Water treatment installations
- Mining operations
- Process manufacturing equipment
Its low-frequency measurement capability makes it particularly valuable for large, slow-speed rotating machinery.
Installation and System Integration
For optimum performance, the sensor should be installed according to recommended vibration monitoring practices:
- Mount directly to the bearing housing or machine casing
- Use approved metric plate stud mounting hardware
- Ensure rigid mechanical contact with the monitored surface
- Follow proper grounding procedures
- Route cables away from electrical interference sources
- Verify secure connector installation before commissioning
Proper installation helps maximize measurement accuracy and long-term reliability.
