Valve Alert and on-line monitoring

What is Valvealert™
Valvealert™ is a technology that provides automatic detection and alerting
to anomalies with the operation of reciprocating compressors.
Valvealert™ records an acoustic emission (AE) and temperature fingerprint
for the operation of each valve (baseline). Data is analyzed against the
baseline to determine the anomalies with the operation of the compressor.
Valvealert™ provides detection of:
  • Leaking Valves
  • Stiff /Weak springs
  • Slamming
  • Valve Flutter
  • Late and early valve opening and closing events
  • Key benefits of Valvealert™
  • Valvealert™ is intrinsically safe
  • Valvealert™ is non-intrusive
  • No drilling or tapping of the cylinders
  • Simple and fast data collection
  • Automatic analysis of the data
  • Automatic triggering of alerts
  • Simple graphical status display
 Valvealert™ Platforms
 Valvealert™ is available in two main options:
  • VA2 handheld portable data collector
  • Mentor™ permanent on-line monitoring system
 Both options are available as standalone or networked systems:
  • Valvealert™ platforms can be mixed
  • Monitor non-critical machines using VA2 portable data collectors
  • Monitor critical machines using the Mentor™ system
  • Valvealert™ server service provides a central control point for information.
VA2 Handheld Portable Data Collector
The handheld data collector records acoustic emission data and
temperature. A sensor from the handheld unit is attached to a quick
release connector bonded to the valve cover. Once the data is collected
and stored on the VA2 unit, it is uploaded to a PC or laptop where the
data is automatically analyzed by the Valvealert™ software. Making this
a versatile way of monitoring compressor valves in all applications.
 
Mentor™ On-Line Monitoring System
This option is more permanent providing a complete condition based
maintenance and optional performance analysis for reciprocating
machinery, that encompasses; machine protection, condition monitoring
and performance monitoring.
 
Mentor™ on-line monitoring and diagnostic system records and analyzes
machine data in real-time, using Valvealert™ pattern recognition technology;
making condition, risk assessments, fault diagnosis, maintenance and
operational information, and alert generation available 24 hours a day.
 
The Mentor™ system provides a portal for continually acquiring condition
data such as valve acoustic emissions and temperature. Further access to the
information from plant databases can be made available over the internet.
Additionally the system provides easy scalability and integration of different
technologies.
 
Valvealert™ Software
Data is analyzed using the sophisticated algorithms embedded within the
software, with the results of the analysis presented to the user through
simple graphic displays. In addition the Valvealert™ software provides a full
complement of trending and diagnostic features. The usability of the
Valvealert™ software means an accurate assessment of valve performance
can be established without the need for specialist training.
