Temperature Detectors for Moving Bearings
Typical applications
• Accurate and reliable in engines used for gas
compression, power generation, pipeline,
marine and general industrial service
• Monitors bearings, shafts and other moving
parts for unsafe high temperature levels
• Responds to increased bearing temperatures
caused by:
- Tight, worn or out-of-round bearings
- Cracked or broken shafts
- Power or compressor cylinder overload
- Lack of lubrication fluid
- Tight packing glands
- Torsional vibration
- Mis-alignment
- Other sources of temperature rise
Key features and benefits
• Provides early warning of problems - avoids
high cost bearing failures
• Use with oil, air or gas
• Instant response to excessive bearing
temperatures
• Compact design - easy, low cost installation
• Minimal maintenance - low cost of ownership
