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
