Install miniature sensors in or beneath the babbitt layer of bearing shoes. They monitor metal temperature — the most reliable indicator of bearing condition — to give early warning of oil film breakdown. Machines can then be shut down and the problem corrected before catastrophic failure occurs. While no larger than many bare ceramic elements, these RTDs have metal cases and insulated leads to withstand rough handling and harsh environments. They are easy to install in drilled holes for general purpose sensing.
-50 to 260°C (-58 to 500°F)
Tin plated copper alloy. Models S12414, S13282 and S101910: Stainless steel
Stranded copper with PTFE insulation; stainless steel overbraid optional (one sleeve covers all leads). Polyimide insulation available on selected models (See specification and order options).
3.0 seconds (case style A) to 1.5 seconds (case style D), typical value in moving water
10 megohms min. at 100 VDC, leads to case
Factory applied babbitt tip, available on case style A or B, reduces the danger of overheating the sensor when installed in babbitt layer
