Thermocouples

• Isolated Omega Type-E T/C as used on vessel, ~$30 ea• In-house signal conditioning equipment• Instrument one 3-coil set:

• Winding pack near cooling inlet/outlet• 2 gages x 2 wp x 2 plcs x 3 coils = 24

• Winding pack near leads• 2 gages x 2 wp x 3 coils = 12

• Winding forms• 6 gage x 3 coils = 18

• Total no. gages = 54• Instrument winding pack only for remaining coils:

• 36 gages x 15 coils = 540• Total no. gages = 594• Cost = $18k
