In any cases it always best to get the original equipment part number for the sensor or seal. We have a very strong cross reference database for Siemens and GE turbines.

5. Sealing Products Offered for use on Turbines
All Seal fittings are used on turbines, but the most popular ones are:
BSWS seals Catalog 5001D Pages 68 and 69.
Split seals. Mostly used to seal vibration and pulsation sensors.

6. Types of Power Plants
Fossil – Steam Power Plants. Coal burning with boilers and steam turbines.
Simple Cycle Gas Plant.

14. How a Gas Turbine Works The Air is then compressed by
Passing through many stages
Compression reaching
Temperatures of 450C.

Norte-I Durango; SGT (Siemens)
La Caridad; SGT6-5000F (Siemens) NEW Site!
Products we offer
Blade Path Sensors
Disc Cavity Sensors
Flashback Sensors
Exhaust Rakes

30. Siemens Westinghouse Turbines
The Westinghouse W501 and the Siemens SGT are basically the same turbine. The SGT6 is designation is the re-badging when Siemens bought out Westinghouse.
Because of relationship with Conax selling OEM parts to Siemens, parts for Siemens turbines have to be processed through Pinnacle Parts and Service Corp.
Pinnacle is unknown to Siemens therefore is a good shield.

31. Siemens Blade Path Sensors
The base Siemens P/N is 897C or 897C for the replacement element. There are 16 Blade path sensors per turbine.
The Conax price and availability is better than that from Siemens direct and other sensor manufacturers are limited. One competitor, LPG may be out of business.
We do not have a product bulletin for these sensors.

32. Siemens Blade Path Sensors

33. Siemens Disc Cavity Sensors
The base Siemens P/N is 7863D60xxx or 7863D61xxx for the replacement element. The Disc Cavity sensors measure temperature at rows 2,3, & 4 totaling 6 sensors per turbine.
The Conax price and availability is better than that from Siemens direct and other sensor manufacturers are limited. One competitor, LPG may be out of business.
We do not have a product bulletin for these sensors.

34. Siemens Disc Cavity Sensors

35. Siemens Flashback Sensors
The base Siemens P/N is 2357J These parts do not have replaceable elements. There are 32 flashback sensors per turbine.
The Conax price and availability is better than that from Siemens direct and other sensor manufacturers are limited. One competitor, LPG may be out of business.
We do not have a product bulletin for these sensors.

36. Siemens Flashback Sensors

37. Siemens Exhaust Rake Sensors

38. Other Siemens sensors
Other sensors are also available for the Siemens turbines, such as air inlet and bearing sensors assemblies. These type sensors are not replaced on a regular basis but are replaced when there is a major outage or turbine over haul.

39. Sensors for Alstom GT24B Gas Turbine
TAT 2 rake
TAT 1 sensors

40. Alstom Gas Turbines GT24 Sites that have GT24 Turbines.
Iberdrola Energia Monterrey, S A De C V
Hermosillo
Central Termoeléctrica Presidente Juárez (Rosarito III & IV, BC)
Valle de Mexico IV (GT11N2)
We have limited information for older Alstom Turbines. We are supplying several sensors to them for new machines, however they assign new part numbers for every supplier.

41. Alstom Gas Turbines GT24
The best approach for securing this business is to:
First get the OEM part number so we can check and see if we have the drawing files on record.
See if we can get a failed unit to reverse engineer.
The next two slides will show examples of sensors we have done.

45. Sensors for Mitsubishi M501F Gas Turbines
Exhaust rakes
Blade Path sensors
Disc Cavity
Flashback sensors

46. Mitsubishi M501F Gas Turbines
The sites that have Mitsubishi M501F Turbines are:
CFE Chihuahua -El Encino
Tuxpan III & IV
Tuxpan –V
The Mitsubishi M501F turbine was derived from the Westinghouse W501F turbine.
The names of the sensor locations are the same but the parts are unique to the Mitsubishi machine

47. Mitsubishi M501F Gas Turbines
Mitsubishi assigns unique part numbers for every power plant.
The plant operators have this document and we need it for the specific product.
Like Alstom machines, we can always reverse engineer a used part.
The leadtime for replacement sensors is very long and the prices are very high. This puts us at a real advantage and RM in a position for more $$$.

48. Mitsubishi M501F Gas Turbines
It is well worth the effort to get the plant listing for the thermocouples. On the next page is an example of a typical Blade Path sensor used on these machines.
There are 16 Blade path sensors per machine. Your cost from us is around $ each. With your mark up you will still be cheaper and faster than the OEM can supply.

50. Sensors for GE Frame 5 (500KAPPP) Gas Turbines
Sites that have GE 7FA’s
Iberdrola Energía La Laguna (Laguna II)
Depending on the age of the Turbine this may have been manufactured by Nuovo Pignone in Italy.
It is best to get the original equipment part number and we can supply the parts. Some parts may have the old GE numbers and some parts may have an RTO-xxxxx number from Nuovo Pignone.

51. Conax designed Sensors for Gas Turbine upgrades
We have designed many of our own sensor products that either improve the life of the sensor or makes the maintenance at the plant easier. These products are not supplied by the OEM, they can only be supplied by Conax. All of these product bulletins can be found on our FTTP site at:

52. Conax designed Sensors for Gas Turbine upgrades
Bulletin 6064: Highly Reliable Retrofit Exhaust Gas Sensors for older frame 5, 6, 7 & 9
This allows the plant to upgrade to a newer sensor and cable system without having to change the radiation shields that can be costly to change. These parts apply to the GE 7EA and Frame 5 machines.
Bulletin 6054E: Enhanced Exhaust Gas Thermocouples
This is a spring load version to the exhaust gas sensors used on the GE 7FA. This makes the sensors more reliable and reduces the problem from the OEM with the tips breaking off.

53. Conax designed Sensors for Gas Turbine upgrades
Bulletin 6067: Retrofit Blade Path Thermocouple Kit for Siemens Westinghouse Turbines
This allows the plant to upgrade to a more reliable sensor than the OEM provides as well as have quick disconnect Plugs and Jacks so the entire cabling system can be removed during engine maintenance. This design applies to the W501 series of turbines.
