Description : FYKAYS offer two distinct types of
IN-SITU PROBES
Reaction Bonded: (RB) unsheathed probes
Fusion bonded: (FB) sheathed probes
Reaction bonded probes, which can be used without external sheathing and the associated assembly and maintenance problems make use of a patented process in which a ZrO2 thimble or pellet is bounded onto an Al2O3 tube by reaction through a platinum washer.
Fusion bonded sensors on the other hand use sintered ZrO2 pellet cemented and fused to the Alumina tube
Wider applications :
Length of Probes
Standard lengths available are 150, 300, 600, 900, 100, 1200 and 1500 mm. Longer lengths up to 2500 mm available on special request.
Thermocouple Specifications
For RB sensors the thermocouples are normally type 'R' or 'S' (Pt.Pt.Rh 13 % or Pt.Pt.Rh 10 %)
For FB sensors the choice is extended to 'K' type (chromel-alumel), for lower temperature applications. For extra temperatures probes are supplied with 'B' type
(PtRh 6% - Pt 30 %) thermocouples (RB sensors only) thermocouples (RB sensors only)
