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)
