Thermocouples
Insulated
Metal sheathed cables with thermocouple conductors
which are insulated from each other and the sheath by
highly compacted magnesium oxide.
BJ
Bonded
EJ
Conductors are safe from environmental
Exposed
contamination, ductile and highly responsive.
ExJ
Extended
The cables are water, oil and gas resistant, extremely
robust and are eminently suitable for applications
where high or low temperature, corrosion, vibration,
pressure and other extreme conditions exist.

Advantages
●
Rapid response - due to small thermal capacity of
conductor bead and high thermal conductivity
of insulant
Cold End Terminations
●ꢀ
Ductile - can be easily bent or formed
Completely immune from thermal shock
Small overall diameters
Very high insulation resistance
Unaffected by pressure - can be glanded
through bulkheads or pressure vessel walls.
Extensive range of diameter, conductor and
