OPTIONS / MODIFICATIONS
HIGH TEMPERATURE TERMINATION
In applications where cold end termination will see temperatures in excess of 200ºC, standard epoxy seals may breakdown causing failure. In this case ARi can supply a ceramic cement seal which can withstand temperatures up to 450ºC.
To specify this option, add the prefix HI- in front of the part number selected.
Example: HI-T-107N-12DAE(9.5)N
DUPLEX ELEMENT CONSTRUCTION
Most thermocouple combinations with an outside sheath diameter of 1/8″ or larger are available in duplex element construction (2 separate measuring circuits in 1 sheath).
To specify this option, add the suffix .4 after the style number and “repeat the junction code a second time and add parentheses”.
Example: T-91.4N-12FR(9.9)B or T-91.4B-18DAE(9.3)(9.3)O
MATING JACK
If required with any of our male plug type thermocouples (T-91, T-191, and HI-T-91), we can supply the appropriate mating jack with the assembly.
To specify this modification, add (MOD) after the part number and specify “Supplied With Mating Jack” .
ARGON BACKFILL
In order to minimize the effects of any residual oxidation remaining inside non-compacted sheath designs, ARi can evacuate and backfill the sheath with inert Argon gas prior to sealing the cold end.
To specify this modification, add (MOD) after the part number and specify “With Argon Backfill” in the description.
SPECIAL LIMITS OF ERROR
Thermocouples with R, S & B calibrations made with mineral insulated construction can be supplied with special limits of error tolerances per ASTM E-230 or Class 1 per IEC-584 subject to availability of material from stock.
To specify this modification, add (MOD) after the part number and specify “Per Special Limits of Error” or “Per Class 1 Tolerance” in the description.
TEFLON INSULATED EXTENSION WIRES
For designs where extension wire attachment is required, we can supply moisture resistant Teflon insulated extension wire in place of our standard fiberglass. Other insulation types can be supplied subject to availability.
To specify this modification, add (MOD) after the part number and specify “With Teflon Insulated Leads” in the description.
