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. |
| 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. |
