Sensors - Marlox Thermocouples-Junction Type
Thermocouple
Junctions
All
junctions are welded by the tungsten inert gas method to insure
performance and to prevent contamination of marlox thermocouples.
Exposed
Junction
Bare
thermocouple wires are welded to form a junction that extends
beyond the sheath for a distance equal to the sheath diameter.
Used where fast response is required and contamination is not
a factor.
Grounded
Junction
The
thermocouple junction is welded directly to the sheath. Provides
good thermocouple protection against pressure, moisture and mechanical
damage yet retains good response characteristics.
Ungrounded
Junction
The
junction is electrically and mechanically insulated from the sheath
for long life characteristics under maximum corrosion, thermal
shock, and vibration conditions.
Dual
Element Junction
Dual
element Marlox provides two circuits for simultaneous response
from a single thermal point. Exposed, grounded or dual ungrounded
are available. In Marlox 0.125" diameter and up the dual element
ungrounded thermocouple junctions are insulated from the sheath
and each other. Smaller diameter Marlox dual ungrounded junctions
are insulated from the sheath but not from each other.
Weld
Pad Junction
The
junction is used as a means of attaching Marlox to surfaces such
as boiler tubes and pipes to provide efficient surface temperature
measurement. Standard construction utilizes grounded or ungrounded
junction Marlox welded to an alloy pad (1" x 1" x 1/8") of the
same composition as the sheath. Tube skin perpendicular and parallel
pad arrangements are available.
