United Sensor features a unique line of
Aspirated Temperature Probes for high
velocity and/ or high temperature use. The probes are designed
for use with an
aspirating pump and metering orifice to
draw measured
fluid past the hot junction
at a desired velocity (see figure below). |
in all velocities and temperatures below 500°F. External shield has an open tip.
Standard
diameter: 1/4"
|
TJ:
Most versatile and accurate probes for all velocities and temperatures up to
2000°F. Requires bleed line for aspirating gas and source of suction if
rig pressure is less than 2" Hg. above atmospheric. Thermocouple element removable
for calibration. Completely pressure tight assembly. Suitable
for measuring reference temperatures. Radiation multi-shielded sensing head,
aspirated, with removable thermocouple element, when requested, for use in all velocities.

TL:
For Zones 1, 2, and 3 primarily; also
accurate in Zones 4, 5, and 6 because
of
low radiation loss from silver-coated
thermocouple; maximum
1600°F. Only
effective in gas that does not tarnish
silver.
Element removable, when requested, for calibration
and polishing. External shield
has an open
tip.
TLI:
For Zones 1, 2, and 3; can also be used in
Zones 4, 5, and 6; maximum
2000°F.
Requires aspiration. Inconel covered
thermocouple is
removable. External shield
has an open tip.
TK:
For Zones 1, 2, and 3 primarily; can also be
used in 4, 5, and 6 where
space is limited.
Requires aspiration. Also useful for
measuring
fuel-vapor mixture temperature.
By pointing entrance downstream and
upward,
the flow reversal and aspirator
drain off liquid fuel thrown
onto shields and thermocouple reads true gas
temperature. Nichrome
shielded
thermocouple element for use |
