Ordering Information
Aspirated Thermocouple
ASPTC
Aspirated Thermocouple with Radiation Shield.. Must specify
signal and power cable lengths (see below).
Cable Lengths
-L
After the -L, enter the signal cable length in feet. A 15-ft
length is typically used.
-LP
After the -LP, enter the power cable length in feet. A 15-ft
length is typically used.
Mounts
UT018 -5
Tower Mounting Bracket with 5-ft Crossarm
Mounting
The ASPTC can be mounted to a tripod or tower via the UT018-5
crossarm or a user-supplied crossarm that has a square cross sec-
tion of 3.8 cm by 3.8 cm (1.5 inch by 1.5 inch).
Power Considerations
The ASPTC is typically powered with a user-supplied deep cycle
battery that is recharged with an SP20R, SP50, or SP90 solar panel;
for high current drain systems two SP90 solar panels may be used
to provide 180 W of power. The datalogger’s rechargeable bat-
tery can only be used if it is connected to ac power. For help on
analyzing your system’s power requirements, refer to our Power
Supply brochure or application note.
