A-500 thermowell is machined from a single piece of brass
or stainless steel to provide a rugged and leakproof well
for MAMAC Systems' temperature sensors. Each A-500 thermowell
is precisely machined to 0.255" bore to provide a
tight fit for our standard ¼" O.D. probe. This
feature also significantly enhances the thermal transfer
from the media to the temperature sensor.
external and internal threads are machined to meet published
and each well is individually inspected to insure thread
integrity. Hexagon wrench flats are provided to assist
in installing the well in the pipe. Other thermowells that
incorporate dissimilar metals like brass
and copper which are welded/soldered together are susceptible
to leaks caused by thermal shock. In HVAC applications,
the temperature of the media may change rapidly, and due
to different coefficient of thermal expansion, a welded/soldered
thermowell may leak. The A-500 thermowell has a single
piece construction and, as a result, is immune to leaks
which may be caused by thermal shock or weak welds.
MAMAC A-500 thermowell is available in 4", 6",
12" lengths to handle pipe diameters
from 4" to
more than four length options, brass and stainless steel
choices, three external thread options, solid leakproof one piece construction,
and precision machining, the A-500 thermowell can reliably
accommodate all HVAC immersion temperature sensing applications.
order to improve thermal transfer and to eliminate condensation
forming within the thermowell, MAMAC Systems offers a high
grade thermal compound (A-505) for
the A-500 thermowell.
