The HX80A Series is a family
of humidity probes that offer
a variety of measurement
parameters with precision
accuracy: relative humidity and
temperature, with dew point or
pressure. The probe is easily
adaptable for most applications
via a 3?4 NPT fitting that can be
adjusted to any desired position,
including high temperature and
high pressure conditions. This
remote type transmitter comes
standard with a 1.8 m (6') cable
and is ideally suited for many
different applications such
as environmental chambers,
compressed air, and industrial
applications.
Models offer a stainless steel
probe with a removable sinter
stainless steel filter and RS232
(which allows for reading of data,
scaling output, and for HX86A
type units, changing the digital
display and setting the alarms).
All models have 3 outputs, with
output 1 scaled for 0 to 100% RH,
output 2 scaled for -20 to 120°C
(-4 to 248°F), and output
3 determined by the model
number. Output 3 for HX85A
and HX86A is -60 to 40°C
(-76 to 104°F) dew point, for
HX85BA and HX86BA is 750
to 1100 mb, and for HX85PA
and HX86PA is 0 to 200 psia.
RH measurement range is 5 to
95% with an accuracy of ±1%.
temperature accuracy is
±0.5°C (33°F).
HX85A (probe only) models
(HX85A, HX85BA, HX85PA) offer
0 to 10V signals on the outputs
via a 1.8 m (6') cable. The HX86A
models (HX86A, HX86BA,
HX86PA) include a display box
attached to the end of the cable
from the probe, and offers a 2 line
digital display, 2 alarms, three
4 to 20 mA output signals, and an
RS232 serial output.
