Relative Humidity Control System

The HX93A and HX93DA Series interface
directly with OMEGA’s iSeries meters and
controllers to create a complete relative
humidity control system.
iSeries meters and controllers
feature totally programmable color
displays and embedded internet
connectivity. Visit omega.com

HX93AC wall

mount.

The HX93DA and HX93A Series
transmitters provide remote and
on-site monitoring of relative
humidity and temperature. Both
series output a linearized current
or voltage signal proportional
to the measured humidity or
temperature. RH outputs are
temperature compensated. Current
output models enable placing of
the transmitter at a remote location
virtually any distance away from
the measuring device. The HX93DA
models feature built-in dual displays
that indicate both humidity and
temperature simultaneously. All
use a thin-film polymer capacitor
to sense relative humidity and a
Platinum 100 Ω RTD to sense
temperature. A stainless steel
mesh type filter, easily removable
for cleaning, protects the sensors.
Mounting screws are easily
accessible inside the rugged,
polycarbonate enclosure which
houses and protects the electronics
to NEMA 13 specifications.
