The HX400 Series transmitters
provide remote and on-site
monitoring of relative humidity and
temperature. Each parameter is
transmitted as a 4 to 20 mA signal
to remote receivers.
The HX400 is a programmable
2-wire field mounted humidity/
temperature transmitter for use
in environmental air monitoring
and system. Its state-of the art
design combines digital capacitor
humidity/temperature chip and
microprocessor-based linearization
with temperature drift compensation
technology offering proportional,
linear, and highly accurate dual
4 to 20 mA output current in a
variety of applications.
The HX400 integrates functions
of transmitter, indicator and
alarm outputs in one unit. All
directly measured and computed
parameters are configured via front
3 pushbutton without personal
computer involved. Dual
3-digit 7-segments LED
display module indicates
the values of the measured
parameters in measuring mode
or prompting the programming
instructions during setup mode
and calibration mode. The current
output models enable placing of
the transmitter at a remote location
virtually any distance away from
the measuring device. The HX400
models feature built-in dual displays
that indicate both humidity and
temperature simultaneously.
