Hx-67x3 Series Outdoor Relative Humidity Transmitter

Johnson Controls Hx-67x3 Series offers a full line of
outdoor Relative Humidity (RH) transmitters for
measuring and transmitting RH levels from 0 to 100%.
The RH transmitters provide excellent reliability,
long-term stability, and fast, accurate response to
changes in humidity. Certain models come equipped
with a temperature transmitter.
The humidity sensor is impervious to dust and most
chemicals, and it is unaffected by condensation. The
unique weather shield protects the sensors from solar
radiation and precipitation without affecting
performance. The multiple discs have a unique profile
that permits easy passage of air. The disc material is
especially formulated for high reflectivity, low thermal
conductivity, and maximum weather resistance. This
rugged enclosure will ensure a long life, even under
extreme weather conditions.
The sensor and shield function as one unit for optimal
performance. The RH transmitter can be easily
mounted on a roof, pole, or side of a building utilizing
its preassembled mounting bracket. It requires no
routine maintenance or recalibration.

Product Overview

The outdoor RH transmitters incorporate an
advanced-capacitive, thin-film humidity sensor
designed for demanding humidity measurement
applications where high accuracy is important. The
thin polymer film either absorbs or releases water
vapor as the relative humidity of the ambient air rises
or drops. The dielectric properties of the polymer film
depend on the amount of water contained in it: as
the relative humidity changes, the dielectric
properties of the film change, so the capacitance of
the sensor changes. The electronics of the
instrument measure the capacitance of the sensor
and convert it into a humidity reading. The
repeatability, stability, and performance of the
sensors have been proven in many industrial control
processes under extremely harsh conditions.
The shield provides a rugged, weatherproof
enclosure for the transmitter while maintaining

accurate performance. The multiple-plate design
allows for maximum airflow for precise
measurements. The disc material is especially
formulated for high reflectivity, low hermal

conductivity, and maximum weather resistance. This
enclosure will ensure a long life, even under extreme
weather conditions.
Why Measure Relative Humidity

Humidity is an important aspect of any climate
control system. The significance of indoor air quality
to our health has become evident. Humans are best
suited to and feel most comfortable within a fairly
narrow range of humidity and temperature, whereas
extremes, high or low, cause discomfort.
Accurate outdoor humidity measurement allows the
necessary steps to be taken indoors to ensure a
quality air environment.

Energy Savings

The right humidity level optimizes energy consumption.
In energy management projects with hundreds of
setpoints, it is normal to have only one outdoor humidity
sensor. If that sensor is not accurate, energy costs may
rise, and the building occupants’ comfort may suffer. The
maintenance-free, accurate, long-lasting performance of
these transmitters will keep energy costs low and
building comfort levels high. These transmitters are

compatible with most energy management systems.
In an economizer application, the enthalpy switchover
cycle uses the outdoor RH reading. It chooses whether
the mixed air system should be using outdoor air for free
cooling, return air by measuring the total heat content, or
enthalpy of each air stream. Thus this application
maximizes energy efficiency within the system.
