Enhanced Field Serviceability
HumiTrac features a National Institute of Standards
and Technology (NIST) traceable, field-replaceable
sensor tip module that allows the end user to replace
the sensor on-site while maintaining ±2% RH accuracy
and NIST traceability. The user simply powers off the
unit, installs the new sensor module and powers back
the unit. All necessary calibration constants are stored
in the memory of the sensor module and uploaded to
the transmitter instantly. This virtually eliminates the
need for time consuming and costly factory calibration,
while reducing downtime during service intervals to
near zero.
Rugged, Attractive Enclosures
All HumiTrac configurations feature rugged flame
retardant, UL-94V ABS plastic. Duct and outdoor air
versions provide excellent weather resistance (IP42
rated). Special care has been taken in the design
of the wall mount enclosure to provide enhanced
airflow, increasing sensor response time and virtually
eliminating the potential of “self-heating” by transmitter
electronics that can lead to decreased accuracy
measurements.
Unsurpassed Sensor Performance
HumiTrac utilizes a rugged capacitive sensor that
provides full-scale 0-100% RH measurement with
unsurpassed response times, linearity and stability.
Recovery to condensation and chemicals is excellent
and an integrated filter, plus conformal-coated module
electronics ensure long life. All sensors undergo a ten
hour digital calibration, certified against a primary NIST
reference standard. Signal conditioned temperature
versions maintain specified RH accuracy across the full
operating range of -40°F to 140°F (-40°C to 60°C).
Simple, Fast Installation
All HumiTrac models feature large removable,
pluggable terminal blocks, eliminating the need to
wire in a confined space and allow the unit to be pre-
wired separate from the electronics—an especially
attractive feature in unfinished construction, where
exposed sensors and electronics could be damaged by
moisture, drywall dust and paint. All models incorporate
a retaining wire that attaches the cover to the base,
allowing the installer to wire the unit without using an
extra hand to hold the cover.
Maximum Flexibility
HumiTrac is designed to be highly configurable in the
field or in your warehouse. By minimizing the necessary
number of configurations, Telaire reduces distributor
inventory costs and provides maximum flexibility to the
installer. All versions feature field-selectable outputs
(0 to 5V, 0 to 10V, 4 to 20mA) and passive temperature
versions incorporate both a 3K and 10K W thermistor.
Simple adjustment of slide switches is all that is
required. Signal-conditioned temperature versions
are available scaled from 32°F to 122°F (0°C to 50°C)
or -40°F to 140°F (-40°C to 60°C). Custom ranges are
available upon request for high volume applications.
HumiTrac is available in humidity accuracies of ±2%,
±3% or ±5%, and offered in wall mount, duct mount
and outdoor air configurations.
Lowest Cost of Ownership
With a two-year warranty*, simplified inventory
management, reduced installation times and field-
serviceability, HumiTrac sets the standard in reduced
cost of ownership and performance-to-price ratio.
*Transmitter only, one year warranty on replaceable sensor.
