The Telaire Humitrac Humidity Transmitter is a relative humidity and temperature transmitter
designed to serve the building automation/HVAC market, as well as a wide variety of general
purpose relative humidity monitoring applications. All models of the HumiTrac incorporate a
NIST traceable, field-replaceable sensor tip, a rugged capacitive sensing element capable of
full-scale 0 to 100% relative humidity measurement, and a host of field configurable output options.
Enhanced Field Serviceability
The 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 HumiTrac's sensor
module and uploaded to the humidity/temperature transmitter instantly. This virtually eliminates the
need for time consuming and costly factory calibration, while reducing downtime during service
intervals to near zero.
Unsurpassed Sensor Performance
The HumiTrac relative humidity and temperature transmitter from Telaire 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 to 140°F (-40 to 60°C).
Maximum Flexibility
These RH/temperature transmitters from the HumiTrac Series are designed to
be highly configurable in the field or in your warehouse. By minimizing the necessary number
of configurations, distributor inventory costs are reduced and maximum flexibility is provided to
the installer. All versions of the HumiTrac feature field-selectable outputs (0 to 5V, 0 to 10V, 4
to 20mA), and passive temperature versions incorporate both a 3K and 10K S thermistor. Simple
adjustment of slide switches is all that is required. Signal-conditioned temperature versions are
available scaled from 32 to 122°F (0 to 50°C) or -40 to 140°F (-40 to 60°C).
Custom ranges are available upon request for high volume applications. The
HumiTrac is available in humidity accuracies of
±2%, ±3% or ±5% and is offered in wall mount, duct mount, and outdoor air
configurations.
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.
Simple, Fast Installation
HumiTrac transmitters feature large, removable, pluggable
terminal blocks, which eliminate 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 of the HumiTrac 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.
